Christmas cactus gets a lot of attention in November and December, and then basically nothing for the rest of the year. That benign neglect works out fine sometimes, but April and May are those months where a little attention goes a long way. The plant just finished – or is finishing – its spring flush, new segments are starting to push out, and the conditions it needs right now are quite different from what it needed two months ago.

Getting a handle on Christmas cactus care through the seasonal transitions is what keeps these plants looking good year after year – Schlumbergera can live for decades with the right handling, and spring can either build toward that or quietly work against it.

None of these tasks takes long, and they are also applicable to the other types of holiday cactus, particularly the Thanksgiving cactus. Most are just small course corrections – adjusting what the plant gets as the season changes underneath it. Done consistently, they make a real difference.

1. Let It Rest After Blooming

If the plant just finished its second flowering in spring, it's very tired. Christmas cactus puts a lot of energy into producing blooms, and once they're done, the plant needs a quieter stretch to recover before it starts pushing new growth in earnest. The instinct to start fussing with it – moving it, repotting, adjusting its feeding – is usually the wrong call right after bloom.

For a few weeks in April, the best thing is to ease off. Keep watering consistently, but don't increase it; hold off on fertilizer until new segments are actively growing, and don't relocate the plant if it's in a decent spot. Skip the rest, and the plant tends to go into summer looking scraggly rather than building dense growth that leads to heavy flowering later on.

2. Deadhead Any Spent Flowers

Spent blooms don't fall off on their own – they sit there drying out on the stem tips and can slow down the transition to new growth. Removing them is quick work. Just twist each dried flower gently at the base of the bloom where it meets the segment, and it usually comes away clean. No tools needed for this part.

While deadheading, check the stem tips for any segments that look shriveled, mushy, or discolored. Those can be pruned at the joint, too – clean cuts help, so use sharp pruning scissors, like these Fiskars ones on Amazon. Soft segments that feel mushy all the way through, rather than just dry at the tip, often point to an overwatered Christmas cactus or rot working its way up from the roots.

3. Pull Back on Watering

Right after blooming, Christmas cactus actually wants less water than it did during the active flowering period. The plant's metabolism slows a bit, it's not pushing flowers anymore, and the risk of overwatering goes up if the schedule doesn't adjust. Let the top inch or two (2.5–5 cm) of soil dry out fully before watering Christmas cactus, and when you do water, soak it thoroughly and let it drain – don't let it sit in a tray of water.

This is also a good time to check that the potting mix is still draining the way it should. Christmas cactus planted in regular potting soil instead of something chunkier tends to hold moisture too long, especially in spring when the plant isn't drinking as aggressively. A well-draining cactus mix, like this Top Tier Genetics Premium Christmas Cactus Soil on Amazon, handles the wet-dry cycle much better and reduces the chance of root issues developing quietly over the summer.

4. Start Fertilizing Once New Growth Appears

Don't rush the fertilizer. Feeding a Christmas cactus that's still in post-bloom recovery doesn't do much good and can stress it. Wait until new segments are visibly pushing out from the stem tips – that's the signal the plant is ready to use what you give it.

Once that new growth starts, a balanced water-soluble fertilizer at half strength every two to four weeks works well through spring and into summer. Something with a roughly equal NPK ratio is fine – the high-potassium formulas pushed specifically for cactus are more useful later in the year when you're trying to encourage bud set. For now, balanced is better.

This TPS Nutrients Christmas Cactus Fertilizer dilutes easily and is gentle enough to use regularly without overdoing it.

5. Pinch Back for Fuller Growth

April to May is a good window to pinch back the stem tips, and it's worth doing while new growth is just getting started. Christmas cactus only blooms at the tips of its segments, so more branching means more potential bloom sites come fall and winter. Pinching – just removing one or two segments from the end of each stem – encourages the plant to branch rather than keep extending in one direction.

It feels counterintuitive to remove growth you just watched come in, but it pays off. Set the removed segments aside to callous over for a day, then you can propagate Christmas cactus by potting them in barely moist cactus mix – spring cuttings have the whole growing season to establish. It's worth doing if the plant's gotten leggy or lopsided.

6. Check the Pot and Roots

Christmas cactus doesn't need repotting often – it blooms better slightly root-bound – but spring is the right time to check if it's been a few years. Roots poking out of the drainage holes or a plant that dries out unusually fast are the signs. Go up one size only; too much extra soil holds moisture the roots can't use and invites rot.

If the roots look okay but the potting mix is old and compacted, a top-dressing is often enough – scrape off the top inch or so (2.5 cm) and replace it with fresh cactus mix rather than doing a full repot. Do any of this now, in spring, rather than waiting until buds are forming in the fall. Disturbing the roots close to bud set is one of the more reliable ways to end up with bud drop.

These Meshpot slotted orchid pots work surprisingly well for Christmas cactus, too – the extra airflow around the roots keeps things from staying wet too long.

Christmas Cactus Spring Essentials

Into Summer and Beyond

Christmas cactus wants to be left alone through summer – consistent watering, decent indirect light, and monthly feeding. The heavy lifting for next year's bloom cycle starts in fall, when cooler nights and longer darkness trigger bud set. Spring is really just about making sure the plant is healthy and well-structured before that process begins.

Keep an eye on the foliage through summer. Pale, yellowish segments usually mean too much direct sun. Dark green but soft and limp often points to overwatering. A plant that looks dense and holds its color well through the warmer months is almost always the one that puts on the best show come December – and getting there starts with the right habits now, in spring.

The holiday decorations may be back in the attic, but our beloved Christmas cacti soldier on. However, they may be starting to look a little past their best once we head towards the latter stages of winter. If your Christmas cactus looks a little weary, you might be thinking it’s done for another year, but the start of the year is actually a golden opportunity to kickstart a second flush of flowers.

While many treat them as seasonal flowering plants with limited ongoing visual interest, these resilient succulents have a secret: they are perfectly capable of a spectacular encore in spring. Knowing how to get a Christmas cactus to bloom again in spring isn’t down to a fluke – it’s simply about respecting the internal clock of the plant. Give your Christmas cactus the right care during this post-holiday slump, and you can transform that greenery into a stunning second act of vibrant color.

Native to Brazilian rainforests, Schlumbergera often has a second flowering season in early spring. Of course, our homes may not be quite as exotic as Brazil, but these epiphytic plants still crave a rhythm that mimics the shifts of their South American origins. Here's the secret to turning your tired plant into a vibrant spring showstopper.

The Secret Key to More Blooms

For anyone keen to find out how to get Christmas cactus to bloom again, the secret to a spring showing is simple. It’s all about embracing the “slump” and leaning into the idea of a January rest period. Put simply, the slump is a natural part of the plant’s life cycle. Not only does it have to be observed, it should be actively encouraged.

In the wild, these plants experience a period of cooler temperatures and shorter days following their primary reproductive cycle. When we keep things at a cozy 72°F (22°C) with the lights on until late, the cactus never receives the important biological signal that it’s time to rest and reset. That sign, in turn, is what prompts the plant to stop growing leaves and start growing buds. To get that second flush, you must initiate a period of rest for 4-6 weeks, starting in late January.

To set new flower buds, a Christmas cactus requires cool nights, hitting a sweet spot between 55-65°F (12.8-18.3°C). Use a digital thermometer like the ThermoPro TP50 from Amazon to keep temperatures in this range. If you must keep things snuggly for yourself, move your plant to a cool room or basement. The drop in temperature will slow the plant's metabolism, so it stores energy rather than pushing out weak growth. To trigger spring bloom, light requirements must be shifted, too. A Christmas cactus needs 13-14 hours of darkness a day during this rest period.

You should also scale back watering your Christmas cactus during this period. You want the soil to feel dry. If you aren’t sure how much to water in the rest period, try the wrinkle test. Gently squeeze one of the flat, leaf-like segments (phylloclades). If it feels firm, there is plenty of stored moisture. If it shows fine wrinkles and feels limp, add a little top-up. This mild drought, chill and dark all mimic a Brazilian dry season, which is the natural foundation for the next Christmas cactus flower burst.

3 Ways to Get Christmas Cactus to Rebloom

Once your Christmas cactus has enjoyed its quiet January hibernation, you can nudge it gently back to life. The following 3 steps are designed to work in harmony to encourage that dynamic second flush. Here’s how to make a Christmas cactus bloom again in a thoughtful way, and with minimum fuss.

1. The Light and Water Pivot

In late February or early March, move your cactus back into a spot with bright, indirect light. An east-facing window provides enough morning sun to fuel photosynthesis, without the harsh afternoon rays that can scorch segments. If you need a little extra light at this time, position your plant under a full-spectrum grow light, like the Glowrium Height Adjustable Grow Light from Amazon.

As the light increases, you must also slowly reintroduce moisture. Instead of a deep soak, start with light waterings using room-temperature water (either distilled or rainwater is preferable). Your Christmas cactus is sensitive to the shock of cold tap water, which can cause bud drop before the flowers even open. At this point, keep the soil moist but never soggy. Water when the top inch of soil feels dry to the touch.

2. Strategic Deadhead and Prune

To maximize your spring flush, make sure flowers have the best chance of developing well. Start by gently twisting off any shriveled December blooms. Deadheading prevents wasting energy on seed production. For a truly lush encore, perform a light pruning. Use Fiskars Micro-Tip Pruning Snips from Amazon (or sharp flower snips or scissors) to make clean cuts at the joints without damaging main stems.

As an alternative to pruning, try pinching back. Identify the phylloclades (those flat, leaf-like segments) and remove a couple of segments from the end of each branch. This stops the plant from becoming leggy and sparse, and encourages the stems to branch out. Since Christmas cacti only produce flowers at the tips of their stems, doubling the branches effectively doubles your potential for spring blossoms.

3. Gentle Nutrient Boost

Hopefully, you didn’t feed your Christmas cactus during the January rest. However, once you see tiny buds or new red-tinted leaf growth appearing (some time in late February), it’s a good idea to support growth with targeted fertilizing. Use a high-potassium liquid fertilizer or specialized cactus and succulent food, like Schultz Cactus Plus (2-7-7) from Amazon, to boost flower production (dilute to half-strength).

Potassium is the key mineral for flower development and root health (whereas high-nitrogen fertilizers prompt more green foliage). Feed the plant every 2 weeks through the spring blooming period. There’s no need to go heavy on feeds, though and a little goes a long way. Once the spring flowering ends, you can reduce feeding to once a month through summer.

But Don't Do This!

That’s all you need to create the ideal conditions for that lovely second flush. However, a few things are best avoided if you want to know how to get a Christmas cactus to flower again with zero stress:

• Don’t repot during bud set. A bigger pot does not mean more flowers. Christmas cacti actually bloom best when slightly root-bound. If you repot these plants now, they will focus on its root system, rather than producing flower buds. If the soil does look depleted, top-dress with a dedicated succulent or cactus mix like Back to the Roots Organic Succulents & Cacti Mix from Amazon.
• Don’t move once buds appear. A Christmas cactus can be fussy about its environment. Relocating it near heat vents or drafty windows can cause bud drop. Even rotating it 180 degrees can cause the plant to drop its buds in stress. Find its bloom spot before it blooms, then leave it there until the show is over.
• Don't rely on kitchen hacks. You may hear that sugar water or coffee grounds can trigger further flushes. These hacks shock the plant into blooming. However, sugar can foster harmful bacterial growth in the soil, and grounds can make the soil too acidic and lead to mold. So stick to balanced, water-soluble fertilizers.

A blooming Christmas cactus is a joy to behold around the holidays. These beauties are tropical cacti native to South American jungles. Unlike their desert-dwelling cousins, Christmas cacti enjoy higher levels of humidity and can look quite sad if they don’t receive enough. Your Christmas cactus might even drop its blooms if the soil becomes too dry.

Christmas cactus plants draw moisture from their soil as well as the air around them. This is why many people suggest misting a Christmas cactus to keep the humidity levels up. But houseplant experts agree, don’t even bother with misting.

Misting your Christmas cactus isn’t effective and is a waste of your precious time. Let’s explore a better way to properly take care of your festive friend.

Skip the Misting

Christmas cacti are epiphytes who rely on moisture from their soil and also in the air around them. In the winter months, while our furnaces are pumping out hot, dry air, your festive plant is going to crave more moisture. However, misting your plants only raises the relative humidity of the air surrounding them a negligible amount. And misting is a very inconsistent method of increasing humidity. What happens if you forget for a day or two or leave town over the holidays? Your Christmas cactus won’t do well.

In addition to the inconsistency and inconvenience of misting your plant, if you mist too much you might end up with other problems like fungus and root rot. Stagnant humidity on the leaves and soil can lead to fungus growth that can kill your Christmas cactus and wreak havoc on your whole houseplant collection.

What To Do Instead

Skip the misting all together and try a simple and efficient alternative: the humble pebble tray, which is available on Amazon. A pebble tray is a shallow dish filled with pebbles, rocks or large aquarium gravel and water. It sits under your Christmas cactus and steadily raises the humidity around it without you lifting a finger. Just fill your pebble tray with water and let it go to work. Ensure that the water level is below the tops of the top layer of pebbles so the plant doesn’t soak up the water through the bottom of its pot and become sodden. It’s as simple as that!

Take care of the regular watering needs of your Christmas cactus by watering it when the top inch of soil is dry. You can stick a finger into the soil to check or you can use a soil moisture meter like this 4-in-1 soil moisture meter from Amazon.

Create Your Own Pebble Tray

You can create your own pebble tray by filling a plant saucer or shallow tray with decorative rocks. Don’t even bother to mist your Christmas cactus. Let a simple pebble tray do all the work for you this holiday season.

That sad, shriveled, brown Christmas cactus on the windowsill isn’t necessarily headed for the compost bin. These plants are tough little survivors – many that look completely dead bounce back strong and bloom heavily the following year. The secret is catching the problem early and applying the right fix without delay.

Learning how to revive a Christmas cactus – even one that appears totally gone – boils down to two dead-simple tests and a handful of targeted changes. Most supposedly dead plants are actually suffering from one of three common Christmas cactus problems: root rot, dehydration, or environmental stress. Fix the cause, and the plant almost always returns.

Once stabilized, Christmas cacti are practically bulletproof. Christmas cactus care boils down to the exact same habits that just saved its life – bright indirect light, restrained watering, and cool nights. Nail those three things, and it will cascade over the pot with ridiculous numbers of hot-pink blooms every year like clockwork.

Is It Really Dead?

Before investing time and energy into reviving your Christmas cactus, first check to make sure it's recoverable by performing these two tests:

The Flex Test

Take a stem segment near the soil line and gently bend it between your thumb and finger. If the segment flexes instead of snapping cleanly, living tissue remains inside. Even segments that feel soft and limp may contain enough life to recover. Segments that crack like dry kindling are finished, but the base often stays pliable longer than the tips. Check multiple places – the lowest sections frequently stay viable when everything higher up looks hopeless. Recovery from here is absolutely possible and often happens faster than most people expect.

The Root Test

Tip the pot sideways and slide the root ball out – it usually comes free easily when trouble is serious. Healthy roots look white or creamy-tan and feel firm, almost elastic, when pinched. Black, mushy roots that smell like a swamp confirm rot has taken hold. Yet even severe rot won't necessarily kill the entire plant; as long as a few white roots cling to at least one plump segment, new growth can emerge. Dusty, bone-dry soil that weighs almost nothing points to the opposite problem – desperate thirst.

Fixing the Cause

If you suspect your plant is still alive, then move on to diagnosing and fixing the root cause. While most problems are cultural, sometimes Christmas cactus diseases are the culprit, so if adjusting care doesn't fix the problem, it's worth considering a disease.

1. Watering Issues

Improper watering is the most likely cause of a declining Christmas cactus. Are leaf segments wrinkled or shriveled? Then it isn't getting enough water. Or, are segments limp and mushy? If so, overwatering has likely led to root rot.

Overwatering

Christmas cactus root rot turns segments dull gray-green, limp, and squishy at the base. The pot stays heavy for weeks and often smells faintly of pond water. This is the fastest way Christmas cacti meet their end indoors.

Act immediately. Unpot the plant, rinse the roots gently under lukewarm tap water, and cut away every trace of black or slimy tissue with sharp, sterilized pruners. Allow the cut roots to air-dry on the counter for 12-24 hours until the cut surfaces are slightly callused.

Repot your Christmas cactus into fresh, gritty potting mix with perlite – this fast-draining Christmas cactus potting soil from Amazon works well. Keep the soil slightly dry at first, then water only when the top inch feels dry to the touch. Bright pink or green tips at the segment ends in four to six weeks indicate the rescue worked.

Underwatering

Chronic underwatering makes segments shrink into thin, puckered, raisin-like tubes. The pot becomes extremely light – lift it, and it practically floats. Reviving a wilted Christmas cactus often just means proper rehydration.

Bottom-water right away: set the entire pot in a sink or bucket of room-temperature water for 30–45 minutes so moisture wicks upward evenly. Drain thoroughly – never let the pot sit in water afterward. The segments begin plumping within a few days and look glossy again within a couple of weeks once consistent moisture returns. Using a simple moisture meter removes all guesswork forever – this 4-in-1 probe from Amazon pays for itself the first season.

2. Light Levels

Christmas cactus light requirements are a careful balance. Too much direct sun scorches segments brown and flat; too little light forces long, weak, pale growth that never blooms. Recovery demands the sweet spot in between.

Place the plant in bright indirect light – an east-facing window is perfect, or two to three feet back from a south or west window. Sheer curtains help diffuse harsh afternoon rays. During short winter days, adding a small LED grow light like this one from Amazon for 8–12 hours daily can encourage stronger, fuller new growth, often appearing within two to three weeks of correct lighting.

3. Correct Temperature

Temperature swings are brutal on Christmas cacti. Anything below about 40°F (4°C) can cause segment drop; sudden cold drafts can trigger it even at higher temperatures. Anything above the mid-80s°F (around 29°C) may slow growth if combined with intense sun or low humidity. Recovery happens fastest in steady conditions.

Keep the plant between 60–75°F (15–24°C) during the day while it heals. Avoid cold drafts, heat vents, or placement near exterior doors. Once new growth is obvious and segments firm up again, cooler nights of around 50–55°F (10–13°C) trigger flower buds for the famous holiday display. Plants given cool nights in early fall often bloom heavily in December and January.

Do Christmas cactus like coffee grounds? Christmas cactuses like acidic soil, coffee grounds are acidic... and you're just going to throw them out anyway! It seems like the perfect solution. And there is some truth to it, but not every leftover grounds habit fits the bill. A little knowledge goes far in avoiding the common pit falls that turn vibrant reds to limp greens.

So, does a Christmas cactus like coffee grounds as a steady diet, in reality? In moderation, they can nudge the pH just right, but if you overdo it you risk the opposite of what you're after. These epiphytic succulents originate from shady Brazilian forests, and they crave that slight acidic edge without the burn. Get the balance, and your pots stay compact and flower-packed; miss it, and roots suffer in silence.

The Benefit: Acidity Boost

When you give your Christmas cactus coffee grounds, you gently raise the acidity in a way that mimics the natural habitat that it’s used to, where leaf litter breaks down into humus-rich mix. Fresh grounds clock in at a pH of 6.5, close to the 5.5-6.5 sweet spot these plants prefer, helping unlock nutrients like iron that keep leaves deep green and buds plump.

It's not instant, but that slow-release kick can coax one more flush of blooms if your soil has gone neutral from tap water. The organic matter in the grounds is also useful to the soil structure. It works by attracting beneficial microbes and earthworms (if your cactus lives outside), aerating the mix and improving water retention in a way that supports the plant's preference for consistent but not excessive moisture.

During the active growth phase, sprinkle your used grounds very sparingly around the base every few weeks. We are talking about a small amount here – a tablespoon (15ml) per 6-inch (15cm) pot will do. Before you use them, however, rinse the grounds first to cut any bitterness. This is important because dry grounds absorb too much moisture and can compact like mud. When you keep up this practice over multiple seasons, you might find it leads to denser foliage and more vigorous reblooming from your Christmas cactus, turning that one-hit wonder into a reliably blooming holiday tradition.

Is It Safe?

Overzealous coffee grounds for Christmas cactus can tip the scales fast, compacting soil into a soggy brick that chokes roots. Those grounds will hold water quite well, and in that shallow pot, that means rot sets in without notice – stems start to soften at the base, blooms drop too early, and the whole thing slumps. It’s the complete opposite of that acidity perk. Too much actually lowers the pH below 5.0, and that locks out the phosphorus needed for those gorgeous flowers.

Gardeners often overlook these subtleties, thinking the decline is just overwatering rather than the actual amendment itself. This is why monitoring for early signs of Christmas cactus problems, like leaf-tip browning or unexplained segment loss, is so important before the damage becomes irreversible.

Watch for any yellowing tips or leggy growth as red flags – that's the plant's way of saying "enough is enough." In more humid homes, mold loves the damp grounds also, turning your windowsill into a gross science project. Pull back if you see it, and flush the pot with room-temp water to reset.

Beyond any physical compaction, the nitrogen bias in uncomposted grounds can skew nutrient ratios to unfavorable conditions. This promotes lush vegetative growth at the expense of flower production. The result is a cactus that looks leggy and sparse-flowered by the next holiday season.

The Best Way to Use Grounds Safely

Start small with coffee grounds for Christmas cactus to test the waters – mix 1-2 tablespoons monthly, then water through to dilute. Composted grounds work even better; they've mellowed to a neutral edge and add microbes without the grit. Layer under the mulch for pots heading outdoors in spring, where rain leaches the acid slow. A balanced approach pairs the grounds with some perlite for drainage – fill the bottom third of the pot to keep things airy. Track pH with strips every six weeks, or a 4-in-1 meter like this from Amazon. If it drifts low, add a pinch of lime.

For ongoing use, limit feedings to once a month during its peak growth. Always make sure to dilute this by mixing the grounds into a larger volume of neutral compost or leaf mold. This helps to buffer any sudden pH fluctuations. Positioning the pot in bright, indirect light helps, too. The acidic boost makes nutrients move around better, and this translates directly to more efficient photosynthesis. Stronger cellular walls result, and the plant can better resist the stresses of those crazy holiday humidity swings.

Other Ways to Get a Bloom Boost

Skip the grounds gamble and reach for something else to fertilize your Christmas cactus. A tiny splash of diluted coffee water or acidifying fertilizers sprayed on the leaves will give that acidic lift without soil mess. It can keep phosphorus flowing for fuller flowers. Azalea fertilizer sticks closer to the mark too, with its low-nitrogen formula that pushes buds over leaves. Organic kelp meal provides another reliable path – sprinkling a half-teaspoon around the base every six weeks supplies trace minerals and growth hormones that enhance resilience against indoor dry air, fostering a more compact habit and prolonged color display.

For a hands-off win, worm castings layer in neutral richness – sprinkle a quarter-inch around the base and let nature handle the rest. A perfectly blended liquid feed for Christmas cacti like this from Amazon dials in the right pH every watering, no measuring required. These swaps build long-term health, turning your cactus into a reliable holiday headliner.

Christmas Cactus Care Essentials

If you’ve ever proudly displayed a “Christmas cactus” in December only to notice it blooms earlier (or later!) you’re not alone. Holiday cacti are some of the most misidentified houseplants on the market, and there’s a good chance the one sitting on your windowsill isn’t a Christmas cactus at all, but (drum roll, please!) a Thanksgiving cactus.

Don’t worry,: the difference is subtle, the care is nearly identical, and once you know what to look for, you’ll be able to identify yours in seconds. Plus, you’ll be able to show off a bit when you flex your newfound knowledge down at your local garden center.

Up for a little horticultural learning, then? Of course you are! Here’s how to tell which one you really have.

1. Look at the Leaves

I know, I know; holiday cacti don’t have “leaves” – or, at least, not in the traditional sense. Instead, they have flattened stem segments called cladodes, and these segments hold the biggest visual clue.

Now, a true Christmas cactus (Schlumbergera x buckleyi) should have leaves with flat, smooth, gently scalloped edges; a little like they’ve been made with a cookie cutter. No sharp points, and absolutely no claws.

A bit like this...

On the flipside, a Thanksgiving cactus (Schlumbergera truncata) should have broad, pointed “teeth” or claw-like edges. This is why the Thanksgiving cactus is sometimes nicknamed the “crab cactus”; those cladodes should be pointy and angular, like little crab legs.

Check it out...

2. Note When It Blooms

Bloom timing is the second-biggest giveaway when sussing out if you have a Christmas or Thanksgiving cactus. Of course, this is where most people get confused, because stores often sell Thanksgiving cacti as Christmas cacti, but the clue’s in the name!

Your Thanksgiving cactus should bloom between late October to late November, to coincide with the holiday its named after. True Christmas cacti, like this one from Walmart, bloom between late November to late January (aka closer to Christmas).

They may also bloom a second time in spring if exposed to shorter daylight conditions.

It's Not Your Fault

Don't be upset if you made a mistake; most holiday cacti sold in the U.S. today are Thanksgiving cacti, not Christmas cacti, because they grow faster, ship better, and bloom earlier, which makes them perfect for holiday retail displays.

True Christmas cacti (y’know, the one with rounded segments?) are far less common and usually come from older family collections or specialist growers.

Your Christmas cactus essentials list:

So if you bought yours from a big-box store, grocery store, or garden center? There’s a very good chance it’s the Thanksgiving variety.

Don’t worry, though; both plants enjoy bright, indirect light, both prefer slightly cooler temperatures to set buds, both need short-day (long-night) conditions to bloom, and both like to dry out slightly between waterings. The only real difference is bloom timing, which is pretty helpful to know if you’re trying to plan holiday color.

Still, both are beautiful, resilient, long-lived and easy to encourage into yearly blooms… even if you do find one celebrating the holidays a little early.

Thriving for decades, the long-lived Christmas cactus remains a favorite of both novice growers and seasoned houseplant lovers. The plants' beauty, profuse blooms, and even the claim that they can help purify indoor air all make them ideal for holiday décor and for bringing color to winter spaces. They don’t need endless fussing over either, but if you want them to put on their best show, you’ll need to think about Christmas cactus light requirements right from the start.

A lot of people assume these plants behave like desert cacti, but that’s not the case. They actually come from shady forest environments, so the way they handle light is completely different – more like a woodland plant than a spiny succulent. And while light is especially important, good Christmas cactus care overall – from soil to watering routines – will give you the healthiest plants and the best holiday blooms.

Of course, other factors such as fertilizing and temperature also play their part. But if you’ve ever wondered, do Christmas cacti like sun? or how much light does a Christmas cactus need? then this guide will walk you through the essentials. We’ll also explain when you should put a Christmas cactus in the dark to coax out those much-loved holiday flowers. This advice can be tailored towards other types of holiday cactus too, but bear in mind the timings will be a little different for the Thanksgiving cactus and Easter cactus.

How Much Light Does a Christmas Cactus Need?

Christmas cacti are adaptable and will do fine in most homes, but they do have their limits. Ideally, they should get around 6 to 8 hours of bright, indirect light each day. If they don’t, they can start stretching towards the light, producing leggy growth as well as fewer flowers. To ensure they get enough light, it's worth investing in a plant light, such as the GooingTop LED Grow Light from Amazon.

On the flip side, putting them in direct sun for long spells can lead to other Christmas cactus problems, such as leaf burn.

Placing a pot near a sunny window usually works well, and many growers swear by east- or west-facing spots. That way, the plant gets enough light without being blasted by the strongest rays in the middle of the day. If in doubt, try holding your hand above the plant – if the light feels strong on your skin, it’s probably too much for the cactus as well.

How Does Light Affect Flowering?

Light levels play a big part in making a Christmas cactus bloom. For buds to form, the plants need long nights – roughly 12 to 14 hours of complete darkness – each day. Shorter autumn days usually do this for you, but if you’ve got lamps on in the evenings, the plant might not get the rest it needs.

Simply switching off the lights or moving the plant to a darker room overnight can make all the difference. If that's not possible, then place a breathable black grow bag over the top in the evening – these inexpensive Land Guard bags on Amazon will do the trick, and can then be used in the vegetable garden in summer.

Lower night temperatures – around 50 to 55°F (10 to 13°C) – give them another nudge. These two conditions together mimic what happens in the plant's natural habitat and will usually trigger buds just in time for the holidays. (I find a cool spare room works a treat if you have one.)

Use a digital room thermometer, such as the ThermoPro TP50 from Amazon, which also has a humidity monitor so you can keep an eye on levels. Christmas cacti thrive with 50 to 70% humidity.

Do Christmas Cacti Like Sun?

Yes and no. They like light, but not the kind that beats down all day. Bright, indirect light is their sweet spot. If they get too much sun, you’ll soon see the signs – red or purple tinges on the leaves or scorched patches. Move them somewhere softer and they’ll generally recover without too much fuss.

Don’t panic if you notice a few damaged leaves; most plants bounce back once conditions improve. Learn how to prune a Christmas cactus to deal with any unsightly foliage.

What Kind of Light Does a Christmas Cactus Need?

Think dappled or filtered. A sheer curtain is often enough to diffuse sunlight into the kind of soft glow a Christmas cactus appreciates. Alternatively, try adding some temporary protection in the summer, like the Schrling No Drill Cordless Light Filtering Window Shade, available on Amazon, which attaches to the glass with suckers.

Indirect sunshine not only prevents stress but also keeps growth even and healthy.

When Should You Put a Christmas Cactus in the Dark?

If you want to force blooms, start about 6 to 8 weeks before you want flowers. That means placing the cactus in complete darkness for at least 12 hours each night – many people use a closet or cover the plant with a box. This routine continues until buds form. It might sound fiddly, but it really does work, and the reward is a plant smothered in color right on cue.

How Should Light Levels Change Throughout the Year?

In spring and summer, Christmas cacti enjoy longer days and will put that extra energy into building roots and fresh foliage. Many people like to move them outside during warm weather, but only into a shaded corner of the patio or under a tree where they get bright light without the burn. A hanging basket under a tree is a classic trick – it keeps them happy and adds a splash of greenery outdoors.

As autumn comes around and the nights turn cooler, it’s time to bring them back indoors and start dialing down the light a little. This gradual shift helps reset the plant’s internal clock and sets the stage for winter flowering.

The Christmas cactus (Schlumbergera x buckleyi) is a beloved holiday plant that, while generally resilient and trouble-free, can sometimes suffer issues. At best, the most common Christmas cactus problems may result in a poor appearance or loss of flowers; but in the worst cases, plants may suffer a decline in health and untimely demise.

Whether your plant is experiencing issues with incorrect Christmas cactus care, disease, pests, or other problems, the sooner you pinpoint the most likely culprit, the quicker you can solve the issue and get your plant back to its blooming loveliness.

While the Christmas cactus is one of the most popular types of holiday cactus, the advice in this guide can be applied to other varieties. Thanksgiving cactus care and Easter cactus care are similar and the plants may be affected by the same issues.

How to Diagnose Christmas Cactus Problems

If your plant is dropping excess plant material, is discolored, fails to produce new leaves and flowers, or has leaves that are puckered or faded, it is stressed.

Many Christmas cactus problems can mimic other issues, so identifying whether you have difficulties with care, disease, or pests can be challenging and a process of elimination.

Take a step back to examine the plant. Firstly, evaluate the cultural care and soil situation. If the plant has correct light and water, and the soil is well-draining and sterile, you can probably move on to pests and disease.

Below we've outlined the key symptoms to spot and how to cure affected plants.

1. Lack of Flowers

Making a Christmas cactus bloom is a priority for most indoor gardeners. The succulents require a plant dormancy period to encourage flowering, which can be created within the home.

In October – about eight weeks before Christmas – move the plant to a slightly cooler spot if necessary. The optimal Christmas cactus temperature is between 60 and 68°F (15 to 20°C).

During the dormancy period, the plant must receive at least 13 hours of total darkness each night – cover it with a box if necessary.

In the daytime, the plant should receive bright, but indirect light. Pale stems and the failure to produce blooms are often a result of inadequate sunlight.

2. Limp and Wilting Cactus

Christmas cactus wilting – often followed by dropping leaves – is a common symptom of incorrect watering.

Christmas cactus watering is a delicate balance. If the soil is very dry, then underwatering is likely the culprit. Give the soil a good drenching and allow it all to drain through.

On the other hand, overly wet soil can result in root rot, which will cause wilting and often yellow leaves. The plant may also smell bad.

You need to act fast to save an overwatered Christmas cactus. Get rid of any standing water, then remove the plant from its container. If any stems appear to have gone soft, then prune them away. Rinse the plant's roots and allow it to dry out for a day on the counter. The following day, repotting the Christmas cactus will help it to recover. Avoid watering for a day or two before starting a new, more conservative watering regime.

In the future, check the soil before watering. Push your finger down to the knuckle to check, and only water when the top inch or so feels dry. If in doubt, invest in a soil meter to test moisture levels and avoid incorrect watering in the future.

3. Leaves Turning Purple or Red

If your Christmas cactus is turning purple or red, then it can be a sign something isn't right. A slight purplish hue to the leaves is normal, but a more noticeable color change may signal poor nutrition.

It is necessary to feed plants throughout the growing season, otherwise they are less likely to flower. The best Christmas cactus fertilizer to use between spring and summer is a balanced houseplant feed, diluted to half strength. Apply once a month at the time of watering. In the fall, you can either stop fertilizing or switch to a low-nitrogen product that won't impede flowering.

As well as using a general houseplant fertilizer, it may be helpful to occasionally feed Christmas cacti with Epsom salts – dilute one teaspoon (5ml) in one gallon of water. This is because the plants have higher magnesium needs than most plants. Apply once a month throughout spring and summer, but not at the same time as fertilizing.

If you have been regularly feeding your Christmas cactus but leaves are turning purple or red, then the plant may be rootbound or the potting soil may be depleted, preventing the absorption of nutrients. Repot into a container the next size up, using a suitable Christmas cactus soil mix, containing perlite or sand to aid drainage.

One other possible culprit of purple and red leaves might be excessive light levels. If the plant receives too much direct light during the summer months, then the leaves may take on a purple tinge. Move the plant to a place where it receives bright but indirect light.

4. Disease

Unfortunately, there are several Christmas cactus diseases that may pose a threat to your plant. The majority of these are fungal, although bacterial disease can occur.

Fungal diseases such as fusarium, pythium, and phytophthora all cause lesions and rot. Look out for discolored leaves, browning stems, mold, and spots. Rather than try to nail down which fungal disease is present, take steps that would eradicate any of these.

As a rule, if a rotting or fungal disease is present, you can try a fungicide applied to the soil as a drench. You could also remove the plant, trim away any diseased roots, disinfect a pot, and repot it in sanitized soil. If the plant continues to decline and become soft and rotten at the soil line, it probably can’t be saved.

Cultural care is key to preventing disease in these plants. A healthy plant will usually not develop disease issues unless the soil is infected or there is an infected plant nearby. Avoiding watering above the plant can keep any pathogen in the soil from splattering onto the plant. Water at the soil line with a soft stream of water.

Use sterile potting mix where possible, which will have killed any pathogens harbored therein. Provide adequate ventilation and airflow to prevent moisture build-up on the stems and leaves. Avoid injuring the plant which can lead to entryways for disease.

5. Root Rot

Christmas cactus root rot is caused by overwatering, and it can quickly prove fatal to plants. The disease may first present itself with yellowing and dropping leaves, but to diagnose the issue you need to check the roots.

Depending on the extent of the root rot, the roots will have begun to blacken, or be slimy with brown decay. The plant and soil will likely have an unpleasant smell.

If you catch root rot early, you might be able to save the plant by trimming and cleaning infected roots, allowing the plant to dry out, then repotting. However, if the disease has progressed, then it's likely a lost cause. If part of the plant appears healthy, then learn how to propagate Christmas cactus, take some cuttings, and discard the plant.

6. Yellow Leaves

A Christmas cactus with yellow leaves is frustrating as several causes can be behind the issue. It's usually a process of elimination.

The most serious culprits are root rot or disease, so check for these and act fast to treat plants where affected. When plants are overwatered, this will quickly lead to root rot.

While Christmas cacti like their roots to be fairly confined, if they are rootbound plants may struggle to take enough nutrients from the soil. Likewise, a lack of fertilizing may also be the issue.

Too much direct sunlight during the warmer months can give the leaves a yellow, lackluster appearance, so if that is the suspected cause, then move the plant to a spot where it receives bright indirect light.

7. Dropping Leaves

A Christmas cactus dropping leaves is usually caused by one of two issues. Too much moisture is the biggest culprit and is easy to spot if the shedding is accompanied by yellowing leaves.

As well as overwatering, too much moisture can be caused by poorly draining, impacted soil, so where all else fails repot the plant.

The other problem affecting leaves is incorrect temperature. Too much heat or cold can cause leaves to drop. In general, Christmas cacti thrive in temperatures of 70 to 80°F (21-27°C) during spring and summer, and around 10°F cooler over fall and winter.

Try to minimize sudden temperature changes, and avoid placing the plant close to air vents or heating outlets.

Some leaf drop is normal when bringing outdoor Christmas cactus plants back indoors after summer. They should soon recover with a little TLC.

8. Bud Drop

Buds falling off Christmas cactus plants is one of the most common issues to frustrate growers, resulting in the loss of flowers right before the finishing line.

Common culprits are under or over-watering, lack of humidity, temperature changes, drafty conditions, and excessive heat.

Incorrect lighting levels may halt the production of buds, so ensure the plant is receiving at least 13 dark hours each night during fall and winter.

Too much fertilizer may also be to blame, as it can force the plant to put on an abundance of blooms that it has to drop some to make way for more.

9. Flowers Wilting or Falling Off

Christmas cactus flowers falling off, usually following a brief period of wilting, is often caused by underwatering. While plants hate to have soggy roots, they do need moisture to thrive and flower.

Usually, the best method of watering Christmas cacti is to soak the soil when dry and let it drain through. However, it's best to avoid deep watering while the plant is flowering, as it can cause blooms to wilt and fall off. Avoid fertilizing at this time too.

A sudden temperature change may shock the plant causing flowers to drop, so avoid moving it in the build-up to blooming.

Another possible culprit is a lack of humidity. As tropical plants, Christmas cacti prefer a fairly humid environment. You can raise humidity for houseplants by placing the pot on top of a tray of pebbles filled with water – but don't let the soil sit in the water.

10. Pests

If you move your plant outdoors in the warm weather, you may be inviting several Christmas cactus pests to infest the plant. Mealybugs and scale are often found on outdoor cacti. Mealybugs show up as white, cotton-like masses in the leaf axils, while scale is a hard-bodied, oval to round, insect in various colors.

They can cause weakened plants, stunted growth, and in severe infestations, plant parts begin to die and fall away.

Spray with insecticidal soap every 7-10 days or rub the infected plant parts with a cotton ball dipped in alcohol to wipe them away. Soil or fungus gnats are common even indoors, especially when the soil is overwatered.

Holiday cacti are wonderful winter-flowering plants that are easy to care for, but Christmas cactus watering has to be done correctly for optimal health and seasonal blooms. New owners may wonder how often to water Christmas cactus plants. The answer will vary by the plant's size, location, ambient moisture levels, and soil type. These cacti aren’t desert specimens and have specialized watering needs to keep them happy and blooming.

Regular watering is a crucial aspect of Christmas cactus care. As with other types of holiday cactus, the right moisture balance is key to making a Christmas cactus bloom. If you aren't sure whether you have a Christmas cactus, Thanksgiving cactus, or Easter cactus, then you'll be relieved to know that their watering requirements are very similar.

In their native tropical rainforests of Brazil, Christmas cacti are epiphyte plants that grow in the crotches of trees or rocky crevasses. They receive their moisture from the humid air, rainfall, and morning dew dripping down from the tree canopy. In this way they are very different from their desert cacti cousins, who have a high drought tolerance and can go long periods without water.

How Often to Water Christmas Cactus Plants

How often to water a Christmas cactus is a common question. These plants prefer fairly high humidity and moist, although not soggy soil. The ideal Christmas cactus soil mix should be fairly peaty with vermiculite or perlite to help hold moisture.

In the winter the plant needs water every three or four weeks. But during the blooming period, it requires more frequent moisture and soil should not be allowed to dry out to encourage prolonged flowering. During the growing seasons of spring and summer, water the plant on average every two weeks.

This schedule is subject to soil type, where the plant is growing, and other factors. For example, if the plant is in garden soil, it will dry out more quickly and need more frequent watering. If the cactus is near a drying heating vent, it will also need to be irrigated more often.

While guidelines on how often to water a Christmas cactus are helpful, the best gauge is to use your finger to detect when the soil is dry a couple of inches (5cm) down into the soil.

How to Water a Christmas Cactus

While these plants like moderately moist soil, they cannot tolerate being waterlogged – overwatering leads to various Christmas cactus problems. Move the container to the tub or sink when you water. Remove the saucer and let all the excess water percolate through the drainage holes. It is good to soak the soil to let it evacuate excess salts that build up from fertilizing.

Alternatively, you can put the plant in the shower every month and add enough water to the soil surface that it percolates out in a plentiful supply.

Many municipal tap water supplies have chemicals and minerals that the plant cannot tolerate. They are sensitive to chlorine and lime which are often in our tap water. Rainwater, distilled, or filtered water are ideal. You may also opt to let the tap water sit out overnight to off-gas.

From late winter to late summer, feed plants monthly during regular watering. The ideal Christmas cactus fertilizer is a bloom formula houseplant feed or a half-strength water-soluble formula, such as 20-20-20 or 20-10-20.

How Much Water Does a Christmas Cactus Need?

The answer depends on how large the plant is and the container size. Larger plants will need much more water than young, small cacti. In large containers, they will need more than beginner nursery pots. The touch test is the most reliable gauge of whether the plant needs watering.

Overall, water until the moisture is leaching heavily from the drainage holes, then allow it to drain through. This will ensure the plant is not in soggy soil and will also help clean the soil of built-up salts.

When to Stop Watering Christmas Cactus

This plant likes to be evenly moist at all times. It should not be allowed to dry out completely. In the winter, after blooming, Christmas cactus plants will need much less water but they should still be irrigated every three or four weeks. During the growing season, they will need much more water.

If the plant is brought outdoors for the summer, winds and sun will dry out the container much more quickly. Such plants will need watering at least twice as much as plants housed indoors.

How to Spot and Avoid Over or Underwatering

An underwatered Christmas cactus will have dry soil to the touch even at the drainage holes. Look out for Christmas cactus wilting, shriveled and puckered leaves, and wrinkled stem segments. Plant parts can start falling off in extreme cases. Increase watering frequency and use the finger test daily to ensure the soil doesn't dry out too much.

If your plant is drying out too quickly, then learn how to repot a Christmas cactus and move it up a container size. Christmas cacti like to be a bit potbound but should be repotted every two to three years.

Watch out for Christmas cactus diseases in overwatered plants. Signs include soft stems, yellow leaves, and leaf drop. In the worst cases, the plant will rot at the soil line and roots could develop fungal disease. Christmas cactus root rot can quickly be fatal, so if you see any putrid, discolored, or otherwise damaged roots, prune them out with sanitized shears.

Overwatered Christmas cactus care often includes repotting. Before you repot, sanitize the container with 1 part bleach to 9 parts water. Use pasteurized soil if possible to avoid introducing pathogens that will thrive in moist soil.

Should I Mist My Christmas Cactus​?

Christmas cactus is a tropical plant that naturally grows in a humid environment – 50-60% is ideal. Occasional misting won't do any harm but has little effect on raising humidity for houseplants. Instead, invest in a houseplant humidifier or place a tray of pebbles filled with water beneath the container.

Plants also like warmth. The ideal nighttime Christmas cactus temperature is 60-65°F (15-18°C) with a cooler period of about 50°F (10°C) in October to encourage blooms in time for the holidays. Average room temperatures during the day will enable plants to thrive.

One of the most magical plants during the winter months is the holiday cactus. There are several varieties, each of which is fairly simple to propagate. Making a new plant provides an excellent opportunity to gift these beautifully flowering plants and give someone else the opportunity to enjoy the blooms in winter's dormant season. Learn how to propagate holiday cactus for a gift that will give year after year. 

Cactus lovers know there are Easter, Thanksgiving, and Christmas cactus. Their cheery flowers are a treat when hardly anything is in bloom in winter. Schlumbergera cuttings are how to propagate Easter cactus and its cousins. Just a few steps and the gardener is well on their way to producing baby cacti that will bloom in future years. Keep new cacti in a shady location in summer, bringing the plant in before temperatures become cool. 

Christmas Cactus Propagation

Christmas cacti are probably one of the most recognized of the holiday cacti. The plants are in the genus Schlumbergera, the same genus as the Thanksgiving and Easter cacti. Schlumbergera bridgesii is the full botanical name of Christmas cacti. They are native to Brazil and are true cacti, although not the desert varieties which are familiar to most of us. They live in tropical forests as epiphytes, growing in tree crotches high in the forest. The stems have scalloped edges and the plants bloom with bright red flowers from November to February. The pollen bearing anthers are purple-brown, unlike Thanksgiving cacti, which have yellow pollen. There are no true leaves, but the plant photosynthesizes through the stems. 

How to Propagate Holiday Cactus

Thanksgiving cactus propagation and Christmas cactus propagation starts with good stem cuttings. Schlumbergera cuttings need to be sourced from healthy plants, preferably taken in May to June. Pinch off stem sections, known as phylloclades, which include three to five segments. You could also cut off the phylloclades with a clean, sharp, sterile knife. Allow the cut end to callus. Place the cuttings outdoors in a shady location for a couple of days. Use clean containers and well-draining soil and plant cuttings 1 inch (2.5 cm.) deep. Moisten the soil well and then cover the entire container in a clear plastic bag, secured around the edges. 

How to Propagate Easter Cactus

Easter cacti have bounced around in a few different genera but have now settled in Schlumbergera. They bloom March through May with pink to red flowers. Easter cacti are grown in the same manner as Christmas and Thanksgiving cactus propagation. Place covered pots in bright but indirect light for several weeks. Keep the soil moderately wet. In around three or up to eight weeks, the cuttings will have formed roots. For faster rooting, dip the cuttings into rooting hormone prior to planting. Rooted cuttings can be potted together for an instantly full looking plant. Plants usually can be expected to bloom the next year. Give plants cooler nights and darkness for a month to initiate blooming.

As the holiday season draws near, thoughts turn to filling our homes with vibrant plants that add life to the winter months. Among the most popular indoor plants for the season are the holiday cacti: Thanksgiving cactus, Christmas cactus, and Easter cactus. Each variety offers a delightful way to mark the seasons with brightly colored blooms and unique leaf patterns.

Despite often being mistaken for one another, these holiday plants are distinct varieties with different characteristics – the most notable one being their blooming times. This is what makes them ideal gifts for their namesake holidays.

If you aren't sure what type of holiday cactus you have, then the good news is that Christmas cactus care and Thanksgiving cactus care are fairly similar as the plants are low maintenance. However, Easter cactus care can be a little trickier as the species is more temperamental.

With a bit of know how, it's easy to tell them apart and tailor their care. Get it right and these stunning seasonal plants will reward you with blooms year after year, brightening your home and warming your heart through the festive season and beyond.

Differences Between Holiday Cactus Varieties

Broadly termed Zygocactus, holiday cacti are not desert cacti, but rather succulents native to the tropical rainforests of Brazil. They are epiphyte plants that in the wild live on other plants and derive their nutrients from the surrounding soil debris, air, and water.

Christmas cactus vs Thanksgiving cactus is the most common confusion surrounding different types of holiday cactus as their bloom times are close and both belong to the Schlumbergera genus. The Easter cactus is also native to Brazil but is a member of the Rhipsalidopsis genus.

While all three varieties can be differentiated by their bloom period and flower formation, the best way to identify them is to look at the shape of their leaf segments – or cladodes. These segmented cladodes are linked together to form the drooping, branching habit we’ve come to expect from this species.

• Thanksgiving cactus has pointed, claw-like edges on segments.
• Christmas cactus has notched edges on segments that are smooth and rounded.
• Easter cactus has rounded edges with tiny bristles at the joints.

However, there are other differences that make these seasonal plants stand out from one another.

Thanksgiving Cactus

The Thanksgiving cactus (Schlumbergera truncata) typically blooms from mid-November to late December, aligning with the Thanksgiving holiday. It is often found in stores labeled as a “Christmas cactus” due to its similar appearance, but its pointed segments and earlier blooming time make it unique

Featuring jagged, toothed edges on its flattened stems, or segments, the Thanksgiving cactus also has stunning blooms in pink, red, or white, that grow horizontal to the stems. They have a more tubular shape compared to the other varieties and possess yellow anthers.

The Thanksgiving cactus is slightly more resilient than the other holiday cactus varieties, making it a great choice for indoor settings and table centerpieces.

Christmas Cactus

The Christmas cactus (Schlumbergera x buckleyi), with its gracefully drooping, rounded-edged segments, blooms later than its Thanksgiving counterpart, typically from mid-December through January. These delicate flowers almost always come in pink and have purple-brown anthers.

Unlike the Thanksgiving cactus, the segments of the Christmas cactus are rounded and smooth, giving it a softer, more classic succulent appearance.

Christmas cacti are highly popular for their ease of care and striking blooms, making them a favorite for holiday decor or as a unique host or hostess gift idea. They thrive in slightly cooler indoor temperatures, which can help to prolong their bloom period, making them a lovely choice for holiday arrangements.

Easter Cactus

The Easter cactus (Rhipsalidopsis gaertneri), or spring cactus, blooms later than both Thanksgiving and Christmas cacti, often producing flowers from March through May.

It has smooth, rounded leaf edges with no notches and fibrous stems. However, the Easter cactus' main attraction is its distinctive star-shaped flowers, which come in a variety of colors, including pink, red, and lavender. These beautiful blooms tend to open fully in the daylight and close at night.

Easter cacti are less commonly available during the winter months, as their blooming period aligns with spring, but their soft-hued flowers make them a refreshing sight when the winter cacti are out of season. Unlike the other holiday cacti, the Easter cactus prefers more humidity and moderate light levels.

Holiday Cacti Care Tips

Holiday cacti are relatively easy to care for, but understanding their needs can help ensure they thrive and bloom beautifully each year. Here are some essential care tips to keep your Thanksgiving, Christmas, or Easter cactus healthy and flowering:

• Light Holiday cacti prefer bright, indirect light. Direct sunlight, especially during warmer months, can burn their leaves. Place them in a spot that gets plenty of natural light without direct exposure, such as near a north or east-facing window.
• Temperature These plants thrive in cooler temperatures between 60-70°F (15-21°C) during the day and around 55°F (13°C) at night. Exposure to cool temperatures before the blooming season encourages bud formation. The ideal Thanksgiving and Christmas cactus temperature should be slightly cooler at night during fall to stimulate blooming.
• Watering Unlike desert cacti, holiday cacti are native to humid forests and require consistent moisture. Water thoroughly when the top inch of soil feels dry, but avoid letting the plant sit in water. Water less frequently in fall to encourage flowering, then resume regular watering once buds appear.
• Humidity Holiday cacti benefit from higher humidity levels, especially Easter cacti. If your home is dry, consider misting your plants occasionally or placing a tray of water nearby to raise humidity.
• Soil for Christmas cactus and other varieties should be well-draining. Choose a potting mix formulated for succulents or cacti, with added organic matter to retain moisture.
• Fertilize monthly with a balanced, water-soluble fertilizer during the growing season, typically from spring to early fall. Christmas cactus fertilizer needs are reduced in late fall as they prepare for their bloom cycle. Stop feeding holiday cacti around this time.
• Repotting Christmas cactus and Thanksgiving cactus plants is necessary every 2-3 years, ideally after blooming. This keeps their roots healthy and allows the plant to grow, though they do prefer to be slightly root-bound.

Encouraging Blooms

Encouraging holiday cacti to bloom on schedule can require a bit of timing and care. All three types of cacti are termed short-day plants, which means they need 12-14 hours of uninterrupted dark, cool conditions to encourage blooming.

Thanksgiving and Christmas cacti require around 6 weeks of short days to encourage flowering while Easter cacti need 8-12 weeks of short days to facilitate blooming; right around the Easter holiday.

Reduce watering in the fall, and keep the plant in a cooler area that is not artificially lit in the evening. This will help mimic their natural blooming cycle and trigger bud development.

Both Christmas and Thanksgiving cacti may rebloom a second time in the spring although not quite as vigorously.

The process can be repeated year after year to ensure holiday blossoming. In fact, since Christmas and Thanksgiving cacti can live for up to a century, some holiday cacti become treasured heirlooms, passed down from generation to generation.

Who would have thought that a cactus would be a representation of Christmas? The holiday generally invokes scenes of snow, firesides, and evergreen conifers, but certainly not cacti. The story behind the Christmas cactus reveals why it bears the name and shows that there are several other "holiday" cacti, as well.

Schlumbergera Plant History

Adding to the intrigue, the Christmas cactus origin is steeped in sultry, tropical temperatures in the country of Brazil. A plant in the Schlumbergera family, Christmas cacti are so named because of their flowering time in the Northern Hemisphere. In their home region, they flower in April to May and the common name has no meaning. In Europe, they are called crab cactus, a nod to their clawed limbs. There are six main species of Schlumbergera. Of these, several are designated as "holiday" cacti in commercial production. These bloom from September to February and are forced to bloom and sold as gift plants during the Thanksgiving and Christmas periods, hence the Thanksgiving cactus plant and Christmas cactus were named. The genus name is a tribute to Frederic Schlumberger, a French collector of exotic botanical species. The group of holiday cacti were discovered by Allen Cunningham in the early 1800s, and by the 1900s, there were several hybrids. These were adopted into the Christian holiday traditions due to their blooming times, which coincided with Thanksgiving and Christmas.

Botanical Christmas Cactus Origin

Investigating the history of Christmas cactus reveals a bit of a tangle. Many botanists insist that Schlumbergera x buckleyi is the original, true Christmas cactus. This hybrid has all but disappeared and is a treasure among collectors. The form Schlumbergera truncata is the parent of the majority of the holiday cacti available today. It is actually quite different from S. buckleyi, with an asymmetrical flower and wings on the ovary. It may be found in hues of white, pink, rose, and yellow, while the original Christmas cactus was white with a pale pink throat. There are also hybrids with more orange tones and even an Easter cactus, which blooms later in the season.

One Possible Story Behind the Christmas Cactus

A bit of research leads to a charming bit of Schlumbergia history. A Jesuit missionary known as Father Jose was trying to convert Bolivian natives. However, in spite of his good works and attempts to pass along the Word, he was met with failure. The native people appreciated his help but did not believe in the Christmas story he tried to convey. As he was praying at his crude alter on Christmas eve, he heard his congregants singing a hymn he had taught them. When he looked up, the children of the village were heading his way bearing plant stems decorated with beautiful flowers. These were the blooms of Schlumbergia cacti, which they gave to him to decorate the altar. Whether the story is true or not, it is illustrative and a sweet tale nonetheless.

With proper care, a Christmas cactus can thrive for decades. As its name suggests, the plant produces an abundance of cascading blooms that imbue a joyous, festive feel throughout winter. So when growers experience Christmas cactus buds falling off, it is hugely frustrating.

Though healthy plants will bloom dependably at this time, some may struggle to flower properly. Bud drop is one of the most common Christmas cactus problems, and as is usually the case, prevention is better than cure.

Below, we’ll explore this issue in greater detail, emphasizing the potential Christmas cactus care lapses that can cause buds to fall off, and how to prevent it from occurring in the future.

Another problem growers might face is Christmas cactus flowers falling off. It's a separate issue, but may have the same cause.

The advice in this article is applicable not only to true Christmas cactus plants (Schlumbergera x buckleyi), but the other types of holiday cactus, as Thanksgiving cactus care and Easter cactus care are very similar, and the plants are often confused.

Understand Christmas Cactus Flowering Habits

When a Christmas cactus is losing buds, it's helpful to gain a better understanding of the needs of the plant and its unique flowering habit.

Christmas cacti are succulents that reside in the deeply vegetated tropical forests of Brazil. They are epiphyte plants that grow on trees and rocks beneath a dense tree canopy, taking moisture and nutrients from their surrounding environment using aerial roots.

Species sold throughout the holiday season are often considered “short-day” plants. Making a Christmas cactus bloom requires a long period of darkness before the plant sets buds – at least 13 hours each night for eight weeks. This occurs naturally throughout winter when the day length is much shorter.

Other factors, like temperature and moisture, will also play a role in the plant’s ability to flower.

Why are Buds Falling off My Christmas Cactus?

Most Christmas cactus plants are sold straight from greenhouses where they have experienced strictly controlled lighting, moisture, and temperature conditions. Just moving them into your home can cause bud drop, as it is often a response to changes in the environment, but there may be other issues at work as well.

Growers will need to observe affected plants carefully and diagnose bud drop by following a process of elimination. Common culprits of Christmas cactus buds falling off include:

1. Watering Issues

Consistency with Christmas cactus watering is essential to the production of flowers. Growers will need to water potted specimens on a regular basis, making certain that the soil is allowed to dry fully between waterings.

Rapid or inconsistent fluctuations in moisture levels may lead plants to become stressed, resulting in poor or delayed bud set. Irrigation will be of special importance during periods of active growth and the time leading up to bloom in winter.

If you have neglected the plant and suspect underwatering is the issue, give the soil a thorough drench, then leave it to dry out before beginning a new watering regimen.

However, don't overcompensate by overwatering. Too much moisture can lead to root rot, which is one of the leading causes of houseplant death. Overwatered Christmas cactus care involves removing the plant from its pot, allowing it to dry out for a day or two, and then repotting.

In the future, check the soil for moisture every few days, pushing your finger down into the first inch or two. If it feels moist, leave it be; if it feels dry, then water. Always allow the water to drain through fully before returning the pot to its tray or outer container.

Consider buying a moisture meter, like this simple one from Amazon, to monitor the moisture level of your soil.

2. Lack of Humidity

As well as watering, check humidity levels. As tropical plants, Christmas cacti thrive in around 50-60% humidity, which is higher than the average home interior. They will tolerate slightly lower levels than this, but where the air is very dry, this can cause bud drop.

You can raise humidity for houseplants by using a small houseplant humidifier, mister, or by placing the pot on top of a tray of pebbles filled with water. You can get a humidity tray along with a variety of pebbles in all different colors from Amazon. Never let the soil or roots sit in the water.

3. Incorrect Temperature

Incompatible Christmas cactus temperatures – or sudden changes in temperature – are likely to affect plants' production of flowers.

While in the summer months, the cacti can thrive in slightly warmer temperatures in the 80s, they need cooler conditions of between 60-65°F (15-18°C) in the fall and winter. Temperatures within this range allow for optimal production of buds.

Unseasonally warm conditions, or sudden changes in the environment, can negatively impact growth, or send the plant into shock, causing sudden bud drop. The same can also be said of indoor plants positioned near ventilation or heating outlets, or situated in especially drafty spaces.

4. Light Imbalance

Christmas cactus light requirements remain among the most important factors influencing growth. Plants will thrive where they are able to receive bright, indirect light throughout the day.

Experienced growers often suggest positioning containers near an east or west-facing window to fulfill the plant’s needs best.

In the weeks leading up to flowering, Christmas cacti require long periods of darkness to initiate bloom. Starting in September or early October, ensure the plant is positioned in a room where it receives at least 13-14 hours of darkness each night.

This should occur naturally, as the day length continues to shorten through winter. Interruptions during this time can cause the plant’s failure to set buds. If necessary, put the cactus in a closet overnight, or cover it with a box or shade cloth (like this one from Amazon) at night.

During the day, the plant should be placed in bright light for the remaining 10 hours but avoid scorching sun from southern windows. Once buds have set and begun to open, the false lighting regimen can end.

5. Poor Soil Fertility

Depleted potting soils can lead to notable deficiencies in nitrogen, magnesium, and other elements essential to plant growth. Problems related to soil nutrient levels will generally manifest in the yellowing of foliage or the Christmas cactus wilting.

Especially stressed plants will continue to lose vigor over time, progressing to the loss of buds or complete failure to flower.

Repotting a Christmas cactus should provide the fresh injection of nutrients the plant needs. The ideal Christmas cactus soil is a mix of around two-thirds houseplant soil and one-third sand, perlite, or vermiculite to aid drainage. We recommend this Back to the Roots 100% Organic Succulent & Cacti Mix, available on Amazon.

6. Over Fertilizing

Going overboard with fertilizer can cause the plant to push out so many blooms that it drops some off to make room for the full development of the others. This abortive behavior is common in fruit plants, as well.

The ideal Christmas cactus fertilizer is a balanced houseplant feed – such as 20-20-20 – diluted to half-strength. Consider this organic succulent & cactus plant food from Amazon, specially formulated for cacti. This should be applied once a month between spring and the end of summer.

You also might want to occasionally apply Epsom salts, diluted in water, to meet the plant's high magnesium needs. This should be done no more than once a month in spring and summer, in a different week to fertilizing.

Once September arrives, either cease fertilizing or switch to a low-nitrogen formula, or you'll get lots of green growth but few flowers.

7. Disease

The worst-case scenario of bud drop is that it is a symptom of one of several possible Christmas cactus diseases. These issues are best diagnosed through careful observation, and by taking note of any change in the plant’s appearance. However, you need to act fast.

Fungal infections, which are often the result of improper watering, are most likely to impact flowering and the overall health of plants. But bud drop is usually accompanied by other symptoms such as rot, lesions, yellowing, browning, or mold.

Where disease is the likely culprit, apply a fungicide as a soil drench, then repot the plant, using fresh, sterile soil. Use the opportunity to prune your Christmas cactus of any diseased roots and plant sections.

If you catch the disease early, the plant may survive. However, if your Christmas cactus continues to decline, you may have to discard the plant. Learn how to propagate a Christmas cactus so you can try to regrow it from root cuttings.

8. Pests

If your plant spent the summer outdoors, then Christmas cactus pests may have hitched a ride when it moved back indoors.

There are different types of sucking insects that will feed on the plant’s sap, causing weakness, stunted growth, and bud drop. Common visitors to Christmas cactus plants include aphids, mealybugs, mites, scale, and whiteflies.

To rid your plant of pests, clean the leaves with a cotton ball dipped in alcohol, or apply a insecticidal soap spray every week. You can buy a commercial insecticidal soap spray, like this one from Amazon, or you can make your own. Neem oil is also very effective against most sap-sucking pests.

Known best for its impressive holiday blooms, the Christmas cactus (Schlumbergera x buckleyi) is cherished by growers for its cheerful winter displays. Indoor plants offer gardeners continued beauty year after year, perennializing with ease, and requiring only minimal care.

Still, those hoping to keep this interesting species as a houseplant will need to consider its growth needs carefully. Good Christmas cactus care starts with creating a healthy foundation for plants to flourish. Like all types of holiday cactus, this means meeting the species' specific soil requirements.

If you aren't sure whether you have a Christmas cactus, Thanksgiving cactus, or Easter cactus, then the good news is that their needs are very similar.

So, whether you're repotting Christmas cactus plants in fresh soil or learning how to propagate a Christmas cactus with the best potting mix, then read on for advice on creating the ideal growing medium.

Ideal Growing Requirements for Christmas Cactus

Native to Brazil, Schlumbergera is an epiphyte plant, meaning it grows on the trunks of larger trees and gains most of its moisture from the air. The Christmas cactus roots sink into decomposing leaves and debris resting on the sides of trees.

The plant draws some moisture from this makeshift soil, but because of its small volume and position high in the air, this soil dries out easily even with daily rainfall. This means that the best soil for Christmas cactus is extremely well-draining.

The growing medium should consist of a rich loam, high in organic matter. Experts often note that soil for Christmas cactus should be slightly acidic, allowing for a more favorable growing environment. You can check the pH of the soil with kits like this Rapitest Soil Test Kit from Amazon.

Potted Schlumbergera perform best when they are able to receive bright, indirect light. Indoors, this usually means that containers should be positioned near an east- or west-facing window. Regular Christmas cactus watering is also a must, making certain to avoid oversaturation.

What is the Best Christmas Cactus Soil?

The Christmas cactus will thrive in a variety of soil types. Though regular potting soils can be used, those specifically formulated to use with cacti and other succulent plants, such as the Espoma Organic Cactus Mix, 4Qt on Amazon, are often best. Such mixes are associated with better drainage and improved regulation of moisture, essential to the growth of certain plant species. The right potting mix will help make a Christmas cactus bloom over the holidays.

More experienced growers may choose to craft their own potting medium. Christmas cactus potting soils of this type are likely to include combinations of finished compost, sand, grit, moss, and perlite or vermiculite.

To make an easy potting mix, combine three parts of regular potting soil with two parts perlite or vermiculite. This will provide perfectly adequate drainage. If you’d like to take it a step further, mix equal parts compost, perlite or vermiculite, and milled peat.

These recipes can also be used for Thanksgiving cacti and Easter cacti.

Give Existing Christmas Cactus Soil a Boost

Over time, even the best potting soil for Christmas cactus plants can become depleted of nutrients. Sudden yellowing, and other noticeable signs of stress, are among the first indicators of poor soil fertility. Routine feeding can help to give the growing medium a boost, resulting in improved plant health.

The best Christmas cactus fertilizer is a well-balanced feed, specifically formulated for use with houseplants. Fast-acting liquids are generally considered best, aiding in the growth of foliage and development of flowers.

Especially tired soils may need to be replaced. This is best done when plants are repotted, once every two or three years. Plant it in a pot that provides just a little room for growth, and transplant it no more frequently than every three years.

Best Aftercare for Christmas Cactus Soil

Continued monthly feeding throughout periods of active growth will aid in keeping Christmas cactus plants both healthy and happy. Consistent watering, when soil has dried to the touch, will further help to meet the needs of the plant.

Water your Christmas cactus whenever the soil is dry – try not to let the soil dry out completely, but don’t let water stand in the pot or the saucer underneath, which could result in root rot. Drainage is much more important than water volume.

As noted, established specimens will require repotting with some frequency, as a means to support growth and prevent the loss of nutrients within the soil. Repotting will further aid in sustaining a strong root system.

Frequently Asked Questions

Does Christmas Cactus Like Acidic Soil?

Though it is possible to grow the plant in a standard mix, the best potting soil for Christmas cactus plants are those which are slightly acidic. This commonly includes those that have been specifically formulated for use with succulents, cacti, and species with similar needs. Other options include azalea or rhododendron mixes, as well as those rich in materials, like bark or moss.

Can I Use African Violet Soil for Christmas Cactus?

Many growers have found success with the use of African violet soil when growing Christmas cactus. Quality potting mixes of this type should demonstrate excellent drainage, and be slightly acidic in nature.

If you came into possession of a Christmas cactus (Schlumbergera x buckleyi) over the holidays, then it was likely bursting with blooms. But getting it to flower the next year can be tricky. As with most plants, fertilizing a Christmas cactus can make the difference between a stunning display of blooms or a lackluster show.

The perfect Christmas cactus fertilizer may be made or purchased and needs to be applied regularly throughout the growing period to fuel bud production.

An important aspect of Christmas cactus care is to suspend fertilizing at just the right time to ensure it flowers over the holidays. This coincides with shorter days and cooler nighttime temperatures, which are key drivers of bud formation. You should see buds start to appear around October to early November.

As well as Christmas cacti, there are a couple of other types of holiday cactus that tend to come into flower during certain holidays. Thanksgiving cactus care and Easter cactus care are broadly the same, so you can use this advice for those varieties too.

Best Fertilizer for Christmas Cactus

Fertilize Christmas cactus plants with a water-soluble, balanced bloom formula houseplant fertilizer, such as 20-20-20 (nitrogen, phosphorus, and potassium) or 20-10-20. Some growers suggest using African violet food.

Follow the fertilizer instructions for the amount to mix with water, but cut that in half. Full-strength fertilizer could burn Christmas cactus roots.

In addition to using a balanced fertilizer, Christmas cacti benefit from a monthly application of Epsom salts dissolved in water, due to the plants' high magnesium requirements. This 3lb bag of Epsom salts from Amazon will provide enough for the year.

When to Fertilize Christmas Cactus

Use a balanced fertilizer, like this Espoma Organic Cactus! Plant Food from Amazon, once per month in the spring and summer. Dilute the formula to half-strength and begin feeding at the start of spring until the end of August.

In the same period, supplement Christmas cactus food with Epsom salts once per month. However, do not apply in the same week as fertilizing. Dilute one teaspoon (5ml) of Epsom salts in one gallon of water.

In the fall, either stop fertilizing or switch to a low-nitrogen fertilizer, such as 0-15-0. The phosphorus will drive bud formation while limiting vegetative growth that could draw energy from flower production.

Once the plant has finished blooming, do not feed again until early spring. There is no need to fertilize in winter, as the plant is not actively growing.

How to Feed Them

Once per month, at the regular watering period, deliver the liquid fertilizer to the soil at half strength. Mix the fertilizer and water well and tip out any excess that leaches through the soil into the saucer. This will prevent the roots from sitting in too much moisture

Occasionally soaking the plant with water and letting excess salts flow out the drainage holes is necessary as excess salts can burn the roots. To do this, set the plant in the shower and drench the soil. Allow the pot to drain freely and the planting medium to dry out before watering anew.

Care Tips to Support Fertilizing

Regular feeding will keep a Christmas cactus healthy and promote bud development. But fertilizing alone does not guarantee flowers. Making a Christmas cactus bloom requires certain seasonal cues that mimic the plant's natural environment. They are tropical epiphyte plants native to Brazil, growing in the crevices of trees and thriving in warmth and humidity.

As well as looking out for common Christmas cactus problems, you need to support fertilizing by recreating the plant's native growing conditions as closely as possible.

• Light
  Christmas cacti set buds in fall during cooler days with shorter daylight hours. They need 12-14 hours of darkness to trick the plant into pushing out buds. In October, put the plant in a room that is not lit in the evening, or cover it with a box overnight. The rest of the time, plants benefit from bright indirect light.
• Temperature
  Daytime Christmas cactus temperatures of 70-80°F (21-27°C) are ideal during the spring and summer, with nighttime temperatures of 60-70°F (15-21°C). But the plant needs cooler temperatures in the fall and winter to encourage blooms. Ideal daytime temperatures this time of year are 60-68°F (15-20°C), with nighttime temperatures of 50-60°F (10-15°C). For an accurate reading, this digital indoor thermometer from Amazon will help.
• Watering
  Unlike desert cacti, holiday cacti live in tropical forests where they receive regular rainfall. These plants need to be kept moist but not soggy. Christmas cactus watering requirements are reduced in the fall when the plant is getting ready to bloom. Only water when the soil starts to dry out. Prevent the bottom of the pot from standing in water or root rot may occur, which is one of the most common Christmas cactus diseases.

• Humidity
  The Christmas cactus thrives with humidity of 50-60%. You can increase humidity for houseplants by placing the pot on a tray of pebbles filled with water.
• Repotting
  Eventually, the soil will release all it has to offer and the cactus will slowly starve. While the plants prefer a crowded environment, repotting a Christmas cactus is necessary every few years. A mixture of half potting soil and half sand or perlite is adequate.
• Soil
  To support fertilizing, Christmas cactus soil needs to be well-draining and slightly acidic. This enables the plant to uptake the nutrients delivered in the fertilizer. A potting mix pH of 5.5-6.5 is ideal.
• Pruning
  Prune Christmas cactus stem ends after blooming to encourage branching. You can propagate Christmas cactus by rooting these cuttings after allowing the edge to callus in a sand/soil mixture or pure vermiculite.
• Outdoors
  You can move a Christmas cactus outside in summer if you wish, but avoid harsh sunlight which can burn the stems.
• Pests
  Watch for common Christmas cactus pests including mealybugs or scale insects and combat them with a good insecticidal soap spray.

If you can provide these conditions to support fertilizing, then you will find the Christmas cactus to be one of the easiest, high-reward houseplants to grow, with year-end gifts to rival those holiday presents.

Christmas cactus (Schlumbergera bridgesii) is a popular winter-flowering houseplant that usually blooms over the holidays at the end of the calendar year. Varieties offer flowers in many different shades. Native to Brazil, Christmas cacti are epiphytes that grow in tree branches in rain forests. Since their stems hang down, they are perfect plants for hanging baskets. If a stem of your mature Christmas cactus is getting woody, it doesn’t mean that anything is amiss. That means that there is no reason to try fixing a Christmas cactus with woody stems. Read on for more information about woody Christmas cactus.

Woody Christmas Cactus Stems

A Christmas cactus that is cared for properly will last a long time, a quarter-century or even longer. Ideal Christmas cactus growing conditions include light shade in summer and full sunlight during fall and winter. Too much sun in summer pales or yellows the plants. Christmas cactus plants generally grow large with age. As the plant gets older and bigger, the base of the stems get woody. There is no need to think about fixing a Christmas cactus with woody stems. This is a perfectly natural condition and woody Christmas stems indicate a healthy plant.

Care of Old Christmas Cactus

If you buy or inherit an old Christmas cactus, it is likely a large plant. Proper care of old Christmas cactus includes cutting back overgrown branches and, sometimes, repotting the plant. One of the first steps in the care of old Christmas cactus is a good trim of the branches. When the branches become too long and heavy, they are likely to break off, so it’s better if you trim instead. This is especially true if the leaves look shriveled, thin, or limp at the ends. Trim the branches back by clipping at the segment joints. For overgrown cactus, cut each branch back by at least a third and up to three-quarters of its length. If a branch of the Christmas cactus is getting woody at the base, you can even cut it all the way back to the woody section. New green sections will grow from the wood.

Christmas cactus is relatively easy to grow, so if you notice Christmas cactus leaves dropping off, you’re justifiably mystified and concerned about the health of your plant. It isn’t always easy to determine what causes leaves dropping from Christmas cactus, but there are a number of possibilities. So why do Christmas cacti drop their leaves, you ask? Read on to learn more.

Why Do Christmas Cacti Drop Their Leaves?

Most frequently grown as a houseplant, it has the distinct property of blooming when the days are shortest, bringing color and brightness when most other plants are dying or settling in for the winter. This is all the more reason to be concerned when your Christmas cactus is losing leaves. Preventing and fixing leaf drop on Christmas cactus may be as simple as pinpointing the problem. When otherwise healthy leaves fall from Christmas cactus plants, there are a few possible reasons, with the following being the most common: Improper watering – When it comes to caring for Christmas cactus, overwatering is a big no-no. Although Christmas cactus requires more moisture than its desert cousins, too much water can cause the plant to rot – a common cause for leaves dropping from Christmas cactus. Although not quite so common, underwatering can also cause leaves to drop. As a rule of thumb, a Christmas cactus should be watered about once a week, or when the top of the soil feels dry to the touch. Water until moisture trickles through the drainage hole, then allow the pot to drain completely before placing it on the top. Don’t allow the soil to become bone dry, but never allow it to remain soggy. Water the plant sparingly during fall and winter. Poorly-drained soil – If your Christmas cactus leaves are falling off, it may also be caused by soil that is too dense or compacted. Christmas cactus requires porous, well-drained soil. If the soil is compacted or doesn’t drain well, it may benefit from repotting in a clean pot with fresh potting soil. A potting mix consisting of approximately 75 percent regular, good quality potting soil with 25 percent sand or perlite works well. Be sure the pot has a drainage hole. Temperature – Too much heat or cold may be to blame for Christmas cactus leaves dropping off. Christmas cactus doesn’t appreciate cold temperature. As a general rule, the plant prefers temperatures between 70 and 80 F. (21-27 C.) during spring and summer, and slightly cooler temperatures during fall and winter. Don’t allow temperatures to rise above 90 F. (32 C.). Cooler temperatures are beneficial while the plant is setting buds, but never below 50 F. (10 C.). Avoid sudden temperature changes and protect the plant from drafty windows and heat sources such as fireplaces or vents. If you’ve just bought your Christmas cactus or just moved it in from its summer spot outdoors, it’s probably experiencing a big change in environment. The shock of this change may make it drop a few leaves, and there’s not much that can be done about this. Light – Christmas cactus performs best in bright, indirect sunlight and may be damaged in bright, intense light, especially during the summer. One nice thing about a Christmas cactus dropping leaves is that these plants are very easy to propagate. What we refer to as “leaves” are really segmented branches. As long as they’re healthy looking, try planting your dropped branch in a new container - chances are good that it will take root and grow into a new plant.

With proper care, a Christmas cactus can live for up to a century but even these hardy plants aren’t without their share of pests. Luckily bugs in Christmas cactus are a rarity and generally not detrimental to the plant – although certainly they are an annoyance to the grower.

Like most common Christmas cactus problems, pests can be managed through a proper care routine, as a healthy plant is a resilient plant. While these plants are generally low-maintenance, following their specific Christmas cactus care requirements makes all the difference.

Christmas cacti are epiphyte plants native to Brazillian rainforests that grow on trees and get water and nutrients from the surrounding environment. In their natural habitat and as houseplants, they are fairly immune to pests; however, they can be afflicted with common pests such as scale, mealybugs, gnats, thrips, and spider mites.

In the event your plant becomes infested, what can you do? Firstly, take heart – most Christmas cactus insects are easily eliminated. Keep reading to learn how to get rid of common pests. This advice can also be applied to the other types of holiday cactus, as Thanksgiving cactus care and Easter cactus care are broadly similar.

Common Christmas Cactus Pests

Even a well-cared-for plant may become infested with pests, especially if your Christmas cactus lives outside for at least part of the year.

While some pests are obvious, others will present with other symptoms before you notice the cause, such as the Christmas cactus wilting, turning yellow, or dropping leaves. Growth may be stunted and you will find it difficult to make the Christmas cactus bloom.

Here are some of the most common Christmas cactus pests to look out for.

1. Fungus Gnats

Fungus gnats (Bradysia species), the bane of greenhouse growers, are the most common pest of Christmas cacti. While these tiny, flying insects, do not injure the plant their offspring larvae do. The small legless larvae feed on the roots and stems of cacti, leading to infection.

Fungus gnats can be controlled with pesticides specific to these pests. Adults are quite susceptible to most chemical controls. Surface sprays and soil drenches are effective at controlling larvae.

Nematodes can be purchased for use as control of fungus gnats as well. They seek out soil insects and eradicate them with no ill effects to the plant.

Insecticidal soap and sticky traps can also aid in the control of fungus gnats.

Otherwise, avoid overwatering, as gnats are attracted to soggy soil. Christmas cactus watering is a delicate balance and should only be done when the top layer of soil has dried out.

You can also replace the top couple of inches (5cm) of soil where the adult gnats lay eggs and their larvae feed on decaying plant material.

2. Thrips

Thrips (Frankliniella species) are another pest that preys on Christmas cacti. These tiny slender insects feed on young stems and flower buds. The damage caused results in stunted or distorted growth and Christmas cactus buds falling off. Both adults and their young can damage plants.

As well as contorted growing points, look for damage on leaves that appears as white or silver streaks. Heavily infested leaves will appear silvery and brown, and you may observe dark fecal spots.

You can treat the exposed parts of the plant with a natural insecticidal soap or neem oil spray. However, when young thrips hatch they drop into the soil, so you may want to use a systemic houseplant insecticide in the soil to eliminate the infestation.

3. Mealybugs

Mealybugs (Pseudococcus calceolariae, Planococcus citri and others) are an annoying pest, common on indoor plants. Although the tiny bugs on Christmas cactus are tiny, they are easy to spot by the protective cottony masses, which are usually seen at the joints of leaves and stems, or on the undersides of leaves.

The bugs, which suck the sap from the leaves, grow larger as they mature. If left untreated, they leave a sticky substance – honeydew – that attracts mold.

To remove mealybugs, pick them off with a toothpick or soft toothbrush. You can also use a cotton swab dipped in rubbing alcohol but be careful; too much rubbing alcohol may damage the leaves. Dilute it to a ratio of 1:3 of 70% rubbing alcohol to water. If all else fails, you may want to try a systemic insecticide formulated for indoor plants.

4. Root Mealybugs

Root mealybugs (Rhizoecus species) are small pests that feed on cactus roots resulting in yellowing, reduced growth, and eventual death of the plant. The infested roots become clotted with fuzzy, white masses of eggs and female mealybugs.

In the early stages, plants may remain symptomless as the infestation is below the soil line. However, stunted plant growth, wilting, or yellow leaves may be apparent.

The best control method for mealybugs is prevention. Systemic applications of insecticides such as soil drenches can aid in control but are not without risk. Be sure the plant container has adequate drainage and that no saucers are attached to the container as these may result in phytotoxicity. If you choose not to use chemical control, the best measure is to discard infested plants.

5. Scale

Scale insects (Coccomorpha) are tiny, dark brown, round to oval pests whose feeding results in stunted or weakened plants. Scales feed on the cladophylls, the flattened stems or branches of the cactus. They can be difficult to spot in the early stages, but severe infestations can result in yellowing, lack of growth, and plant death.

To treat minor infestations, you can pick off or gently scrub the scale from the leaves and stems. You can also wipe them off with an alcohol-soaked cotton swab or neem oil solution.

Severely infested plants may be treated with a soil drench using a chemical insecticide. Always use chemical controls according to the manufacturer’s directions.

6. Spider Mites

Spider mites (Tetranychidae) are so tiny, they are difficult to see with the naked eye. However, if you see fine webbing or fine speckles on the leaves, you can bet your Christmas cactus is infested with spider mites.

These pests are usually easy to resolve with regular application of insecticidal soap spray. Keep the leaves clean, as mites are attracted by dusty conditions.

7. Other Christmas Cactus Pests

If your Christmas cactus is kept outside for the summer – or even all year round in USDA hardiness zones 9-11 – then plants may become damaged by nibblers like deer, rodents, and rabbits. Even slugs and snails find Christmas cactus delectable.

If larger pests are a problem, you will need to protect the plant with a fence or other mesh cover, or bring it inside to a covered area.

As to slug and snail interest in Christmas cacti, the best way to thwart these pests is to raise their container up from the ground so these gastropods can’t feed on them.

Christmas cactus is a familiar plant that produces masses of colorful blooms to brighten the environment in the darkest days of winter. Although Christmas cactus is relatively easy to get along with, it isn’t uncommon to notice a Christmas cactus with yellow leaves. Why do Christmas cactus leaves turn yellow? There are several possible reasons for yellow Christmas cactus leaves. Read on to learn more about this frustrating problem.

Troubleshooting a Christmas Cactus with Yellow Leaves

If you notice your Christmas cactus leaves turning yellow, consider the following possibilities: Time to repot – If the container is packed tightly with roots, the Christmas cactus may be potbound. Move the Christmas cactus to a pot one size larger. Fill the pot with a mixture that drains well, such as two parts potting mix and one part coarse sand or perlite. Water well, then withhold fertilizer for a month after repotting a Christmas cactus. However, don’t rush to repot because this plant actually thrives in a crowded pot. As a general rule, don’t repot unless it’s been at least two or three years since the last repotting. Improper watering – Yellow Christmas cactus leaves may be a sign that the plant has a disease known as root rot, which is caused by excessive watering or poor drainage. To check for root rot, remove the plant from the pot and inspect the roots. Diseased roots will be brown or black, and they may have a mushy appearance or a musty odor. If the plant has rot, it may be doomed; however, you can attempt to save the plant by trimming the rotted roots and moving the plant to a clean pot with fresh potting mix. To prevent root rot, water only when top 2 to 3 inches (5-7.6 cm.) of soil feel dry to the touch, or if the leaves look flat and wrinkly. Decrease watering after blooming, and provide only enough moisture to prevent the plant from wilting. Nutritional needs – Christmas cactus leaves turning yellow may be an indication that the plant is lacking necessary nutrients, especially if you don’t fertilize regularly. Feed the plant monthly from spring until mid-autumn using an all-purpose liquid fertilizer. Additionally, Christmas cactus is said to have a high magnesium requirement. As such, some resources recommend a supplemental feeding of 1 teaspoon of Epsom salts mixed in one gallon of water applied once monthly throughout spring and summer. Stagger feedings and don’t apply the Epsom salt mixture the same week you apply regular plant fertilizer. Too much direct light – Although Christmas cactus benefits from bright light during fall and winter, too much sunlight during the summer months can give the leaves a yellow, washed-out appearance. Now that you know why leaves turn yellow on Christmas cactus, this problem need not be frustrating anymore.

Christmas cacti tend to show up in the stores in November. These succulents, with their segmented green branches and brilliant floral displays, are extremely popular houseplants and they are generally easy to care for. However, if you find yourself asking "Why is my Christmas cactus turning purple?” then your plant is telling you that something isn’t quite right.

Oftentimes, a purplish tint to your Christmas cactus leaves is normal but leaves turning noticeably purple or red can be a symptom of some common Christmas cactus problems. There are more than a few challenges that can result in purple leaves, usually caused by incorrect Christmas cactus care. Solving these issues is also key to making a Christmas cactus bloom.

Read on to learn about possible causes and solutions for reddish-purple Christmas cactus leaves. If you have one of the other types of holiday cactus, then you can also follow this advice, as Thanksgiving cactus care and Easter cactus care are very similar.

Why Is My Christmas Cactus Turning Purple?

A typical Christmas cactus has green foliage and red flowers growing from the tips of the branches. It’s this red/green combination that makes them so appealing as a holiday plant, especially since the flowers appear in late November or December.

However, if you see the segmented branches of your Christmas cactus turning red or purple, it definitely signals a health issue.

So, why is your Christmas cactus turning purple or red? There are more than a few possible reasons, and this reddish or purple tint seems to be the plant’s way of reacting to many different kinds of stress. The three main culprits are:

1. Lack of Nutrients

If you don’t fertilize your Christmas cactus regularly, then it may be lacking necessary nutrients. The plants do best when fertilized occasionally during the growing season – between early spring and late summer.

The ideal Christmas cactus fertilizer is a balanced houseplant feed diluted to half-strength. Apply it once per month as part of your Christmas cactus watering regimen.

Additionally, because Christmas cacti require more magnesium than most plants, it can help to provide a supplemental feeding of 1 teaspoon (5ml) of Epsom salts dissolved in one gallon of water. Apply the mixture once every month throughout spring and summer, but don’t use the Epsom salt mixture the same week you apply regular plant fertilizer.

2. Root Issues

Christmas cactus roots like to be fairly crowded, but if they get too packed in, they can lose their ability to upload nutrients and the plant may react by turning purple.

Learn how to repot a Christmas cactus the right way and do it every three or four years, moving it into a container one size larger. Christmas cactus soil should be well-draining, usually with sand, perlite, or vermiculite included in the mix.

When you do repot, take a careful look at the roots while they are exposed to check for tiny round nematode cysts. If there is a heavy infection of these Christmas cactus pests, the plants will become stunted, and the branches turn red-brown.

3. Light Issues

Despite their name, Christmas cacti are not desert dwellers that thrive in a hot, dry location. They are epiphyte succulents and thrive in indirect light. If you give them too little light, you may never get blossoms, but too much light, especially direct sunlight, can turn the segmented branches purple. Be especially careful if you move Christmas cactus outside in summer.

Moving the plant to a more appropriate location may prevent sunburn and solve the problem. Be sure the location is away from open doors and drafty windows. Similarly, avoid hot, dry areas such as near a fireplace or heating vent.

How to Prevent Purple Christmas Cactus Leaves

The principal reasons Christmas cactus foliage turns purple or red are all cultural care matters. You can prevent the purple hue by taking care to provide adequate nutrients, repotting the plant every three or four years, and keeping the cactus out of hot, direct sunlight.

The question of nematode cysts is slightly more complex since nematodes can enter your plant’s life through infected pots, potting soil, or any other plant materials. Buy from a reputable garden store and if you find nematodes in your garden, clean and sterilize all tools before and after you use them.

How to Turn a Christmas Cactus Green Again

It may be possible to return a Christmas cactus to its original green color, but don’t get your hopes up.

You should take every step possible to return your plant to a state of health. If the plant is purple because of inadequate nutrients, start regular fertilizer applications. If the plant is pot-bound, repot it into a slightly larger pot. If it’s been exposed to too much sun or heat, place it in a more appropriate location.

After that, wait and see. Your chances of success are greater if you catch the problem when the coloring first begins to change. Learn how to prune a Christmas cactus, and you can cut away the purple stems once the plant has suitably recovered.

And if the Christmas cactus won’t change back to green, keep in mind that some find the purple stems exotic and interesting.

As the seasons change and temperatures begin to rise, you may wonder: can a Christmas cactus live outside? While these popular holiday bloomers are most often kept indoors, they can, under the right conditions, thrive outdoors in the summer months – or even year-round, depending on your climate. But there are some important limitations and specific care requirements to keep in mind before moving your cactus beyond the windowsill.

Originally native to the cool, shady cloud forests of Brazil, Christmas cactus isn’t your typical desert dweller. It prefers dappled light, mild humidity, and warmth – but without extremes. That’s why much of the usual Christmas cactus care advice assumes an indoor environment. If you’re planning to move your plant outside, even just for the summer, understanding its environmental preferences is essential.

Like other types of holiday cactus – such as Thanksgiving and Easter cacti – the Christmas cactus has similar needs when grown outdoors. Much of this guidance also applies to their care. If you’re growing multiple species, it’s worth reading up on Thanksgiving cactus care and Easter cactus care, as they follow similar seasonal patterns and environmental preferences.

Where Can a Christmas Cactus Live Outdoors?

You can grow Christmas cactus outdoors year-round only in USDA hardiness zones 10 to 11, where winters are consistently mild and frost is rare. In all other zones, your plant should stay in a container so it can be moved back inside as temperatures cool. Once nighttime temperatures approach 50°F (10°C), it’s time to transition the plant indoors to avoid cold damage.

If your region allows for planting outdoors in-ground, choose a sheltered site with excellent drainage and amend the soil with compost and loose material. Otherwise, a hanging basket or portable container gives you far more flexibility – especially in climates with cold winters or unpredictable temperature drops.

Ideal Outdoor Conditions

Growing a Christmas cactus outdoors requires closely replicating the conditions of its natural environment. Here’s what to keep in mind:

Light

Christmas cactus needs bright but filtered light – think morning sun or dappled shade, like under a tree or a covered patio. Avoid the harsh midday sun, which can scorch its segmented stems. Plants placed in too much light will show stress through reddish or bleached leaves.

Temperature & Humidity

The ideal Christmas cactus temperature ranges from 60 to 80°F (15 to 27°C) during the day, with tolerances down to 45°F (7°C) at night. Anything below that risks damage. In drier climates, you’ll also need to boost humidity – misting the plant or placing it near a tray of water and pebbles can help.

Watering

Outdoors, the plant may dry out more quickly due to air circulation and heat. Water Christmas cactus when the top inch or two of soil feels dry, but never let it sit soggy. Use a container with excellent drainage, and avoid heavy soils that hold moisture too long, as Christmas cactus root rot is a real risk.

Soil

Christmas cactus soil is ideally slightly acidic and well-draining. A blend of potting mix, perlite, and peat moss works well. If planting outdoors, amend the soil with loose material and plenty of compost to improve aeration and drainage, and enhance fertility.

When to Bring it Back Inside

Knowing when to bring in a Christmas cactus from outside is key – too soon, and it misses out on helpful seasonal cues; too late, and cold stress or damage may occur.

If your plant is outdoors in a container, you’ll need to bring it back inside before overnight temperatures fall below 50°F (10°C). To minimize stress, move it indoors gradually, matching indoor light and temperature as closely as possible for the first few weeks. This transition period helps avoid bud drop or leaf loss as the plant acclimates.

Additional Outdoor Care Considerations

Outdoor plants will be exposed to more Christmas cactus problems than indoor plants:

• Pests: Mealybugs, scale, and spider mites are common. Inspect regularly and treat with neem oil or insecticidal soap.
• Slugs and snails: These pests love the plant’s fleshy segments. Use diatomaceous earth or copper tape as a deterrent.
• Sun damage: If stems begin to look dry, scorched, or change color, reassess sun exposure.

Planting a Christmas Cactus Outside

You might opt to plant the cactus in the ground if your region is frost-free and within the plant’s temperature range. The best time to plant outside is when the soil is warm and the plant has not begun to actively grow after the winter rest period.

Baby it a bit after planting, but do not fertilize for several weeks. Then, once established, feed it regularly through the growing season. The best Christmas cactus fertilizer is a diluted product such as 20-10-20, used every two to four weeks, avoiding winter feeding. Provide it enough water to keep the soil moist at the root level, but lightly dry on the surface.

You’d be hard-pressed to find a houseplant that offers more bang for your buck than a Christmas cactus. These easy-care plants light up your home with brilliant flowers during the holiday season, and can do this year after year for a century or more… as long as they don’t succumb to root rot.

Christmas cactus root rot is a fungal disease caused by improper watering or poor drainage. It is one of the most common and lethal Christmas cactus problems, but early treatment can save the plant.

Christmas cacti (Schlumbergera x buckleyi) are not weak or sickly plants in general. They are tropical cacti, native to South American rainforests, that grow as epiphytes in the shady branches of trees. Christmas cactus care is fairly straightforward and is largely centered around getting them to bloom. However, if these succulents receive too much water – whether through overwatering or as a result of heavy soil – they can quickly develop root rot.

As Christmas cacti are similar to the other types of holiday cactus, you can apply the below advice to Thanksgiving cactus and Easter cactus plants too.

What Does Root Rot Look Like on a Christmas Cactus​?

Inspect your plants regularly so you can spot the signs of Christmas cactus root rot as soon as possible. A wilted Christmas cactus with limp, sagging branches, sometimes yellow leaves, and a foul smell are obvious symptoms, but an inspection of the roots will confirm the diagnosis.

Gently tip the pot over and slide the rootball out into your waiting hand. If the cactus is affected by rot, the roots will display blackened tips. Depending on the severity of the disease, rotten Christmas cactus roots will be slimy with black or brown decay.

How to Save a Christmas Cactus From Root Rot

If you determine that your Christmas cactus has root rot, it's critical to act fast:

1. Remove the Soil
   The first step of overwatered Christmas cactus care is to remove the plant from its soil as quickly as possible.
2. Clean the Roots
   Dislodge some of the soil from the outside of the root clump, then rinse the roots under fresh running water. Ensure this is tepid rather than cold or hot, to prevent shocking the plant.
3. Cut Away the Rot
   Using sterilized pruners or sharp scissors, take off any darkened or affected roots.
4. Apply Fungicide
   Treating root rot with fungicide is an optional step that can help to stop root rot from spreading. For a natural solution, lightly dust cinnamon over the roots – but not too much or it could have a caustic effect.
5. Dry the Roots
   To help the plant dry its roots, put a few absorbent paper towels on a plate, then set the plant on it. Move it into a warm, airy location and let it dry overnight.
6. Repot the Cactus
   While the plant is drying out, learn how to repot a Christmas cactus correctly, then the next day, repot it in a clean container with fresh, light potting soil. Be sure the pot has drainage holes so the soil can drain freely. The best Christmas cactus soil includes sand, perlite, or vermiculite to aid drainage.
7. Wait Before Watering
   Don't add water for a further 24-48 hours, then wait until the soil dries completely before adding more water.

How to Prevent Root Rot in Christmas Cacti

It is rare to see Christmas cacti suffering from root rot in their native environments. Since they grow as air plants, their roots are not buried in soil. Potting your plant up in light, well-draining soil and allowing the soil to dry out completely between waterings, is the recipe for preventing root rot in these cacti.

In the quest to avoid overwatering your Christmas cactus, don't let it dry out too much. These plants are succulents, storing water in their puffy leaves. This makes it harder to tell if they need a drink. If you leave it so long the leaves start to wither, the plant will not be able to take up water at the normal rate. If you apply too much water at this stage, then you will end up with soggy soil, potentially leading to root rot.

A responsive Christmas cactus watering regimen will avoid this issue – every few days push your finger down into the soil. If the top inch feels dry, then water deeply and let it drain through before returning to its outer pot or saucer. Never let the plant stand in water.

Water sparingly during the winter months, but don't allow the potting mix to become bone dry. Place the plant in bright sunlight during fall and winter and in light shade during spring and summer. Apply Christmas cactus fertilizer once a month during spring and summer.

Will My Christmas Cactus Recover From Root Rot?

Rot is a deadly disease and once it progresses, the only option is to discard the plant and start fresh. However, if part of the plant is healthy, then not all is lost.

Before starting treatment, learn how to propagate a Christmas cactus from root cuttings. This will enable you to grow a new plant in case you are unable to save the original.

Does your cat think the dangling stem of a Christmas cactus makes an excellent toy? Does he/she treat the plant like a buffet or a litter box? Read on to find out how to handle cats and Christmas cactus.

Christmas Cactus & Cat Safety

When your cat eats a Christmas cactus, your first concern should be the health of the cat. Is Christmas cactus bad for cats? The answer depends on how you grow your plants. According to the ASPCA plant database, Christmas cactus is not toxic or poisonous to cats, but insecticides and other chemicals used on the plant may be toxic. In addition, a sensitive cat eating Christmas cactus may suffer an allergic reaction. Carefully read the label of any chemicals you may have recently used on the plant. Look for cautions and warnings as well as information about how long the chemical remains on the plant. Contact your vet if you have any concerns. Cats love the feel of their paws in dirt, and once they discover this pleasure, it's hard to keep them from digging in your plants and using them as litter boxes. Try covering the potting soil with a layer of pebbles to make it hard for kitty to dig down to the soil. For some cats, cayenne pepper sprinkled liberally over the plant and the soil acts as a deterrent. Pet stores sell a number of commercial cat deterrents. One of the best ways to keep the cat out of a Christmas cactus is to plant it in a hanging basket. Hang the basket where the cat can't reach it, even with a well-executed and carefully planned jump.

Christmas Cactus Broken By Cat

When the cat breaks stems off of your Christmas cactus, you make new plants by rooting the stems. You'll need stems with three to five segments. Lay the stems aside in an area out of direct sunlight for a day or two to let the broken end callus over. Plant them an inch deep in pots filled with potting soil that drains freely, such as cactus potting soil. Christmas cactus cuttings root best when the humidity is very high. You can maximize the humidity by enclosing the pots in a plastic bag. Cuttings root in three to eight weeks. Cats and Christmas cactus can live in the same house. Even if your cat isn't showing any interest in your plant right now, he/she may take an interest later. Take steps now to prevent damage to the plant and harm to the cat.

Christmas cactus is a striking plant with bright pink or red blooms that add some festive color around the winter holidays. Unlike typical desert cactus, Christmas cactus is a tropical plant that grows in the Brazilian rainforest. 

The cactus is easy to grow and a cinch to propagate, but Christmas cactus has some unusual attributes that may cause you to wonder what's going on with your plant. Let's learn more about roots growing from Christmas cactus plants.

Why Christmas Cactus Has Aerial Roots

If you notice root-like growths on Christmas cactus, don't be overly concerned. Christmas cactus is an epiphytic plant that grows on trees or rocks in its natural habitat. The roots growing from Christmas cactus are actually aerial roots that help the plant cling to its host. 

The plant is not a parasite because it doesn't depend on the tree for food and water. This is where the roots come in handy. Christmas cactus aerial roots help the plant reach sunlight and absorb necessary moisture and nutrients from leaves, humus, and other plant debris that surround the plant. 

These natural survival mechanisms can give you clues as to why your potted Christmas cactus is developing aerial roots. For example, low light can cause the plant to send out aerial roots in an attempt to absorb more sunlight. If this is the case, moving the plant into brighter sunlight may diminish the growth of aerial roots.

Similarly, the plant may develop aerial roots because it is reaching out to find more water or nutrients. Water the plant deeply whenever the top 1 to 2 inches (2.5-5 cm.) of potting soil feels dry to the touch. Water sparingly during fall and winter, providing just enough moisture to keep the plant from wilting.

Feed the plant once every month, beginning in late winter or early spring, using a regular houseplant fertilizer. Stop fertilizing in October when the plant is preparing to bloom.

Christmas cacti are common gifts around the holidays. They tend to bloom in the winter, with showy flowers present for friends and family to admire as they attend winter festivities. The presence of small children and pets at family functions reminds us that not all plants are safe. Is Christmas cactus toxic? Read on to find out and help protect your pets from any Christmas cactus toxicity.

Is Christmas Cactus Toxic?

The bright salmon to red flowers and intricate pads are characteristic of the Christmas cacti, which tends to bloom around Christmas and gives them their name. The plant is not a true cactus, however, but an epiphyte. It needs bright light and well-drained soil, with moderate water needs. To ensure blooming, withhold water in October and gradually resume again in November. Good news! Unlike many of the holiday plants, Christmas cactus toxicity is not damaging. Mistletoe, holly (berries), and poinsettia are also common during the winter holidays and do have some toxic components, but it is safe to have the Christmas cactus in your home. It isn't even spiny, so you don't have to worry about sharp pointy things hurting mouthy dogs and curious cats.

Care of Christmas Cactus Around Pets

Christmas cactus is native to Central and South America. They are classed as Zygocactus, a form of epiphyte that has a similar appearance to traditionally recognized cacti. Epiphytes don't need a soil based medium to live in but can survive in tree crotches and rocky depressions where organic material has collected and composted down to a rich humic base. Most Christmas cacti are sold in a soil medium which is well-draining. Care of Christmas cactus around pets is similar to that of any tropical plant. They require deep watering followed by allowing the top few inches (8 cm.) of soil to dry out before applying moisture anew. The key to achieving bright blooms each year is to allow the plant to dry out in fall and winter. Move the plant to where it receives bright light and ensure temperatures are fairly cool. Ideal temperatures for flowering are 50 degrees F. (10 C.). Apply a 0-10-10 fertilizer in October to early November and reapply in February. Although, it is best to train animals not to sample plants in the home, no harm will come to them if they want to try a flower or a bite of foliage. Christmas cactus and pets make perfect housemates as long as your animal doesn't overeat the plant and destroy its health. Christmas cactus and pets can coexist in harmony in the home but preventive measures on other holiday plants should be taken. Place plants, such as poinsettia, up high where animals can't reach them. If the family pet is especially persistent, spray the plant with cayenne pepper dissolved in water. The spicy taste will make Fido or Kitty think twice about approaching any plant and avoid poisoning but also safeguard the plant from teething damage and foliar death.

Christmas cactus is a long-lived plant with bright blooms that appear around the winter holidays. Normally, blooms last at least one to two weeks. If conditions are just right, the impressive flowers may hang around for seven to eight weeks. Although the plant is relatively low-maintenance, dropping or wilting Christmas cactus blooms are usually an indication of improper watering or sudden temperature changes.

Flower Wilt on Christmas Cactus

Christmas cactus bloom wilt is often caused by excessively dry soil. Be careful and don't over-correct, as watering a Christmas cactus can be tricky and too much moisture may cause more serious problems, such as stem or root rot, which are usually deadly. For most of the year, you shouldn't water the plant until the soil feels slightly dry, and then water deeply so the entire root ball is saturated. Let the pot drain thoroughly before replacing the plant on a drainage saucer. However, it's important to note that slightly different tactics are needed when the plant begins to bloom. During the blooming period, water just enough to keep the potting mix consistently moist, but never soggy or bone dry. Don't water deeply during this time, as soggy roots may cause blooms to wilt and drop. Don't fertilize the plant while it is blooming either. From October on through winter, Christmas cactus prefers cool nighttime temperatures between 55 and 65 F. (12-18 C) during the blooming period. Keep the plant away from cold drafts, as well as fireplaces or heat vents. Christmas cactus also needs relatively high humidity, which replicates its natural, tropical environment. If the air in your home is dry during the winter months, place the pot on top of a layer of pebbles in a plate or tray, then keep the pebbles moist to increase the humidity around the plant. Be sure the pot is standing on the moist pebbles and not in the water, as water wicking into the soil through the drainage hole can cause the roots to rot.

Christmas cactus diseases aren’t common but can quickly prove fatal. Fungal and bacterial diseases spread throughout the plant, and if treatment is not swift, those show-stopping holiday flowers will soon become a distant memory.

Like most Christmas cactus problems, diseases are often caused by poor or contaminated soil, overcrowding, overwatering, and generally poor Christmas cactus care. Left untreated, diseases may lead to deathly root or stem rot.

Our tips on identifying common diseases of Christmas cactus will help treat and prevent any incidents. If you have one of the other types of holiday cactus, you can also use this guide to treat those plants, as Thanksgiving cactus care and Easter cactus care are similar.

Common Christmas Cactus Diseases

Improper soil type, lack of ventilation, contamination, and overwatering can all lead to a fungal bloom. Several different types of fungi may cause problems on Christmas cactus plants, while bacterial disease may also be the culprit. Each of these diseases has slightly different symptoms.

1. Botrytis Blight

Also known as gray mold, botrytis blight is a common fungal disease in many plants that develops in cool, wet, or humid conditions. Look out for Christmas cactus flowers falling off after developing gray mold. Where plants are kept in particularly humid conditions, the stems may also be affected.

Keeping plants in a warmer location and providing air circulation can help prevent botrytis blight. To treat the disease, apply a homemade fungicide spray or soil drench, improve ventilation, and reduce humidity to prevent future outbreaks.

2. Necrotic Spot Virus

A common disease of impatiens and several other plants, necrotic spot virus can also infect Christmas cacti. The disease may be spread by thrips, which are one of the Christmas cactus pests to look out for.

Unfortunately, necrotic spot virus can be difficult to spot in the cactus and may remain symptomless. Yellow leaves, spotted plant material, or the Christmas cactus wilting are good indicators.

There is no treatment for the disease and it can spread to other plants. However, if you are not sure this is the issue, try isolating the plant and repot the Christmas cactus into a clean container with fresh potting mix. If things don't improve, then destroy the plant.

3. Fusarium

Fusarium has a broad range of plant hosts and leads to wilt and rot. In Christmas cacti, it can cause sunken reddish orange water-soaked lesions. Over time it can cause root and stem rot. A pinkish-white mold can develop at the soil line. The fungus is often found in soil and favors high temperatures and moist soil.

It is difficult to treat fusarium in plants, so if the disease is advanced, it's best to start afresh. However, if there is enough healthy-looking plant matter, you can try treatment. Remove all parts of the plant – roots and stems – that show signs of infection, sterilizing the pruners between each cut. Repot the cactus into fresh potting soil and apply a fungicide drench labeled for treatment of fusarium.

4. Phytophthora and Pythium

These diseases have similar symptoms. Both cause root and stem rot. Phytophthora causes reddish lesions on the stems and graying plant material. Pythium also produces lesions that lead to rot. Wet, warm conditions promote the fungal spread

You can attempt to treat these issues by cutting away any affected plant matter, repotting, and applying a fungicide listed for these diseases.

5. Erwinia Carotovora

Erwinia carotovora is a bacterial disease that causes soft rot in plant tissues. The lower parts of the stem are first infected and the disease progresses up to the terminal ends. The bacteria causes black, slimy lesions, wilting, and finally plant collapse.

Avoid overhead watering since the bacteria live in the soil and splash up onto the plant stems. There is no treatment for this disease and plants must be destroyed.

6. Basal Stem Rot

Basal stem rot, which generally develops in cool, damp soil, can be caused by more than one type of bacteria. It is easily recognized by the formation of a brown, water-soaked spot at the base of the stem. The lesions eventually travel up the stem of the plant.

Unfortunately, basal stem rot is usually deadly because treatment involves cutting the diseased area from the base of the plant, which removes the supportive structure. The best recourse is to start a new plant with a healthy leaf.

7. Root Rot

Many of the above diseases can cause Christmas cactus root rot, but there are other fungi present in the soil that can cause the roots to decay. The major causes are an overwatered Christmas cactus and compacted soil. Cultural adjustments can prevent any root rots which will kill the plant.

If you suspect a root rot, pull the plant from its container and examine the roots. If they are discolored, slimy, smelly, or have lesions, root rot is a suspect. If the disease hasn’t progressed too far, cut out infected roots and rinse the remaining roots free of the infected soil. Sterilize a container and repot the cactus, taking care not to overwater in the future.

Treating Christmas Cactus Diseases

Fungicides are not always effective against Christmas cactus diseases because specific pathogens are difficult to identify, and different pathogens require different products.

If the disease has progressed throughout the plant, then it is often best to discard it and start again. If there is an undiseased section of the plant, try taking some cuttings and learn how to propagate a Christmas cactus. But keep the cuttings away from your other plants and see how they go.

If you want to try to save the plant, first isolate it to avoid infecting your other houseplants, then the treatment is similar to root rot. Remove the plant from its pot, and trim away any diseased roots or plant matter. Let the plant dry out overnight before repotting in fresh potting mix in a sterilized container. A good Christmas cactus soil mix holds water but is well draining: try 1 part potting soil, 2 parts peat, and 1 part vermiculite or perlite.

How to Prevent Disease in Future

Christmas cacti have little in common with desert cacti. These tropical epiphyte plants are native to rainforests and can tolerate higher humidity and moisture. Although the climate is damp for much of the year, the plants' roots dry quickly because they grow in the branches and crevices of trees – not in soil. This means the plants need good airflow and well-draining soil. They should never sit in soggy soil, as it is a breeding ground for harmful pathogens.

Avoiding overwatering and overhead watering can prevent many common Christmas cactus diseases. The plants like to be kept moist but the soil should never be so soggy it would leak water if you press it in your hands. It should just gently keep its shape when pinched.

Christmas cactus watering is only necessary when the top 2 inches (5cm) of the soil feels dry. Do not leave the plant sitting in a saucer of water, as it will keep the roots too wet. Water sparingly during the winter, but never let the potting mix become bone dry.

In a greenhouse setting where high humidity is the norm, try using a fan to increase airflow.

Use sterilized or pasteurized soil when repotting Christmas cactus. Sterilize plant containers prior to planting with 1 part water to 9 parts bleach. At the first signs of a fungal disease, apply a fungicide to the soil as a drench. This may help prevent the spread of the disease in combination with good cultural practices.

Certain cultural practices such as watering overhead can encourage fungal diseases harbored in the soil.

When you think of cactus, you probably envision a desert with heat wavering vistas and blazing sun. You aren't too far off the mark with most cacti, but the holiday cacti actually flower better in slightly cooler temperatures. They are tropical plants that need slightly cooler temperatures to set buds, but that doesn't mean that Christmas cactus cold tolerance is high. Christmas cactus cold damage is common in cold, drafty homes.

Christmas Cactus Cold Hardiness

Holiday cacti are popular houseplants that bloom around the holiday in their name. Christmas cacti tend to flower around the winter months and produce bright, bountiful, pink blooms. As exterior plants, they are only hardy in USDA zones 9 to 11. How cold can Christmas cactus get? Cold hardiness in Christmas cactus is greater than in some cacti, but they are tropical. They can't tolerate frost, but they need cold temperatures to force blooms. As a tropical plant, Christmas cacti likes warm, balmy temperatures, moderate to low moisture levels, and bright sun. It likes to be warm, but you should keep the plant away from extremes such as drafts, heaters, and fireplaces. Perfect nighttime temperatures range from 60 to 65 degrees F. (15-18 C.). To force bloom, place the cactus in a cooler area in October where temperatures are about 50 degrees F. (10 C.). Once the plants are in bloom, avoid sudden temperature fluctuations which can make Christmas cacti lose their flowers. In summer, it is completely fine to take the plant outdoors, somewhere with dappled light initially and shelter from any wind. If you leave it outside too far into fall, you can expect Christmas cactus cold damage.

How Cold Can Christmas Cactus Get?

To answer the question, we need to consider the growing zone. The United States Department of Agriculture provides hardiness zones for plants. Each hardiness zone illustrates the average annual minimum winter temperature. Each zone is 10 degrees F. (-12 C). Zone 9 is 20 to 25 degrees F. (-6 to -3 C.) and zone 11 is 45 to 50 degrees F. (7-10 C.). So, as you can see, the cold hardiness in Christmas cactus is fairly broad. That being said, frost or snow is a definite no-no for the plant. If it is exposed to freezing temperatures for more than a quick nip, you can expect the pads will be damaged.

Treating Christmas Cactus Exposed to Cold

If the cactus is out too long in freezing temperatures, the water stored in its tissues will freeze and expand. This damages the cells inside the pads and stems. Once the water thaws, the tissue contracts but it is damaged and doesn't hold its shape. This results in limp stems, and eventually dropped leaves and rotten spots. Treating Christmas cactus exposed to cold requires patience. First, remove any tissue that appears to be badly damaged or rotten. Keep the plant lightly watered, but not soggy, and place it in an area around 60 degrees F. (15 C.), which is moderately warm but not hot. If the plant survives six months, give it some houseplant fertilizer that has been diluted by half once per month during its growth months. If you put it outside the next summer, just remember Christmas cactus cold tolerance doesn't extend to freezes, so get it inside when those conditions threaten.

Article summary: Unlike desert cacti, Christmas cactus thrives in more humid conditions and needs consistently moist, well-draining soil. Repotting should be done after flowering has finished, in late winter or early spring, and only every three to four years, as plants bloom best when slightly rootbound. Use a lightweight, free-draining potting mix and move the plant into a container only one size larger to reduce the risk of root rot.

Christmas cactus is a jungle cactus that prefers humidity and moisture, unlike its standard cactus cousins, which require a warm, arid climate. A winter-bloomer, Christmas cactus displays flowers in shades of red, lavender, rose, purple, white, peach, cream, and orange, depending on the variety.

These prolific growers eventually need to be repotted.

Repotting Christmas cactus isn't complicated, but the key is knowing when and how to repot a Christmas cactus.

When to Repot Christmas Cactus

Most plants are best repotted when they display new growth in spring, but Christmas cactus repotting should be done after blooming ends and the flowers have wilted in late winter or early spring. Never attempt to repot the plant while it is actively blooming. Don't rush to repot Christmas cactus because this hardy succulent is happiest when its roots are slightly crowded. Frequent repotting can damage the plant.

Repotting Christmas cactus every three to four years is usually adequate, but you may prefer to wait until the plant begins to look tired or you notice a few roots growing through the drainage hole.

Often, a plant can bloom happily in the same pot for years.

How to Repot a Christmas Cactus

Here are some Christmas cactus potting tips that will help you find success:

• Take your time, because repotting a Christmas cactus can be tricky. A lightweight, well-drained potting mixture is critical, so look for a commercial mix for bromeliads or succulents. You can also use a mixture of two-thirds regular potting soil, like this Espoma Organic Potting Soil Mix from Amazon, and one-third sand.
• Repot Christmas cactus into a pot only slightly larger than the current container. Be sure the container has a drainage hole in the bottom. Although Christmas cactus likes moisture, it will soon rot if the roots are deprived of air.
• Remove the plant from its pot, along with the surrounding soil ball, and gently loosen the roots. If the potting mix is compacted, gently wash it away from the roots with a little water.
• Replant the Christmas cactus in the new pot so the top of the root ball is about an inch (2.5 cm.) below the rim of the pot. Fill in around the roots with fresh potting mix and pat the soil lightly to remove air pockets. Water it moderately with something like this Watering Can for Indoor Plants from Amazon.
• Put the plant in a shady location for two or three days, then resume the plant's normal care routine.

If your Christmas cactus is looking a bit peaked, the most likely cause is overwatering. While all plants need moisture to survive, overzealous watering can lead to serious issues like root rot. If you suspect you are dealing with an overwatered Christmas cactus, then you need to act fast to dry out the plant and restore it to blooming vitality.

Christmas cacti (Schlumbergera x buckleyi) are low-maintenance tropical succulents. While they require watering more often than desert cacti, they prefer being slightly underwatered rather than overwatered. Growers often overwater their plants after a period of neglect to “perk” them up, or they may just have a heavy hand with the watering can.

Overwatering is one of the classic Christmas cactus problems, so don't feel too bad if your plant starts exhibiting symptoms. However, early diagnosis is vital, and you will need to change your Christmas cactus care routine, to prevent reoccurrence.

Follow the below advice to bring plants back from the brink. In addition, if you have overwatered one of the other types of holiday cactus, then you can follow this advice to save them, as Thanksgiving cactus care and Easter cactus care are broadly the same.

Dangers of Overwatering

Christmas cactus watering is a delicate balance, with both under and overwatering causing issues for plants. However, overwatering is a bigger problem. Any cactus that has been allowed to sit in a saucer full of water is likely to have its health reduced.

If left unchecked, an overwatered Christmas cactus can develop crown rot or root rot. These diseases are serious and it may not always be possible to save the plant.

Perhaps most disappointing for growers is that making a Christmas cactus bloom will be almost impossible.

What Does an Overwatered Christmas Cactus Look Like?

An overwatered Christmas cactus will show obvious signs of distress. Check for wilting, leaf drop, yellow foliage, red or black legions, and soft, mushy stems. Where root rot or one of the other common Christmas cactus diseases is present, these symptoms may be accompanied by mildew or fungal bodies on the soil surface.

If the disease has progressed, remove the plant from the soil; the evidence will be in black or brown, mushy, and foul-smelling roots.

All of these signs are bad. They mean your plant is in trouble and you need to take steps to repair the situation if it's not too late.

How to Save an Overwatered Christmas Cactus

A Christmas cactus that has been drenched for some time may be past saving, so before treating your plant, learn how to propagate a Christmas cactus from root cuttings, so all is not lost if it does not recover.

If you discover the problem in time, there are some steps to take to help your plant rebound:

1. First, remove the plant from its container. Rinse the roots to get rid of any soil or fungus so you can get a good look at them. If they are black in color and give off a fetid odor, the plant is probably not saveable.
2. If the roots still look fairly good, remove any that look bad with some clean, sharp scissors. Also, remove any stems that are rotten at this time.
3. Let the plant dry out for a day on the counter.
4. The next day, repot the Christmas cactus in clean, well-draining soil in a container with adequate drainage holes.
5. Place the cactus in an area that gets 6-8 hours of sun per day.
6. Let the new soil stay dry for a day or so before beginning a regular water regimen.

Avoiding Overwatering

Preventing an overwatered Christmas cactus is simple if you water on demand, rather than on a schedule. Every couple of days, push your finger into the soil – if the top inch or so feels dry, then it's time to water. If you find it difficult to know for sure, then invest in a soil moisture meter.

Water generously, allowing the excess water to fully drain through before returning the cactus to its saucer or outer pot.

If the saucer or outer pot looks moist a day after watering, dump the excess water to prevent moisture gnats and keep the roots from rotting.

To prevent overwatering, it's also important that the potting mix is well-draining. The ideal Christmas cactus soil mixes in sand, perlite or vermiculite to aid drainage.

Overwatered vs. Underwatered Christmas Cactus

In fear of overwatering your Christmas cactus, don't err too much on the side of caution and risk underwatering. Neither over- or underwatering a Christmas cactus will make it happy.

An underwatered Christmas cactus will likely have puckered or wrinkled foliage. Leaves may turn brown and drop from the plant. If you touch the leaves, they will feel flat, not plump and fleshy as a healthy Christmas cactus would.

Because the plant’s common name includes the term “cactus” many growers think the plant needs little to no water like other cacti. The fact is that Christmas cacti are not true cacti. Rather, they are epiphyte plants also categorized as succulents. Their fleshy leaves do contain some water, but the plant still needs water at its roots.

Sometimes, growers, in a panic after realizing they’ve forgotten to water in some time, drench the cactus. This is problematic as the plant's vessels will have shrunk, decreasing their capacity to absorb water. Overwatering after a period of underwatering is a quick recipe for disaster.

Christmas cactus wilting woes are all too common for people who pick up this festive plant on a whim without fully understanding its care needs. While it is not a true cactus, the Christmas cactus (Schlumbergera x buckleyi) is a succulent from warmer climates and requires particular conditions to thrive as a houseplant.

Drooping is one of the most distressing Christmas cactus problems for growers, who watch on while their cherished plant withers away, losing vitality and its ability to bloom, heading towards an early demise.

Bear in mind that the Christmas cactus does have a natural arching form, with stems cascaading over the sides of pots. However, it is easy to spot the difference between a healthy and distressed plant. Healthy plants have lush, verdant leaves and are able to flower, while a sick Christmas cactus will be lackluster, off-color, limp, and possibly dry and wrinkled.

Fortunately, Christmas cactus care is fairly easy, and troubleshooting the problem is simple. The advice can also be applied to the two other main types of holiday cactus, as Thanksgiving cactus care and Easter cactus care are very similar.

Here are some potential causes for a limp Christmas cactus and their solutions.

Why Are the Leaves on My Christmas Cactus Limp?

Native to South American tropical rainforests, the Christmas cactus is an epiphyte plant that grows in the crevices of trees and rocks, getting its moisture and nutrients from surrounding moss, humus, and plant debris.

If the indoor conditions aren’t right, you’ll end up with a Christmas cactus that's limp and wrinkled before getting to enjoy its holiday blooms.

When deciding how to revive a wilting Christmas cactus, it's important to first diagnose the likely culprit. Follow a process of elimination, starting with the most common causes.

1. Overwatering

This is the most likely cause of wilting and drooping. Christmas cactus watering is a delicate balance and it’s very easy to harm plants by overwatering or poor drainage. Once the roots die from standing in soggy soil, they cannot take up water, and the leaves wilt. As well as wilting, the issue may be accompanied by yellowing and dropping leaves.

If you have overwatered your plant, avoid watering it until the soil has dried. If the soil is very soggy or the roots show signs of rotting, overwatered Christmas cactus care involves removing the plant, letting it dry out, and repotting it in a fresh potting mix.

The ideal Christmas cactus soil is a mix designed for succulents. We recommend this Back to the Roots 100% Organic Succulent & Cacti Mix, available on Amazon. Alternatively, you can make your own by blending three parts potting soil with two parts sand, vermiculite, or perlite, to aid drainage.

Repotting a Christmas cactus is usually only necessary every few years, but even if the soil is not soggy, refreshing it may resolve the issue. Bear in mind the plant likes its aerial roots to be confined, so only move up to a slightly larger container, or clean and reuse the existing pot.

2. Underwatering

A limp Christmas cactus may also be caused by a lack of water. Owners often assume they are true cacti that can tolerate drought conditions. This isn’t true. Too little water and humidity can cause the stems and leaves to droop.

If underwatering is the issue, soak the soil, letting the water run through the drainage holes. Water again in a day or two.

In future, every few days, push your finger into the soil down to the knuckle to feel for moisture. Alternatively, use a moisture meter, like this simple one from Amazon, to monitor the moisture level of your soil.

3. Salt Accumulation

If your plant gets adequate water and has good drainage, the issue could be salt accumulating in the soil. This is most likely an issue in areas with high salt content in the water. Look for a white crust buildup on the pot or soil as a sign.

Consider repotting in a fresh potting mix. In the future, you can avoid salt accumulation by using filtered water. Also, avoid watering the plant by setting the container in water and letting it soak up water from the bottom. This method tends to increase salt accumulation compared to top-down watering.

4. Too Much Light

If your Christmas cactus drooping is accompanied by scorched leaves, too much sunlight could be the culprit. These plants grow naturally in shaded areas, so a lot of direct, bright light can harm them. If you have scorched leaves, move the Christmas cactus to an area that gets some sun protection, especially in the afternoon.

Another good solution is to stick on a self-adhesive sheer curtain at the window, like this Sovtfides one, to protect plants during the summer months.

5. Diseases

Certain Christmas cactus diseases cause wilting and may affect plants. Root rot is the most common disease, usually caused by overwatering and standing water on the roots.

Unfortunately, root rot isn’t necessarily treatable. If there are only small areas of rot, you may be able to trim off those roots and repot the plant. It’s better to prevent root rot with good drainage and an appropriate potting mix.

Christmas Cactus Fixers

Will a Droopy Christmas Cactus Recover?

If you catch the problem in time and take steps to save your Christmas cactus, it can recover. Bear in mind the stress the plant has experienced may result in this year's buds falling off Christmas cactus plants. However, you can expect an outstanding show next winter – or possibly in the spring – if you follow the guidance to making a Christmas cactus bloom.

Unfortunately, if the roots are completely or almost completely rotted from standing water, the plant is unlikely to recover. The good news is that if you know how to propagate Christmas cactus, you have a good chance of regrowing the plant from root cuttings, allowing it to live a new life through its descendants.

Christmas cacti are popular festive plants that bloom during the holidays. While they are fairly low-maintenance, they might occasionally require a light trim. Learning how to prune a Christmas cactus will help it grow fuller and bushier, resulting in more blooms in the future.

Because Christmas cactus care is generally easy, it is not uncommon for plants to grow quite large. While this is lovely to see, it can create problems for a homeowner with limited space. So whether you want to reduce the size of your plant or just keep it looking its best, knowing how to trim a Christmas cactus the right way will make all the difference.

You can also use this advice for the other types of holiday cactus, as Thanksgiving cactus care and Easter cactus care are the same when it comes to pruning.

Do I Need to Prune a Christmas Cactus?

Christmas cactus clipping isn't strictly essential but it can be helpful to improve the appearance of a leggy plant or reduce its size.

Pruning a Christmas cactus offers another little bonus as well. The segments you remove from the plant can be easily propagated into carbon copies of the parent plant. Learning how to propagate a Christmas cactus will provide a fantastic source of holiday gifts for family and friends.

Even if your plant looks phenomenal and doesn’t necessarily require any pruning, you can take cuttings every 3-5 years to produce an abundance of healthy young plants.

When to Prune

Timing does matter here. You don’t want to prune the plant before it blooms since you won’t have the joy of seeing your plant in its full glory. So, the best time to prune a Christmas cactus is after blooming.

Once the plant has finished flowering, it will go into a rest period until mid-spring, at which time it will actively begin growing again. Prune the plant during this rest period. Trimming at this time will also encourage the plant to branch out, which means it will grow more of its distinctive stems.

If you're repotting a Christmas cactus, this is also a good time to perform a light prune, but don't go overboard and risk stressing the plant.

If you missed the optimal pruning window, you can still clip the plant any time until the end of spring – any later may impact making a Christmas cactus bloom.

How to Prune a Christmas Cactus

Pruning a Christmas cactus couldn't be easier. Identify which segments you wish to remove, then simply pinch or gently twist them. If they are of a larger size, you may need to snip them off with some clean shears. Twist or cut between leaf segments, at the narrow joint.

Deciding how much to cut back a Christmas cactus is key to success. If you are pruning to reduce the size of the plant, you can remove up to a third of the plant each year. Otherwise, be judicious with your pruning and only trim the end one to two segments

Sit back and have a good look at the plant from all angles. Determine where you would like additional branching and remove a segment from that area. Don’t remove too many segments which can damage or kill the plant. Each segment you remove will encourage branching.

If you hard prune, you will end up with a rather scruffy-looking plant for a while and if you cut too much of the plant you can kill it.

How Often Should I Prune?

There should be no need to prune the plant any more than once a year unless it becomes diseased. A healthy Christmas cactus shouldn’t need significant pruning more than every 3-5 years.

If your plant has signs of one of the common Christmas cactus diseases, you can prune affected limbs out at any time. If your plant is gangly and you want to encourage branching, prune it during its rest period – after it has flowered and before active regrowth in March or April.

Christmas cactus (Schlumbergera x buckleyi) is a popular seasonal plant prized for its striking winter flowers. The succulents can endure for decades, so knowing how to get a Christmas cactus to bloom year after year is of prime importance to growers.

While Christmas cactus care is fairly easy, the plants may need a little encouragement to reflower, but it's well worth the trouble. By creating the right growing conditions, it's possible to not only force rebloom in time for the holidays, but again a few months later.

In addition to the Christmas cactus, with its white or bright pink flowers, you can also use this advice for the other types of holiday cactus, to help them rebloom. Thanksgiving cactus care and Easter cactus care are very similar, although the plants have slightly different bloom times.

Discover how to make a Christmas cactus bloom so you can enjoy a spectacular holiday show year after year.

What Makes a Christmas Cactus Bloom in the Wild?

Christmas cactus plants are different from desert cacti. Native to the rainforest in Brazil, they are epiphyte plants that grow in trees or between rocks and gather water and nutrients from the surrounding environment. Unlike other cacti, they need a lot of moisture, warmth, and indirect or filtered light.

In its natural setting, Christmas cactus flowers at the end of the rainy season. Living near the equator, the plants don’t experience major shifts in daylight hours, but as days get a little shorter in fall, they start to set buds. Slightly cooler temperatures also trigger flowering.

How to Get a Christmas Cactus to Bloom

Knowing how to make a Christmas cactus bloom indoors is all about mimicking the plant's natural conditions for flowering. Be patient, avoid the most common Christmas cactus problems, and employ several strategies at once for the best results:

• Get the Lighting Right
  Recreate the natural blooming conditions by giving your Christmas cactus bright, indirect light during the day. Then, about eight weeks before you want it to bloom, ensure it gets 13 or more hours of continuous darkness each night. Even a slight disruption in the darkness can prevent flowering. Cover the plant with a blanket, box or shade cloth (like this one from Amazon) at night to ensure no interruptions.
  
• Cool it Down
  Flowers are also triggered by slightly cooler temperatures. The ideal Christmas cactus temperature is between 60 and 68°F (15 to 20°C). Avoid any sudden or drastic changes in temperature, which can cause bud drop.
  
• Water Correctly
  Proper Christmas cactus watering is crucial. Although they are native to the rainforest, the plants should never be overwatered. Keep the soil moist but not soggy. Use a medium that drains very well. Leading up to bloom time, restrict water slightly – this will send stress signals it’s time to flower. Water plants only when the topmost, about 1 inch (2.5cm), layer of soil is dry to the touch. Consider buying a moisture meter, like this simple one from Amazon, to monitor the moisture level of your soil.
  
• Fertilize Well in Advance
  As with other plants, Christmas cactus fertilizer, such as this organic succulent & cactus plant food from Amazon, is best applied during its growing season (spring and summer). In the fall, switch to a fertilizer with lower or no nitrogen to encourage flower over leaf growth. Or simply cut back entirely on fertilizing.
  
• Prune in Summer
  Learning how to prune a Christmas cactus is an important part of its care. Pinching back plants in summer encourages more flowering in winter; pinching tips will push the plant to branch more, giving you more flower buds later.
  
• Stay Put
  Stress can cause damage as a Christmas cactus begins to develop flower buds. Don’t move your plant in the weeks leading up to flowering. The stress of moving it can trigger bud drop. Choose a place with bright but indirect light away from drafts.

How to Make a Christmas Cactus Bloom Again

Many people treat it like an annual houseplant, but if you know how to make your Christmas cactus bloom again, you can enjoy it year-round. To encourage a second bloom later in winter or spring, reduce watering throughout the dormant season. Only water when the soil feels dry to the touch.

Continue to provide the plant with 13 or more hours of darkness at night. Also, keep it cool. Essentially, you’re creating seasonal conditions for plant dormancy, which encourage a second blooming period.

Reblooming is easy if you find the right spot for the plant. Get it to a cool spot with nighttime darkness, mostly ignore it, and it will bloom again.

What if Your Christmas Cactus Won’t Bloom?

If you cannot mimic the plant's natural conditions, then your Christmas cactus might not bloom. However, other issues can impact flowering, such as common Christmas cactus diseases or pests.

Christmas cactus wilting or yellow leaves also indicate problems that will affect rebloom, so diagnose these issues before worrying about flowering.

When repotting a Christmas cactus, use a light soil mix and a container that drains well to avoid root rot. We recommend this Back to the Roots 100% Organic Succulent & Cacti Mix, available on Amazon.

In addition, placing your plant in a drafty spot can cause buds dropping off Christmas cactus before blooming has occurred. Bud drop is a common cause of poor flowering. The plant is sensitive to changing conditions, so take time to find just the right spot for your plant and avoid moving it.

How Many Times a Year Does a Christmas Cactus Bloom?

Christmas cactus usually booms once a year, but with the right care, you can make it bloom twice. Plants can flower for weeks at a time – as many as eight weeks – so get it right and you can enjoy fabulous blooms for several months of the year.

Should a Christmas Cactus be Deadheaded?

Deadheading can be helpful in maintaining the health of Christmas cactus plants. The removal of spent blooms, as they begin to fade, can aid growers in keeping indoor containers tidy. Trimming old flowers may also help to boost bloom and encourage new growth.

The Christmas cactus (Schlumbergera x buckleyi) is a much-loved festive plant that puts on a spectacular floral display over the holidays. Unlike desert cacti, it hails from the humid tropical forests of Brazil, meaning Christmas cactus care is quite different from that of succulents adapted to dry environments.

There are three types of holiday cactus, and though "Christmas cactus" is often used collectively, the plant does differ slightly from its cousins, the Thanksgiving cactus and Easter cactus. In particular, the spiky-leaved Thanksgiving cactus is the one most commonly sold under the Christmas label. If you’re unsure which type you own, don’t worry. Christmas and Thanksgiving cactus care is almost identical, and both rely on the same light and temperature cues to bloom. Easter cactus care is a little more involved, however, as the plants are more particular.

With proper care, the Christmas cactus can live for generations – sometimes over a century – making it a true family heirloom. Follow the advice below to keep your plant in perfect health and flowering on cue each year.

Quick Christmas Cactus Facts

Identifying a True Christmas Cactus

Many plants sold as "Christmas cacti" are actually varieties of the more common Thanksgiving cactus (Schlumbergera truncata), which blooms several weeks earlier. The true Christmas cactus (Schlumbergera x buckleyi) is a hybrid, and you can tell it apart by looking at its stems, flowers, and growth habit.

Here’s a quick guide to identifying your plant:

• Leaves: The stem segments of Christmas cactus are smooth, with rounded, scalloped edges. In contrast, Thanksgiving cacti have spiky leaves with pointed "claws" on the edges.
• Growth habit: Christmas cactus has stems that arch gracefully, while Thanksgiving cacti are typically more upright and stiff.
• Bloom time: True to its name, the Christmas cactus blooms late December through January, while the Thanksgiving cactus flowers between November and early December.
• Flowers: Christmas cactus flowers are magenta to pink in color and hang down like pendants. Thanksgiving cacti flowers are more tubular, in shades of pink, red, or white.
• Anthers: Christmas cacti have purplish anthers (the part of the stamen that holds pollen), while Thanksgiving cacti have yellow anthers.

You may also see an Easter cactus (Rhipsalidopsis gaertneri, formerly Schlumbergera gaertneri), but it's easier to tell apart due to its spring bloom time (March-May) and distinctive star-shaped flowers.

This guide focuses on the care for the true Christmas cactus, though the needs of other holiday cacti are similar.

Christmas Cactus Care Guide

Native to the coastal mountains of Brazil, the Christmas cactus grows beneath the canopy of tropical forests. It is an epiphyte plant, meaning it lives in tree branches and rock crevasses, anchoring itself using aerial roots. Rather than soil, it absorbs moisture and nutrients from surrounding humus and plant debris.

When grown indoors, Christmas cacti take in moisture and nutrients from their potting mix. The better you can mimic their native rainforest conditions – through the right temperature, light, feeding, and moisture – the healthier your plant will be.

That might sound like a lot, but these plants are surprisingly easygoing. They are well-suited to the home environment and only need to follow a few simple rules to get a good show of flowers.

Christmas Cactus Light Requirements

In their natural environment, Christmas cacti are understorey plants that receive mostly filtered sunlight. So, when grown as houseplants, the best position is near a bright window but with protection from strong afternoon sun. An east or south-east window is ideal, but the plants can be grown in south-facing rooms if a sheer curtain is used to filter the light.

Christmas cactus light requirements are most important in the 6 to 8 weeks leading up to flowering. At this time, the plants require a long, uninterrupted period of darkness each night. If you want blooms for Christmas, then in early to mid October, place it in a room where it can experience 12-14 hours of total darkness each night, or cover it with a box or breathable bag.

How Often to Water a Christmas Cactus

Christmas cactus moisture needs are quite different from those of a desert cactus. These are tropical succulents that experience more rainfall and humidity. When rainwater is scarce, they take moisture from dew and surrounding organic matter. Sites like these aren’t naturally moist all the time, nor are they extremely dry.

Watering Christmas cactus should be frequent in the spring and summer when growth is active, and reduced in the cooler seasons. Aim for every 1 to 2 weeks in spring and summer and every 2 to 3 weeks in fall and winter. But be guided by the feel of the potting mix, allowing it to dry out somewhat between watering intervals, but not completely.

Avoid being too liberal with watering, which will lead to stem and root rot, and can also attract pests like fungus gnats. If the plants are looking yellow and wilting and the soil is wet, then you need to take action. Overwatered Christmas cactus care involves removing the plant from its container, rinsing it, and trimming rotten roots, then allowing it to dry out before repotting.

Using a moisture meter will take the guesswork out of watering – this Yamron 4-in-1 Soil Moisture Meter from Amazon also tests temperature, soil pH, and light levels to ensure houseplants are happy.

Temperature & Humidity

Similar to their native environment, Christmas cacti thrive in moderate warmth and average to high humidity levels indoors. During the spring and summer, the ideal daytime Christmas cactus temperature is between 65 and 75°F (18 to 24°C), with nighttime temperatures of 60 to 65°F (15 to 18°C).

However, to force flowering, plants require a cooler period during the fall, with daytime temperatures of 60 to 70°F (15 to 21°C) and nighttime temperatures of 55 to 60°F (12 to 15°C). In particular, plants should be cool overnight at this time, as night temperatures above 70°F (21°C) will inhibit bud development.

In September or October, relocate your cactus to a cooler location in the home to help signal to the plant that it’s time to bloom. You can move it back again once it has begun flowering, but avoid exposing the plant to extreme temperature changes, cold drafts, or unvented heaters, which will cause bud drop.

Christmas cacti thrive with 50 to 60% humidity, which is higher than the average home interior. Placing a tray of pebbles filled with water beneath the container is a good way to increase humidity for houseplants. The evaporation of this water will add moisture to the ambient air without exposing the roots to excess water. Alternatively, use a small humidifier, like the Homedics Portable Humidifier from Amazon.

Bear in mind that too much stagnant humidity can cause fungus in cold rooms

Best Fertilizer for Christmas Cactus

From spring through to the end of August, feed your holiday cactus once a month. The ideal Christmas cactus fertilizer is a balanced product designed for houseplants, such as this Gardenwise 10-10-10 All Purpose Plant Food on Amazon. If using a product with an NPK of 20-20-20, you should dilute the feed to half strength to avoid overfertilizing, which will damage the fine, shallow root system.

In the fall, when the flower buds begin to form, either stop fertilizing or switch to a low-nitrogen formula that is higher in phosphorus and potassium, like this CZ Garden Organics 4-10-10 Bulb and Bloom Fertilizer. This will boost flower development and prompt your Christmas cactus to bloom by holiday time.

In addition to a balanced fertilizer, an occasional application of Epsom salts dissolved in water (one teaspoon of salts in one gallon of water) will fuel the plant's high magnesium requirements. Do this no more than once a month, and not in the same week as fertilizing.

Care After Flowering

The Christmas cactus will bloom for several weeks – as many as eight weeks, ceasing in early to mid-winter.

Deadheading spent blooms will encourage the plant to produce more flowers, then once it's finished you should remove the remaining blooms.

Continue creating seasonal conditions for plant dormancy, and you can encourage a second flush of flowers in late winter to early spring. To do this, keep the cactus in a cooler part of the house with 13-14 hours of darkness overnight, and water minimally.

Plants will resume active growth in the spring, once blossoming has finished. At this stage, you can start fertilizing and slightly increase watering frequency.

How to Prune a Christmas Cactus

While Christmas cacti don't need much pruning, an occasional tidy-up after flowering will make the plant appear fuller and encourage a more attractive shape. You should also remove any damaged or diseased areas to promote good health. Always use sharp, sterile hand pruners and make each cut at a section joint.

If you are pruning a Christmas cactus to reduce its size, then remove no more than one-third of the plant each year to avoid causing too much stress. However, if your plant has become dried up, straggly, and looks dead, hard pruning may be the only way to save it. Cut it all the way back to the soil level, and water it lightly each day. It will probably surprise you by coming back to life.

Repotting a Christmas Cactus

Christmas cacti need to be repotted every two to four years, as over time they deplete the soil of nutrients and outgrow their container. Learning how to repot Christmas cactus plants is the same process as for most other houseplants. The key things to bear in mind are that you should only go up one pot size, as the succulents thrive when pot-bound. Also, the new container must have adequate drainage holes, to prevent waterlogging.

The best time to repot Christmas cacti is after the plants have bloomed, in late winter or early spring. Unless the plant is in poor health, it should not be attempted in the fall, as it may disrupt flowering.

Best Potting Soil for Christmas Cactus

Christmas cactus soil should be a well-draining, loamy mix with good fertility. It should also have a slightly acidic soil pH – 5.5 to 6.2 is ideal.

You can use a soil mix formulated for cacti and succulents, like Miracle-Gro's Cactus, Palm and Citrus Potting Mix, available on Amazon, or make your own potting medium. A simple recipe is three parts houseplant potting soil mixed with two parts perlite or vermiculite. Once you get more experienced at making your own blend, you can experiment by incorporating peat moss or pine bark.

Repotting Step-by-Step

1. Carefully slide the cactus out of its old pot. If it's stuck, gently squeeze the sides of the pot to loosen it.
2. Gently tease the root ball with your fingers to loosen any compacted roots.
3. Add a layer of fresh, well-draining potting mix to the bottom of the new pot (which should be only slightly larger than the old one).
4. Place the plant in the new pot. Check that the top of the root ball sits about an inch (2.5 cm) below the rim.
5. Fill the empty space around the root ball with more fresh potting mix, lightly patting it down as you go.
6. Water the plant lightly, just enough to settle the new soil. Do not drench it.
7. Place the newly repotted cactus in a shady location for 2 to 3 days. This helps it recover before you move it back to its usual spot and resume your normal care routine.

Christmas Cactus Care Calendar

Christmas Cactus Propagation

It's easy to learn how to propagate Christmas cactus from root cuttings and will result in lots of new plants to gift to loved ones around the holidays.

1. Start by taking a few cuttings from the plant, using clean, sharp hand pruners. Select healthy foliage, with segments comprising at least two or three jointed sections.
2. Allow the segments to dry out for a few days until the cut ends have formed calluses.
3. Insert the callused end to about a quarter of its length deep into slightly sandy soil. You can place several in one pot.
4. Moisten the soil evenly and cover the pot with a plastic bag.
5. Place the pot in a well-lit area, avoiding direct sunlight.
6. The cutting should show signs of growth within a few weeks, at which time you can remove the bag and the plant can be transferred to another container with a looser potting soil mix of compost, loam, and sand.

Common Christmas Cactus Problems

Though plants are generally trouble-free, Christmas cactus problems can arise, requiring attention. Plants that are in poor health will rarely flower, so it's essential to diagnose and deal with issues as soon as possible.

• Buds Falling Off Christmas Cactus
  This is one of the hardest issues to diagnose, requiring a process of elimination. The problem may be caused by incorrect watering, a lack of humidity, sudden temperature changes, drafty conditions, excessive heat, incorrect light, or over-fertilizing. Consider the probability of each issue and correct any imbalances.
• Christmas Cactus Flowers Falling Off
  Look out for flowers prematurely wilting before dropping off. This issue is most often caused by underwatering, but could also be caused by a lack of humidity or sudden temperature changes. If underwatering is the culprit, do not overcorrect the issue, as it could quickly lead to root rot. Give the plant a good soak, allow the water to drain through, then resume with a new regime, checking regularly to see if the soil has dried out before watering again.
• Christmas Cactus Wilting
  A limp, wilting plant is usually caused by incorrect watering. Overwatering can be devastating to Christmas cacti, but if growers are over-cautious, the plants will slowly die from dehydration.
• Christmas Cactus Dropping Leaves 
  Too much moisture is the most common cause, especially if accompanied by yellowing leaves. However, incorrect temperatures or sudden ambient changes can also cause leaf drop.
• Christmas Cactus with Yellow Leaves
  This is a common issue with several possible causes, so use a process of elimination. Root rot or disease are the worst-case scenarios, so check for these first before considering the other options, which include too much sunlight and a lack of nutrients.

• Christmas Cactus Turning Purple
  If leaves start to turn purple or red, this usually suggests poor nutrition, so assess your fertilizing schedule. Otherwise, the plant might need repotting if it is not able to uptake nutrients in the soil. Excessive light can also cause discolored leaves, so if you suspect this to be the issue, move your cactus to a spot where it receives bright but indirect light.
• Christmas Cactus Diseases
  Most diseases affecting the plant are fungal, although bacterial diseases can also occur. Check for rot, lesions, spots, browning, and mold. Where disease is strongly suspected, apply a fungicide as a soil drench, then repot in fresh soil, trimming away diseased roots and sections. If the plant continues to decline, then it should be discarded.
• Christmas Cactus Root Rot
  This is a serious disease that's almost always caused by overwatering. Symptoms include yellowing and dropping leaves, and slimy brown or black roots. A rotting smell may also be present. If root rot is caught early, you might be able to save the plant by trimming and cleaning infected roots, dusting a natural fungicide such as cinnamon, letting the plant dry out, then repotting.
• Christmas Cactus Pests
  If your plant spent summer outdoors, then you need to inspect it for pests and treat where present. Mealybugs and scale are common invaders who can weaken plants and cause stunted growth. Treat with homemade insecticidal soap or wipe them away with a cotton ball dipped in alcohol.
• Woody Stems on Christmas Cactus
  Woody stems are natural and more likely to develop on older plants. They don't need fixing, but if the branches become too long and heavy, or the plant is overgrown, then you can trim them. Usually, you can reduce a branch by up to three-quarters in length. However, very woody stems can be cut all the way back to the wood, where they will produce new green growth.

Getting a Christmas Cactus to Rebloom

Caring for these plants typically centers on making a Christmas cactus bloom in time for the holidays, but with the right conditions, you may be able to encourage a second bloom in the spring.

The key to triggering buds is to start the dark/cool routine 6 to 8 weeks before you want flowers. Provide 12 to 14 hours of uninterrupted darkness each night and maintain temperatures of 60 to 70°F (15 to 21°C) in the daytime and 55 to 60°F (12 to 15°C) at night. An unheated room that is not used in the evening is ideal. During this period, you should slightly reduce watering and stop fertilizing.

When buds appear, you can return to normal watering. It's fine to move the plant to a brighter, slightly warmer room, but avoid extreme changes in temperature or light, which may cause buds to drop.

After flowering ends in late winter, deadhead the spent blooms and, if the plant still looks strong, you can repeat the dark/cool cycle to encourage a second flush. Results vary, and a lighter second display is normal.

Christmas Cactus Outdoor Care

Christmas cacti have little tolerance for cold, so are kept as houseplants in all but USDA zones 10 to 11 (where frost is rare), and zone 9 with special considerations. However, in cooler zones, they can enjoy being temporarily relocated outside in the summer months.

If you want your Christmas cactus to live outside year-round, it needs well-draining and slightly acidic soil. If planted in the ground, amend with compost and loose organic material to improve aeration.

Position plants on the north or east side of the home, a fence or other building. This will provide the light screening necessary to keep the plant from burning in the afternoon sun, while sheltering it from the wind.

When watering outdoors, you need to take weather conditions into account. The soil will usually dry out more quickly, but avoid watering where there is plenty of rainfall or the plant could rot.

Bring Christmas cactus houseplants back inside before nighttime temperatures fall below 50°F (10°C), and check for pests. Quarantine plants for a short period before returning to their usual spot.

I always look forward to the blooming of my Christmas cactus (Schlumbergera x buckleyi). Reliably, it starts to get tiny hot pink buds on the tips of the scalloped leaves every December. By holiday time or early January, it is coated in brightly exotic flowers. Visitors to my home often ask about the plant, so I quickly learned how to propagate Christmas cactus to make gifts for friends and loved ones.

Much like other succulents, rooting cuttings is the quickest way to propagate Christmas cactus. This is a very reliable way to make new plants and costs next to nothing – just some pots and potting mix. By following a simple Christmas cactus care routine, these new plants will soon turn into flowering beauties with lifespans of a century or more.

If you have one of the other types of types of holiday cactus then you can follow this advice for those plants, as propagating a Thanksgiving cactus or Easter cactus is broadly similar. Although Easter cactus care can be a little more challenging, so it's good to know what you're working with.

Best Time to Propagate Christmas Cactus

The optimal time to propagate a Christmas cactus from cuttings is in late spring to early summer, after all the flowers are spent and have dropped off. The plant will be back to actively growing by this time, and stems are ready to be taken. However, if you missed this window and just can't wait, then it's fine to attempt propagation later in the year.

Late spring is also the best time for repotting a Christmas cactus, as the plant will have a chance to settle into its new pot before the holidays.

How to Propagate Christmas Cactus – Step By Step

Propagating Christmas cactus through stem cuttings inserted into potting mix is the most successful method, as outlined below. However, root division is an option for large, established plants.

You may also try rooting cuttings in water, although this option is far less reliable and can cause fungal issues. Also, using the municipal water supply exposes the cutting to a variety of chemicals and minerals that may disrupt rooting. If you do want to try this option, change the water frequently and watch for roots.

The plant must be healthy before taking cuttings. Avoid stems with any disease or dead spots. The exception to this is if you are trying to save a plant suffering from common Christmas cactus problems. In this instance, isolate the cuttings from other plants until you are sure they are healthy and disease-free.

1. Take Cuttings

Christmas cactus propagation usually begins by simply taking a short, Y-shaped cutting. Choose a stem with new growth for best results. The cutting should consist of 2-5 joined segments.

It's important to remove the section at a joint. This will encourage the plant to branch at that point, so it won’t damage the plant but will promote further growth.

To remove the plant material, either use a sterile, sharp knife or twist and pull upward at a 180-degree angle.

2. Let Cuttings Callus Over

Succulent plant cuttings should always be allowed to callus prior to planting. This just means leaving the section out overnight to dry at the cut end. Failure to do this can result in rotting and no root production.

If you wish, you can sterilize the section by dipping it into diluted bleach followed by a good rinse in clean water. Let the section dry out overnight or for 24 hours. The cutting can be stored for up to 3 months in high humidity and cool temperatures of around 50°F (10°C).

3. Plant Christmas Cactus Cuttings

After the cutting has had a chance to dry, prepare a planting medium. The ideal Christmas cactus soil contains potting soil as well as materials to aid drainage, such as sand, perlite, or vermiculite. We recommend this Back to the Roots 100% Organic Succulent & Cacti Mix, available on Amazon. Moisten the potting mix and drain thoroughly.

Make a hole in the potting mix and insert the cut end 1 inch (2.5cm) deep, then gently push the soil around the cutting.

Some growers claim dipping the cut end into rooting hormone before planting will enhance rooting, but it isn't strictly necessary.

4. Care For Cuttings

Place the container in a brightly lit area, avoiding direct sunlight. Temperatures should be between 70-75°F (21-24°C). Cover the container with a clear, plastic bag to make a little greenhouse, or consider a pop up greenhouse or mini greenhouse, both available on Amazon. Remove the bag daily to let excess moisture evaporate and prevent fungal issues.

Water the cutting sparingly at first to prevent rotting. Keep the soil lightly moist but not soggy.

5. Transplant Cuttings

After about three weeks, check to see if the cutting has rooted. Use a pencil, skewer, or other slender object to excavate gently at the base of the cutting. The cutting should also start showing signs of growth at the tips of its leaves, which are usually reddish in color.

Once the roots are about 1 inch (2.5cm) long, plant the cuttings in a larger container, and begin watering with diluted houseplant food. This this organic succulent & cactus plant food from Amazon is a great option. Keep the young plants in a bright location where temperatures are warm.

The cutting may wilt some in the beginning, but this is normal and will eventually subside once the plant has taken to its new environment.

Caring for Young Christmas Cactus Plants

It will take a year or two for your plants to mature before you will see your Christmas cactus bloom. In the meantime, you need to take care of the young succulents to help them become established.

While Christmas cactus can adapt to and be grown in low light, the plant will produce more blooms with brighter light conditions. However, stay away from direct sunlight, which may burn the leaves.

Christmas cactus watering is a delicate balance as plants must never be overwatered, but also not allowed to dry out completely. Check the soil regularly and only water once the top inch (2.5cm) has dried out. Make sure there is adequate drainage provided to prevent the plant from Christmas cactus root rot. Consider buying a moisture meter, like this simple one from Amazon, to monitor the moisture level of your soil.

The plants also enjoy average to high humidity levels with ideal Christmas cactus temperatures hovering between 60 and 75°F (15-24°C) in the summer and 55 to 70°F (12-21°C) in the cooler months. Placing the pot on a tray of pebbles and water can raise humidity for houseplants where the air is dry. You can get a humidity tray along with a variety of pebbles in all different colors from Amazon.

Feed plants every other week between spring and summer. The ideal Christmas cactus fertilizer is a balanced houseplant fertilizer diluted to half-strength. This organic succulent & cactus plant food from Amazon is a great option.

At the end of summer, stop fertilizing and reduce watering to help encourage blooms. The plant will need long, dark nights in the 8 weeks or so leading up to flowering. Move the plant to a room where it will be in darkness for 13-14 hours each night.
