What to Do With Orchids in May to Set Them Up for Stunning Blooms & Strong Growth This Summer – 6 Easy Tasks You Must Do Now

Most orchids grown indoors follow a rhythm – slow through winter, then picking back up as days get longer and temperatures climb. By May, that shift is already underway for most varieties.

Roots are more active, new growth is appearing on many plants, and adjustments to watering and feeding make a bigger impact now than they did in the slower months. Good orchid care in May and early June makes a noticeable difference as spring fades into summer.

To ensure your orchids bloom well and produce tons of healthy growth this season, there are a few essential care tasks you must do now before summer officially arrives.

1. Address Faded Flower Spikes

If your orchid just finished blooming, now is the moment to deal with the spike where the flower used to be. A green orchid flower spike with nodes intact can sometimes push a secondary bloom. They will be smaller flowers than the first, there will be fewer of them, but allowing a second bloom is perfectly fine as long as your plant is healthy.

Phalaenopsis orchids are the most likely to rebloom from an existing spike. Many other types of orchids won’t put out another batch of blooms. For phalaenopsis orchids, cut just above a healthy node near the middle of the spike and let the cut callus over on its own.

If the faded flower spike is yellowing or browning, cut it at the base and let your plant redirect that energy into new growth. A full recovery cycle tends to produce stronger flowering next season than pushing a tired orchid to rebloom.

2. Repot Crowded Plants

Right after blooming is a good window for repotting orchids. Your plant isn’t in flower and the spring warmth helps it settle into fresh medium faster. Most orchids need repotting every one to two years, but watch for other signals as well.

Roots circling outside the pot are one of the clearest signs your orchid needs repotting. Broken-down, soggy growing medium is another. A plant that’s too top-heavy to stay upright is also telling you something.

Regular potting soil is the wrong medium to use – it holds too much moisture and the roots can suffocate from overwatering. Orchid bark or a dedicated orchid potting mix, like this one from Amazon, provides the drainage and airflow roots need.

Before repotting, trim away any old growth that is brown and hollow. Healthy roots should be firm and either green or white in color.

3. Adjust Your Watering Schedule

Orchids in the active growth stage drink more than plants that are dormant. May is when that shift occurs for most indoor orchids. Phalaenopsis want their potting mix to dry out somewhat between waterings, but not to go completely dry.

Water your orchids roughly every seven to ten days in summer conditions. Though the roots are the real guide, so look to those for signs it’s time to water. Silvery-white roots mean it’s time for a drink, but green roots still have some moisture so you can wait on those.

The sink method works well for watering. Set your orchid pot in a few inches of water for ten to fifteen minutes, drain thoroughly, then return it to its original location. This saturates the potting medium without leaving water sitting around the crown of the plant where root rot can set in.

Cold water can stress the roots, so use room temperature water for orchids. Heavily chlorinated tap water should sit overnight to off-gas some of the minerals and salts, though it won’t remove chloramines. Filtered water or rainwater is best for watering plants.

4. Start a Feeding Routine

The best time to fertilize orchids is as they enter the active growth season and May is the start of that window. A high phosphorus formula can encourage blooming, but a balanced orchid fertilizer, like this one from Amazon, is fine throughout the growing season. Dilute plant food at quarter to half strength and apply weekly. The phrase “weakly, weekly” makes it easy to remember.

Overfeeding is a more common problem than underfeeding in orchids. It can cause salt buildup, root burn, and browning leaf tips. So go easy with the plant food. Flush the growing medium with plain water once a month or so because accumulated salts from regular feeding can build up fast.

5. Move to Brighter Light

Indoor orchids want bright indirect light and spring’s lengthening days make it easier to get there. A plant that just scraped by during the winter in a dim corner will respond well to a spot closer to an east or south-facing window. But direct sun can scorch plants, so use a sheer curtain to take the edge off.

The difference from changing lighting conditions tends to show in the leaves within a few weeks, under ideal circumstances. May is a good time to experiment with light requirements for orchids since plants are actively growing and usually respond quickly.

Leaf color is a useful way to know when it is time to move plants into a different spot. Dark green means too little light. The plant compensates by producing chlorophyll, but tends to flower less. Lighter, yellowish green suggests too much light. A medium grassy green is what healthy growth under proper lighting conditions looks like.

6. Check the Roots & Soil

Even if you don’t need to repot, now is a useful time to check what’s happening below the surface. Clear orchid pots, like these ones from Amazon, make this easy. If you have an opaque container, probe the medium with a finger or chopstick or gently tip the plant out of the pot.

Orchid potting medium that comes out wet and compacted or that smells off isn’t providing the aeration orchid roots need. If this is the case, your growing medium is probably due for a change.

A few dead roots among lots of healthy ones isn’t a cause for a concern. Simply trim them off and put back into your existing pot. But a majority of brown, hollow roots points to a watering or medium problem that repotting can solve.

Aerial orchid roots growing outside the pot are normal, too. They’re doing what orchid roots do in nature, so leave them alone. Cutting them off will set your plant back more than leaving them as is.
