Are you looking for a carefree summer annual with non-stop blooms for a shady area? If you haven’t tried it yet, now is the perfect time to indulge in Dragon Wing begonias to fill out hanging baskets and containers. The large, green leaves; semi-trailing stems; and pendulous flowers in red, pink, or white are ideal for container culture.

The Dragon Wing begonia series (Begonia hybrida ‘Dragon Wing’) is a garden staple that performs best in partial shade, but also thrives in full sun or full shade. If planted in full sun, it appreciates some afternoon shade in the warmer zones. While it is only hardy in USDA zones 10 to 11, dragon wing begonia is easily overwintered.

I have a shady porch that cries out for begonia varieties, and I usually alternate between dragon wing begonias and the BIG Series wax begonias. They are both trouble free and do well in any light. They simply are must-haves for shady areas where you want low-maintenance, showy blooms that keep on coming.

What Is a Dragon Wing Begonia?

Dragon wing is a cross between an 'Angel Wing' begonia and either a wax begonia or a species begonia, resulting in vigorous traits and superb heat tolerance. It grows from 12 to 18 inches tall and wide (30 to 46 cm), with fleshy stems and 5-inch (13 cm) glossy, green leaves shaped like dragon wings (hence its name). There is also a bronze leaf cultivar.

This shade-loving annual prefers moderate-to-fertile, moist, but well-drained soil. dragon wing begonias can tolerate a short amount of drought as well as juglone, the chemical produced by black walnut trees that causes nearby plants to fail.

Dragon wing begonias are fairly common at garden centers these days, but if you can't find any in person they're available online as live plants from Planet Desert or you can grow them from seeds from Burpee.

Planting Dragon Wing Begonias

Feature dragon wing begonias in containers, hanging baskets, window baskets, landscape beds, or even indoors for a stunning display of colorful flowers and glossy foliage. Choose containers with several drainage holes to ensure excess water is easily drained. If your containers don’t have adequate drainage holes, you can add them with a screwdriver or a drill.

Plant dragon wing begonias in a fertile, well-draining potting mix, like Content Editor Laura's favorite Miracle-Gro mix. Avoid heavy garden soils that may promote stem or root rot. Make sure the plant is not too deep in the soil or it may get stem rot. The crown (where the stems meet the roots) should be at the soil line.

Fertilize begonias when planting with a balanced liquid fertilizer such as 20-20-20, or with a slow-release fertilizer. They will need regular feeding to keep the blooms coming all summer and fall. An organic bloom-boosting fertilizer like this one from Espoma is a great choice.

When growing dragon wing begonias in containers and hanging baskets, one plant soon fills a 10-inch (25 cm) pot. For a 12-inch (30 cm) and wider container, start with three plants.

These flowers look stunning on their own, but if you want to add another plant, choose a spiller plant such as the delicate blooming bacopa, chartreuse creeping Jenny, silver-leafed dichondra or dusty miller, or chartreuse sweet potato vine.

Dragon Wing Begonia Care

Dragon wing begonias, like all begonias, prefer moist, well-drained soil. It is important, however, not to oversaturate the plants or leave them standing in water. Water begonias when the soil is dry about an inch (2.5 cm) below the soil line.

If you're growing begonias in pots or hanging baskets, they need watering more often than those in the ground. During the heat of summer, check the pots daily for dryness. Whether in the ground or in pots, adding a layer of mulch around the plants will insulate them and help prevent moisture loss.

Feed dragon wing begonias regularly, about every two to three weeks if using a diluted liquid fertilizer and every two to three months if using a slow release granular form, but follow the instructions on the package. Formulas such as 20-20-20 work well, or for an added bloom booster, the middle number (phosphorus) can be higher, such as 15-30-15. Stop fertilizing in late summer so the plant can prepare for winter.

Since the dragon wing begonia is a sterile hybrid that doesn’t produce seeds, it focuses all its attention on flowering. Not only is that a bonus to gardeners, but these everblooming plants are self-cleaning, which means you don’t need to deadhead (cut off the faded blooms). Though little pruning is needed, you may want to trim them for shape now and then or reduce leggy stems.

Common Problems

Diseases to watch out for include botrytis blight, powdery mildew, and pythium root and stem rot. Preventing fungal diseases is key. Avoid watering the leaves and clean up fallen debris in the containers. Avoid heavy garden soil or overwatering. Ensure plenty of air flow between plant foliage.

Pests such as mealybugs, spider mites, thrips, and whiteflies can be troublesome, but a blast of water from the hose will reduce their numbers. Also, remove any heavily infested leaves. Follow that with neem oil, which you can get on Amazon, sprayed on the leaves and stems if needed.

Also note that begonias are toxic to pets and horses. They contain soluble calcium oxalates, however, most of the toxic parts are in underground roots and tubers.

Overwintering

If you enjoyed the dragon wing cultivar you chose this summer, you can overwinter begonias indoors. Cut the containerized plant back by about a third and check it for pests. A blast of water should dislodge any freeloaders. Bring it inside and place it near a bright window. Do not fertilize and water much less than you did outside.

If you don’t want to bring a container plant indoors for winter, you can take 4-inch (10 cm) cuttings to root in water or potting soil to propagate begonias to grow on next year. Wait until the threat of frost is past in the spring before moving your plants back outside. Resume watering and fertilizing and, before you know it, your dragon wing begonia will be back!

Begonias bring reliable color and texture to shady gardens, patios, and indoor shelves alike. There are begonia types that offer something for every spot – nonstop flowers, dramatic foliage, or trailing habits that fill spaces beautifully year-round, all while tolerating conditions many other plants can't.

Begonia varieties number in the thousands, but a handful of core types cover most gardening needs. These types of begonia plants range from compact outdoor bedding plants to tall indoor statement varieties and painted-leaf showstoppers that thrive with minimal attention and forgive occasional slips.

Many gardeners adore begonias for their shade tolerance and long-season performance both inside and outdoors. General begonia care applies across all the major groups, though each type requires slight tweaks for the best results. I'll walk you through the common types of begonias, the beautiful benefits and unique quirks of each one, and some basic care tips.

Common Begonia Types

There are thousands of different begonias split into a handful of different categories. Here are 7 of the most common types gardeners should know.

1. Wax Begonias (Semperflorens)

Wax begonias, which are classic summer bedding plants, stay low and bushy. They have glossy rounded leaves in either green or bronze that are topped by clusters of small flowers in white, pink, or red. Try classics like this Cocktail series mix from Amazon for beautiful bronze foliage contrast against bright flowers.

This flowering type of begonia blooms nonstop through heat and humidity, which makes them perfect for summer gardens. Stems branch naturally, forming neat mounds that are ideal for edging paths.

Wax begonias excel outdoors in partially shaded beds and containers, handling morning sun or filtered light without fading. Indoors, either east or west windows keep them compact and flowering steadily through winter.

Pinch tips early for denser growth and more blooms. Deadhead spent blooms occasionally for fresh flushes all season. Overwinter cuttings indoors in cold zones by rooting stems in water. Fibrous roots fill pots quickly and transition easily from indoors to outside in the garden for another season of blooms.

2. Cane Begonias

Cane begonias grow upright on bamboo-like stems, often splashed silver or spotted, with asymmetric angel-wing leaves and dangling pink or white flower clusters year-round indoors.

Popular spotted types like this polka dot Begonia maculata from Costa Farms bring dramatic patterns that catch light beautifully. Heights reach several feet over time, adding vertical interest to mixed plantings.

Bright, indirect light indoors prevents legginess. Lower light areas reduce blooms but foliage shines anyway. Water begonias evenly, letting the top inch (2.5 cm) or soil dry slightly between waterings to mimic native rhythms. Airy rooms suit these begonias best and higher humidity boosts leaf size and glossiness.

Prune tall canes for bushiness and shape. Use trimmings to propagate more plants. Cuttings root quickly in water or soil, multiplying favorites free. Fertilize begonias lightly spring through fall for steady new canes. Support heavy stems with stakes if leaning.

3. Rex Begonias

Rex begonias steal the show with wild foliage. They have heart-shaped leaves that are swirled, spiraled, or appear metallic. They come in purples, silvers, reds, and greens with textured veins or ruffles. Foliage varies wildly by cultivar, like this 'Escargot' begonia from Amazon, with tight spirals. Flowers stay tiny and secondary to the painted patterns that shift with light angles.

They prefer humidity and indirect light. Dry air crisps edges fast while direct sun scorches patterns pale. Keep soil lightly moist, mist leaves regularly for vibrant colors and perkiness. Rotate pots for even light exposure on all sides. Terracotta pots breathe well for roots.

Avoid cold drafts below 60°F (16°C) that drop leaves. Leaf drop signals stress. Adjust water or light promptly. Propagate leaf wedges in moist mix under covers for new plants.

4. Rhizomatous Begonias

Rhizomatous begonias spread via thick surface roots, pushing textured or patterned asymmetric leaves above the soil in low mounds that creep slowly outward. Many feature hairy, puckered, or blistered surfaces adding dimension and touch appeal. Try textured favorites, like this unique Begonia masoniana from Amazon, with bold markings.

Medium light indoors suits these begonias well. Direct sun scorches delicate foliage quickly while low light spots stretch stems. Water when top dries, avoiding soggy conditions that rot rhizomes fast. Elevated humidity perks leaves and prevents browning.

Fertilize sparingly – too much pushes weak, leggy growth over compact form. Compact habits fit shelves or terrariums perfectly. Divide clumps every few years for rejuvenation and extra plants. These begonias overwinter easily as houseplants without dormancy.

5. Tuberous Begonias

Tuberous begonias produce huge ruffled blooms like roses or camellias in bold oranges, yellows, pinks on either upright or trailing stems. They grow from underground tubers that swell with stored energy. Flowers layer deeply, hanging heavy and facing outward.

Filtered shade outdoors prevents sunburn. Morning sun will work in temperate climates without crisping petals. Consistent moisture rewards long-lasting summer shows. But dry spells drop buds fast and overwatering rots tubers.

Lift tubers to winterize begonias in cold climates. Start seeds early indoors for a head start in the garden. Trailing types cascade beautifully from baskets. Grab reliable performers like tuberous begonias from Nonstop series on Amazon.

Pinch early shoots for branching and more flowers. Cool nights extend bloom time noticeably. Tubers multiply over seasons and you can divide them for larger displays.

6. Trailing-Scandent Begonias

Trailing-scandent begonias cascade long flexible stems loaded with flowers or fancy leaves, filling baskets with color or texture from spring through fall. They can grow and reach several feet down out of containers. Trailing types, like Begonia x boliviensis that you can get as seeds on Amazon, are perfect to hanging baskets.

Part shade outdoors or bright indoors works best for these begonias. Pinch plants regularly for fuller branching and heavier cascades of blooms. Water consistently, but drain well to avoid stem rot at the soil line. Cuttings multiply fast in water or potting mix.

Humidity encourages lush growth and bigger leaves. This begonia is frost tender, so bring it inside before cold snaps hit. It’s versatile for height variation in mixed hangers. Combine bloom-heavy and leaf-focused cultivars for layered interest.

7. Rieger Begonias (Hiemalis)

Rieger begonias bloom heavily indoors with rose-like flowers in warm shades over glossy green leaves. These indoor begonia plants are bred specifically for winter performance under lower natural light and cooler rooms.

Bright, indirect light is preferred. Cool nights encourage buds while steady warmth pushes foliage. Keep soil moist evenly, fertilize lightly during bloom cycles for repeats. Compact size fits tables or counters perfectly. Extend seasons with prompt deadheading.

Lower light tolerance makes them winter stars indoors. Propagate stem tips carefully in spring. Flowers drop clean without mess. You can find live Rieger begonia plants for sale on Etsy.

Indoor begonia plants continue to gain popularity among enthusiasts and collectors. Begonias are lovely in the landscape, adding lasting color to borders and shaded beds, with some species being better suited to garden growth than others. Why not try growing indoor begonias? Especially exciting cultivars offer a wide array of sizes, colors, patterns, and textures from which to choose.

Below, we’ll discuss growing some of the best begonia varieties indoors, and their care.

Choosing Indoor Begonia Plants to Grow

Shop carefully for your begonias, choosing those known to thrive indoors. More common species, like wax or tuberous varieties, are often better left to grow outdoors. Fibrous or rhizomatous types are a much better option for containers, or when kept as a houseplant. This is due largely to their needs in relation to light, water, temperature, and their growth cycle. Indoor begonia types such as these are generally considered highly ornamental, adding impressive year-round beauty to your indoor growing space.

1. Arctic Breeze

Rhizomatous types are among the most popular indoor begonia varieties. Arctic Breeze (Begonia rex) is no exception. Its intense purple foliage takes on a unique, frosted appearance, giving leaves an interesting metallic look. These compact plants are well-suited to growth where space is limited. This includes plant stands, countertops, or even hanging baskets. Begonias of this type will require both warmth and humidity to flourish.

2. Emerald Giant

Like many begonias grown as houseplants, Emerald Giant is beloved for its attractive foliage. Large leaves please gardeners with their distinctive swirled pattern, ranging in both shade and color. Indoor plants are best positioned near an east or west-facing window, where they are able to receive bright, indirect light throughout the day. Routine feeding, in tandem with the use of a high-quality acidic potting mix, will further aid in their growth.

3. Double Silver Dot

Double Silver Dot remains among the most sought-after types of indoor begonias. True to their name, first-time growers can expect stunning green foliage, dotted with silver spots. Vividly patterned leaves draw the focus of both growers and guests with ease. Gloss and shine further enhance these short-statured plants' ability to create a lush, tropical feel, complementary to indoor spaces and easily incorporated into home design.

4. Merrymaker

Merrymaker begonias are best known for their vibrant color. Those growing the plant can expect bright, magenta-pink foliage. Deep burgundy veins run through each leaf and toothy edges add both texture and interest to containers. These are a good choice if you’re looking for especially appealing focal plants. Where conditions are ideal, indoor specimens may bud, producing spritely pink blooms.

5. Neon Splash

Those growing Neon Splash delight in the plants' unique ruffled appearance. Rhizomatous plants produce an abundance of foliage, splashed with brilliant lime-green markings. Well-suited to small containers, these diminutive plants are an ideal addition to shelves, window sills, and other decorative nooks. Clusters of attractive pink blooms are likely to persist through winter, provided plants receive ample light and consistent warmth.

6. Polka Dot

One of many Begonia maculata types, Polka Dot is sure to dazzle gardeners with its narrow, spotted foliage. As the species is regarded for their ease of care, this variety remains especially popular among novice growers, and is often gifted to would-be plant parents.

Plants will flourish where the indoor climate remains relatively cool, between 65-75 F (18-24 C). Potted specimens should be positioned safely away from vents, and protected from drafts or sudden fluctuations in temperature.

7. Purple Blush

Similar in form and foliage to other Begonia rex types, Purple Blush remains among the best indoor begonias in terms of color and dramatic visual appeal. Large leaves are patterned in attractive shades of green, pink, purple, blush, and silver. The production of modest flowers only adds to their beauty, opening sporadically throughout the year. As with other species, the cultivar will appreciate consistent moisture and humidity as a means to perform its best.

8. Red Tempest

Known best for their dramatic foliage, Red Tempest begonias make a statement. White-silver leaves unfurl to reveal a veritable landscape of purple-pink tones. Serrated leaves, edged in black, add further beauty to containers with their immense contrast. Continued feeding and warmth throughout the year will aid in this plant’s growth and the overall color development in foliage.

Getting to grips with begonia watering is a vital aspect of plant health. This is just as true whether you are growing begonias as houseplants or as an ornamental in beds and borders. However, correct hydration includes gaining a better understanding of how much water each plant will need per week in your own specific growing zone. 

Learning to properly water a begonia from below is essential in preventing disease and supporting function. Using drip irrigation lines or soaker hoses are amongst the best options for watering begonias, as well as submerging the pots or hand-watering. This article will delve further into the most common questions about how often to water begonias and the best methods of watering them. 

Watering Begonias in Open Ground

Begonias grow best in garden beds that have exceptional drainage; oversaturation or prolonged standing water can lead to the development of begonia plant diseases such as leaf spot or other fungal infections. Your plant’s need for water will vary depending on the region and climate. 

While begonias grown in areas with ample rainfall only seldom require supplemental irrigation, those in drier climates may benefit from weekly watering. As a rule of thumb, water your begonias when the soil’s surface has dried to the touch, or once every four days.

Watering Begonias in Containers

Begonias grown in containers require water with much greater frequency. Weekly irrigation is likely to be needed throughout the plant’s period of active growth in spring and summer. Generally, the rate of watering should increase as temperatures rise throughout the season. The need for water also varies depending on humidity and the containers you’ve selected. 

Begonia watering for pot-based plants relies on a degree of daily inspection. Gardeners should carefully monitor potted begonia plants for signs of stress or other indicators that water is needed, making certain to meet their needs before plants begin to droop or wilt.

Watering Begonias in Winter

When it comes to overwintering begonias, a plant’s need for water is reduced greatly. During the colder months, there is far less risk of an underwatered begonia falling foul of neglect. Hardy types grown in garden beds are unlikely to require supplemental water. However, irrigation may be necessary if conditions are especially warm or dry. 

It’s essential to avoid overwatering during periods of cold, however, when conditions are most suited to rot. Potted begonia plants that have been moved indoors benefit from routine weekly watering. Pay special attention to humidity levels throughout winter. Help your plants with frequent misting or by placing containers atop a shallow bed of gravel filled with water.

Liquid Fertilizers for Begonias

Alongside knowing how to water begonias, it’s also important to apply liquid feeds at the correct time, and in the best way. Using liquid fertilizer is a quick and easy way to feed begonia plants in a controlled way. Balanced feeds, specifically formulated for use with ornamentals, should first be applied in early spring. 

Continue to fertilize the plants throughout the season, as needed, working in tandem with your begonia watering schedule. Decrease feeding your begonia when the plant stops blooming, allowing the plant ample time for preparation for winter.

Frequently Asked Questions

Begonia plants make a lovely addition to ornamental flower beds, containers, and even hanging baskets. Thriving under a wide range of growing conditions, it is likely that gardeners are able to find either annual or perennial varieties which best suit their specific needs. Though some types produce large, showy flowers, many other cultivars are known for their dramatic dark foliage. Below we will explore some of the most popular varieties of dark leaved begonias available to home gardeners. 

Popular Varieties of Begonia with Dark Leaves

1. ‘Dancing Peacock’ - This variety of begonia offers growers a stunning array of pink, purple, and black foliage. When planted in full shade, ‘Dancing Peacock’ produces ornamental leaves in highly-saturated, colored patterns. In addition to its spectacular foliage, this begonia may also produce small pink blooms when grown where conditions are ideal. 
2. ‘Jurassic Silver Swirl’ - ‘Jurassic Silver Swirl’ is a tropical tuberous begonia that behaves as a perennial in frost free regions. The leaves of this unique black begonia feature a distinctive silver swirled pattern. Like other tuberous begonias, this variety can be grown as an annual. However, it should be noted that it may not thrive in regions with excess heat and/or humidity.
3. ‘Megawatt Red Bronze’ - This variety of bronze leaf wax begonia is commonly grown as an annual and is often used as a bedding plant. Short-statured plants grow well in a wide range of light conditions, including both part shade and part sun. Deeply colored bronze foliage serves as a brilliant contrast to bright pink-red flowers, which are held high above the plant.
4. ‘Sophia’ - ‘Sophia’ bronze-leaved begonias are considered an “angel wing” type. These begonias are known for their fantastic foliage, upright growth, and ability to reach impressive heights. ‘Sophia’ begonia produces masses of leaves in shades of deep, dark purple-mahogany and black.
5. ‘Sparks Will Fly’ - An excellent candidate for growth in containers and hanging baskets, this variety will produce the most vibrant, ornamental color when grown in part to full shade. Leaves of the plant are dark purple, almost black. Frequently, foliage is also patterned with green veining, which adds even more dimension. These dramatic colors contrast nicely with an abundance of bright orange blooms that are produced throughout the duration of the entire growing season.

There are more than 1,000 species of begonias worldwide, each with a varying bloom color or foliage type. Since there is such a great variety, begonias are a popular plant to grow. But, how do you know when to repot a begonia?

Moving a begonia to a bigger pot isn’t always an easy decision, since begonias like to be somewhat root bound. Repotting begonias at some point is necessary to boost soil nutrients and aerate the soil, making begonia transplants healthier.

When to Repot a Begonia

Since begonias like to be root bound, wait to repot until the container is filled with roots. This will be clearly obvious if you gently remove the plant from its pot. If there is still loose soil, allow the begonia to continue growing. When the plant’s roots hold all of the soil, it’s time for a transplant.

A begonia transplant may not always need a larger container. Sometimes a begonia may wither and fall over. This means the roots have begun to decay, and there is too much soil providing a surplus of nutrients (and water), more than the plant needs. In this case, you won’t be moving the begonia to a bigger pot, but rather a smaller one.

Now that you know when to repot begonias, it’s time to learn how to repot a begonia.

How to Repot a Begonia

When moving begonia to a bigger pot, select a slightly larger pot for the transplant. Slightly means to choose a pot that is an inch (2.5 cm.) larger than its previous pot. It is better to gradually increase the size of the pot as the plant grows, rather than plunking it into a huge container, which can lead to root rot.

Before repotting at all, make sure the plant has a solid root structure. Choose a pot with adequate drainage holes.

Use a soilless planting medium that is equal parts peat moss, vermiculite, and perlite. Amend the medium with a couple of tablespoons of ground limestone to help control humidity. Mix together well and moisten with water.

Gently remove the begonia from its container and immediately transplant it into the new medium. Water the begonia transplant and acclimate it in an area out of direct sun.

Begonias are herbaceous succulent plants that hail from the tropics. They are grown for their gorgeous blossoms and spectacular leaf shapes and colors. One of the more common types of begonias grown is the rhizomatous, or Rex begonia. Interested in growing begonia rhizomes? Read on to learn how to grow rhizomatous begonias and about rhizomatous begonia care.

What is a Rhizomatous Begonia?

There are around 1,000 species of begonia with about 10,000 cultivated cultivars and mutations. Amongst the major classifications are the fibrous rooted, rhizomatous, and tuberous rooted begonias.

Rex begonias are herbaceous perennials in USDA zones 10 through 12, so they are more commonly grown as houseplants or annuals. While they do flower, they are grown more for their vibrant, textured leaves. In fact, they are also referred to as ‘fancy-leaf,’ ‘painted leaf,’ or ‘king’ begonias.

Rhizomatous begonias range in size from quite small to immense with 3 foot (1 m.) leaves, although their size is in breadth, not height. They grow from rhizomes underground, hence the name. Interestingly, Rex begonias are tolerant of juglone toxicity produced by black walnut trees.

Is Rhizomatous Begonia Different from Tuberous Begonia?

This is a commonly asked question and, yes, rhizomatous begonia is different from tuberous begonia. Tuberous begonias are the most spectacular bloomers of the begonias. They are grown from tubers rather than rhizomes. They are often grown in the garden, but their sensitive nature means they must be dug up and preserved in peat moss over the winter months.

How to Grow Rhizomatous Begonias

When growing begonia rhizomes, some attention to detail is necessary, as these plants can be particular in their needs. They prefer bright but indirect sunlight. Outdoors, situate Rex begonias in containers, hanging baskets, or beds in full to partial shade. Inside, Rex begonias thrive in easterly facing windows or set back from southern or western exposures.

They also prefer relatively high humidity and flourish in bathrooms or kitchens where humidity levels are often higher. Plants can also be placed on trays of wet pebbles or marbles.

Rhizomatous Begonia Care

Besides their penchant for low light and high humidity, begonias in general should be fertilized during the growing season. Fertilize with a water-soluble food that has been diluted to quarter strength once every two to three weeks during the growing season. Refrain from fertilizing from fall until new growth emerges in the spring.

Rex begonias like to be consistently moist but not saturated. Wait to water until the top inch (2.5 cm.) of soil feels dry to the touch. Water at the base of the plant and avoid wetting the leaves, which can leave the plant open to powdery mildew. Also, when the plant goes dormant from fall to spring, reduce the amount of water given to the begonia.

Begonias are a long-time favorite of many flower gardeners. Whether growing in the ground or in containers, the options are truly limitless. Begonias offer vibrant pops of color through their distinct foliage and beautiful blooms. With all this beauty, it is easy to understand why many growers may become alarmed when they begin to notice changes in the appearance of their begonia plants. Curling begonia leaves are one example that can lead gardeners on a search for answers.

Reasons for Begonia Leaf Curl

As with any garden question, the reason behind why begonia leaves are curling may be difficult to diagnose. A begonia with curled leaves may have been affected in a number of ways in order for this to occur.

First, growers will need to carefully observe recent changes in water, fertilization, or even weather patterns. Each of these issues can cause begonia leaf curl.

• Temperature – Since many begonia plants are native to tropical regions, curling begonia leaves may occur when plants have been exposed to wide temperature change. Ideally, the plants will grow best when temperatures do not fall below 60 F. (15 C.). Sudden periods of cool weather can certainly cause the appearance of the begonia plant to change.
• Water/Fertilization – Begonia curl may also occur due to overwatering, underwatering, or overuse of plant fertilizer. Maintaining a consistent schedule of each of these garden tasks will help growers to better diagnose the cause of leaf curl.

If after close monitoring, none of these factors is the issue, there are some pest and disease-related causes to consider. Thrips, for example, are among the most common begonia pests which may cause leaves to curl.

Many types of begonia plants are also susceptible to powdery mildew. Begonia leaf curl is often among the first symptoms. Beyond curling, gardeners will then begin to notice distinctive white patches on the leaves of the plant. Eventually, the disease may cause flowers and leaves to die back and fall from the plant.

Other types of plant diseases, such as anthracnose, can be caused by fungi. Anthracnose in begonia plants is common. Curling of begonia leaves is often among the first noticeable symptoms of this issue as well. Inspect the leaves of the plant for signs of yellowing or brown spotted lesions. To help prevent this disease in begonias, remove any signs of infected plant material and make certain to avoid wetting the leaves while watering.

Many people might be shocked to know that certain begonias are grown for their leaves rather than their flowers. The rex begonia plant is one of those! Although they do flower, the main attraction is the beautiful and ornate foliage that it produces. Rex begonia care indoors can be a little tricky, but it is certainly possible to grow beautiful specimens if you understand the plant’s needs.

Let’s take a look at the most critical elements of growing the rex begonia as houseplants.

Growing Rex Begonias Indoors

Rex begonias are rhizomatous begonias. A rhizome is basically a thickened stem, and the leaves emerge from the rhizome.

Generally, the rex begonia indoors prefers relatively cool temperatures, moist soil, and humid conditions. 

Rex begonias do well in bright indirect light. Some direct sun is okay for short times, especially if it is from an eastern window that has morning sun, which is gentler. For periods of the year where the sun is strongest, or if you live in an area that has strong sun, you will want to avoid too much direct sun. You can easily use sheer curtains to diffuse direct sun, or set the plant a few feet back from a very sunny window. Too much direct sun can burn the foliage. 

Rex begonias prefer to grow in a fairly evenly moist soil. However, you must have a good balance because these plants can easily be prone to root rot. A good rule of thumb is to allow the top inch or so (2.5 cm.) to dry out, then water again. It is better to keep the soil on the slightly drier side, but never let the soil completely dry out, as this can quickly spell death for your rex begonia. If you let the soil get too dry, your plant will quickly wilt.

As far as fertilizing goes, you can fertilize with a dilute solution about twice a month during the active growing season. Avoid fertilizing during the winter months when plant growth can come to a halt. 

Also, avoid allowing your rex begonia’s leaves to be wet for extended periods of time, especially at night, since this can encourage powdery mildew as well as bacteria leaf spot. 

As far as soil goes, rex begonias like a light and airy soil. Avoid any heavy potting mixes. Potting mixes designed for African violets are a good choice for rex begonias. 

Rex begonias like conditions with high humidity. In fact, the foliage will grow larger when the humidity is higher. Aim to increase the humidity, especially during the winter months, by a few different methods. You can place a plant on a tray with wet pebbles, use a humidifier, or place them in naturally humid areas such as a bathroom. You can also group plants together to increase humidity through plants’ natural process of transpiration. 

Finally, choose a pot that is wider than it is deep since this is more appropriate for rhizomatous plants like rex begonias. If you’d like to propagate them, you can do so by leaf cuttings or by cutting sections of the rhizome and repotting. 

Begonias are among America’s favorite shade plants, with lush leaves and splashy blossoms in a multitude of colors. Generally, they are healthy, low-care plants, but they are susceptible to a few fungal diseases like botrytis of begonia. Begonias with botrytis is a serious disease that can endanger the life of the plant. Keep reading for information about treating begonia botrytis, as well as tips about how to avoid it.

About Begonias with Botrytis

Botrytis of begonia is also known as botrytis blight. It is caused by the fungus Botrytis cinerea and is most likely to appear when temperatures dip and moisture levels rise.

Begonias with botrytis blight decline rapidly. Tan spots and sometimes water-soaked lesions appear on the foliage and stems of the plant. Cuttings rot at the stem. Established begonia plants rot as well, starting in the crown. Look for dusty gray fungal growth on infected tissue.

The Botrytis cinerea fungus lives in plant debris and multiples quickly, especially in cool, high moisture conditions. It feeds on wilting flowers and senescent leaves, and from there, attacks healthy leaves.

But begonias with botrytis blight are not the only victims of the fungus. It can also infect other ornamental plants including:

• Anemone
• Chrysanthemum
• Dahlia
• Fuchsia
• Geranium
• Hydrangea
• Marigold

Begonia Botrytis Treatment

Treating begonia botrytis begins with taking steps to prevent it from attacking your plants. While it won’t help your begonias with botrytis, it will prevent the disease from passing to other begonia plants.

Cultural control starts with removing and destroying all dead, dying or wilting plant parts, including dying flowers and foliage. These dying plant parts attract the fungus, and removing them from the begonia and potting soil surface is a very important step.

In addition, it helps keep the fungus away if you increase air flow around the begonias. Don’t get water on the leaves as you are watering and make an attempt to keep the leaves dry.

Fortunately for begonias with botrytis, there are chemical controls that can be used to help infected plants. Use a fungicide that is appropriate for begonias every week or so. Alternate fungicides to prevent fungi from building up resistance.

You can also use biological control as begonia botrytis treatment. Botrytis of begonia was reduced when Trichoderma harzianum 382 was added into a sphagnum peat potting media.

Begonias are among the most popular of all annual flowers. They come in a variety of types and colors, they tolerate shade, they produce both pretty blooms and attractive foliage, and they won’t be eaten by deer. Caring for begonias is pretty easy if you give them the right conditions, but watch out for signs of powdery mildew and know how to prevent and manage this disease.

Identifying Powdery Mildew on Begonias

Powdery mildew is a fungal infection. Begonias with powdery mildew are infected by Odium begoniae. This species of fungus only infects begonias, but it will spread readily between begonia plants.

A begonia with powdery mildew will have white, powdery or thread-like growths on the top surface of leaves. The fungus may additionally cover stems or flowers. The fungus feeds from the leaf cells, and needs the plant to survive. For this reason, the infection does not kill plants, but it may cause poor growth if it becomes severe.

Begonia Powdery Mildew Control

Unlike other fungal infections, powdery mildew does not require moisture or high humidity to grow and spread. It spreads when wind or other action physically moves the threads or powder from one plant to the next.

Giving plants adequate space and quickly destroying any diseased leaves can help control infections. If you see powdery mildew on begonia leaves, wet them to prevent spread and then remove and dispose of them.

How to Treat Begonia Powdery Mildew

Powdery mildew fungus thrives optimally at around 70 degrees Fahrenheit (21 Celsius). Hot temperatures will kill the fungus. Changes in humidity can trigger the release of spores. So, if you can move affected begonias to a location where they will be warm and the humidity is stable, like a greenhouse, you may be able to kill the fungus and save the plants.

Treating begonia powdery mildew can also be done with chemical and biological agents. There are several fungicides that will kill the powdery mildew that infects begonias. Check with your local nursery or extension office to find a good option for a fungicide or a biological control.

Begonia plants are a popular choice for garden borders and hanging baskets. Readily available at garden centers and plant nurseries, begonias are often among the first flowers added to newly revitalized flower beds. Highly praised for their varying colors and textures, both tuberous and seed grown begonias offer growers a plethora of colorful flowers and waxy multi-colored foliage.

With these attributes in mind, it is easy to see why many growers may have cause for alarm when their previously healthy begonia plants begin to show signs of distress, such as leaf spots on begonia.

What Causes Begonia Leaf Spot?

Leaf spots of begonia are caused by a pathogen called Xanthomonas. Among the first signs and symptoms that growers may notice when dealing with leaf spot on begonia is the appearance of darkened spots or “water soaked” leaves. As the disease progresses, leaf spot can continue to spread throughout the host plant and to other begonia plants near it. If severe, the begonia plant will eventually die.

Leaf spot on begonias is a disease which is most commonly spread by infected plant matter. Begonias with leaf spot are often introduced into the existing flower bed, thus causing problems in the garden.

Treating Begonia Bacterial Leaf Spot

The best way to maintain a healthy planting of begonias is to monitor and check the overall health of the flowers before planting them into the garden. Closely examine the leaves of the begonia plants. The first signs of begonia leaf spot may often be present on the underside of the plants’ foliage.

Buying from a reputable source will help to decrease the likelihood that the begonia plants have come into contact with this bacterial issue.

In some cases, presence of the bacteria may not be immediately apparent. If begonia leaf spot does become an issue in the flower bed, growers can help combat it by removing and destroying infected plants.

Always make certain to thoroughly clean any garden tools which have been used to handle the begonias with leaf spot, as these can spread the disease too. As with many plants, it is best to avoid overhead watering, as this process can also encourage the transport of the disease to other begonia plantings.

Begonias are gorgeous, colorful, blooming plants that can be grown in USDA zones 7 through 10. With their glorious blossoms and decorative foliage, begonias are fun to grow, yet not without their issues. One problem the grower may encounter is aster yellows on begonias. The following article contains information on how to identify a begonia with aster yellows disease and aster yellows control.

What is Begonia Aster Yellows Disease?

Aster yellows disease on begonias is caused by a phytoplasma (formerly referred to as a mycoplasma) that is spread by leafhoppers. This bacterium-like organism causes virus-like symptoms in a huge host range of more than 300 plant species in 48 plant families.

Symptoms of a Begonia with Aster Yellows

The symptoms of aster yellows vary depending upon the host species combined with the temperature, age, and size of the infected plant. In the case of aster yellows on begonias, the first symptoms appear as chlorosis (yellowing) along the veins of young leaves. The chlorosis worsens as the disease progresses, resulting in defoliation.

Infected plants do not die or wilt but, instead, maintain a rather spindly, less than robust growth habit. Aster yellows may attack part or all of the plant.

Begonia Aster Yellows Control

Aster yellows overwinters on infected host crops and weeds as well as in adult leafhoppers. Leafhoppers acquire the disease by feeding on the phloem cells of infected plants. As early as eleven days later, the infected leafhopper can transmit the bacterium to plants it is feeding on.

Throughout the lifecycle of the infected leafhopper (100 days or longer), the bacterium multiplies. This means that as long as the infected leafhopper lives, it will continuously be able to infect healthy plants.

The bacterium in the leafhoppers can be quelled when temperatures surpass 88 degrees F. (31 C.) for 10 to 12 days. This means that hot spells lasting for more than two weeks reduce the chances of infection.

Since weather cannot be controlled, another plan of attack must be followed. First, destroy all susceptible overwintering hosts and destroy any infected plants. Also, remove any weed hosts or spray them prior to infection with an insecticide.

Place strips of aluminum foil between the begonias. This is said to aid in control by disorienting the leafhoppers with the reflection of the light playing against the foil.

As a gardener, it can be overwhelming when trying to assess your garden’s fertilizer needs. So many questions: Does this plant need fertilizer? What kind of fertilizer? How much fertilizer? When and how to fertilize? You get the picture. The struggle is real; so real that many gardeners don’t bother to fertilize anything, even their tuberous begonias!

Feeding Tuberous Begonias

I need a moment to process that last part – tuberous begonias. Showy and stunning with so many options. Single or double blossoms. Plain or ruffled flowers. Color palette from white to crimson with bicolor options. Cascading or upright varieties. I LOVE THEM! These are flowers that you definitely want to thrive! Fertilizing tuberous begonia is important because they are heavy feeders, not unlike most plants which are heavy bloomers. And, it is also not surprising that tuberous begonia are heavy feeders when you consider that they are also providing nourishment to their tubers - nutrition is being packed away for future growth! Read on to learn more about how to feed tuberous begonias.

How to Feed Tuberous Begonias

When it comes to tuberous begonia feeding, gentle applications of fertilizer are the recommended route. If you apply fertilizer that is too highly concentrated or if you overfeed, you will see evidence of fertilizer burn (brown crispy spots) on the begonia leaves. On the flip-side, if you are not fertilizing or under-fertilizing your begonias, you may be presented with results that are somewhat underwhelming, such as smaller-than-expected blooms or singles instead of doubles for blooms. If starting tubers indoors, it will eventually be time to transplant the plants into the containers or flower beds and think about fertilizer for a tuberous begonia. And keep in mind, these are not the only approaches you can take for tuberous begonia fertilizing.

Tuberous Begonias in Containers

For containers, I’m going to propose the easiest method for tuberous begonia fertilizing: When transplanting, fill the container half full of soil then gently set the begonia plant into the pot. For each potted plant, add in a half teaspoon of a time release fertilizer, then continue filling the pot with soil, followed by a thorough watering. You may also top-dress the soil with the half teaspoon of granules if you forget to incorporate the fertilizer into the soil as prescribed here, or if you buy a pre-planted pot of begonias. This application of fertilizer for a tuberous begonia should last for the growing season of the begonia plants.

Tuberous Begonias in Garden Beds

Prior to the onset of flower buds, you will want to administer a 5-1-1 fertilizer, such as fish emulsion for tuberous begonia feeding. Mix one tablespoon (14.7 ml.) of fish emulsion with one gallon (3.78 L.) of water and apply twice a month per plant. Upon the formation of flower buds, you will want to apply a fertilizer cocktail of the 5-1-1 fertilizer and a bloom (0-10-10) fertilizer. Mix one tablespoon (14.7 ml.) of each into one gallon (3.78 L.) of water and apply every two weeks per plant. Stop fertilizing tuberous begonia when the plant begins to decline – i.e. yellowing leaves, spent blooms, etc. This will probably happen sometime around late summer or early fall.

There are over 1,500 species and over 10,000 hybrids of begonia in existence today. Talk about beaucoup (bow coo) begonia! New cultivars are added every year and 2009 was no exception. That year, Gryphon, a new variety of begonia hybridized by PanAmericanSeed, was introduced. So, what is a Gryphon begonia? Let’s learn more about how to grow a Gryphon begonia plants.

Gryphon Begonia Information

In mythology, a gryphon is a creature with the head and wings of an eagle and the body of a lion. Don’t worry, Gryphon begonias don’t literally look like that – that would just be weird. So why is this begonia being named after a gryphon? It is because this begonia embodies the same underlying qualities that the mythical creature possesses, namely its majestic beauty, strength, and durability. Is your interest piqued? Alternately known as Pegasus™ in some sectors, the Gryphon begonia (USDA hardiness zone 11-12) strikes a dramatic pose and adds a tropical flair to any shade garden or container planting. Gryphon begonia is prized mainly as a foliage plant because it seldom blooms-- the appearance of bright pink flowers may only happen when grown under a day length of eleven hours or less. This plant is universally described as having 10 inch (25 cm.) wide, thick, glossy, deeply cut star or maple-shaped leaves. Its mounds of leaves are variegated silver and green with a hint of maroon in the veins and a maroon underside. It reaches a height of 14 to 16 inches (36-41 cm.) and spans 16 to 18 inches (41-46 cm.) across. As if this plant’s aesthetics weren’t enough to sell it, Gryphon begonia also boasts versatility as a “garden-to-house” plant, meaning it can easily transition from being an outdoor plant into an indoor houseplant and vice-versa. Care must be taken, however, to bring containers of this tender perennial inside before it is subjected to frost.

How to Grow a Gryphon Begonia

Let’s talk about Gryphon begonia care. Gryphon begonias have a reputation as an easy-to-care-for, low maintenance plant and can be grown from starter plants or seed. For a garden planting, after the threat of frost has passed, it is advised to plant your nursery plants 18 inches (46 cm.) apart in a location that receives shade to part shade. The soil in this location should be characteristically rich and well-draining. Gryphon begonias have low water requirements and do not like to be overwatered so once they are established, an occasional watering to keep the soil slightly moist should be sufficient. When growing Gryphon begonias, you may want to consider placing mulch around the root zone to retain moisture. Fertilizing is not necessary for Gryphon begonia care but, for an extra boost, an organic fertilizer can be applied every two weeks. Gryphon begonias are said to thrive better and are even livelier in container plantings. It is often used as a thriller in the center of "spiller-thriller-filler" containers surrounded by smaller plants. However, it can thrill just as effectively in a solo planting. It is recommended, when growing Gryphon begonias, to plant them in a soilless mix comprised of peat moss and perlite or vermiculite. Place the container, which should have adequate drainage, in a location that receives bright filtered light. Do not expose the container to direct sunlight. Water the Gryphon begonia only when the surface of the potting mix feels dry to the touch.

Native to the Caribbean Islands and other tropical locations, begonias are hardy in areas with frost free winters. In cooler climates, they are grown as annual plants. The dramatic foliage of certain begonias is especially popular for shade-loving hanging baskets. Many plant lovers have realized that instead of purchasing expensive begonia baskets each spring, they can overwinter them in greenhouses or as houseplants. Of course, overwintering begonia plants may require pruning. Continue reading to learn how to prune begonias.

Do I Need to Prune a Begonia?

Pruning a begonia plant depends on different factors. For instance, how and when to prune a begonia plant depends on your location, as well as which type of begonia you have. In warm, frost-free climates, begonias can grow outdoors as perennials and certain types may even bloom all year. In cool climates with frost and snow in winter, begonias need to be discarded or brought indoors to a sheltered location when temperatures begin to dip below 50 degrees F. (10 C.). However, at this point, tuberous begonias will naturally begin to die back to the ground. In cool climates, they can be dug up. The begonia foliage should be trimmed back, and the tubers can be dried and stored in a cool, dry location through winter, just as canna or dahlia bulbs are stored. Fibrous rooted and rhizomatous begonias do not die back once a year like tuberous begonias. This means that in warm tropical climates they can grow outdoors, and some even bloom year-round. In cool climates, they can be brought indoors and treated like houseplants through winter. Rhizomatous begonias are usually easy to identify by their fleshy, horizontal stems or rhizomes which run along or just under the soil surface. Many rhizomatous begonias are specifically grown as houseplants for their dramatic foliage and tolerance of indirect sunlight.

How to Prune Begonias

Whether grown outdoors year-round in warm climates or as annuals in cold climates, tuberous begonias die back annually to store up energy in their tubers while they go through a dormant phase. Rhizomatous and fibrous rooted begonias don’t die back but they are usually pruned annually to keep them full and blooming properly. In warm climates, begonia plant pruning is usually done in spring. In cool climates, begonias are pruned in fall, mainly so that they can easily fit in an indoor location to safely overwinter.

If you can't decide what to plant in that protected, semi-shady corner, you can't go wrong with tuberous begonia. However, tuberous begonia isn't a plant-it-and-forget-it plant. Keeping the plant alive and healthy requires a bit of extra attention. Read on for some tuberous begonia growing tips.

What is a Tuberous Begonia?

Types of tuberous begonias include upright or trailing varieties with single, double, or ruffled blooms in tropical shades of pink, yellow, orange, red, and white. The gold, purple, green, or burgundy leaves are nearly as attractive as the flowers.

Tuberous begonias are frost-tender. If you live in USDA plant hardiness zone 10 and above, you can grow tuberous begonias outdoors year-round. Otherwise, you'll need to dig the tubers and store them during the winter.

How to Grow Tuberous Begonias

Although tuberous begonias are shade-loving plants, they also require a bit of morning or late afternoon sunlight. A location in dappled or filtered light also works well, but the plants won't survive midday sun or heat. Begonias need moist, well-drained soil and are likely to rot in soggy conditions.

Tuberous begonias are available at most garden centers at spring planting time. However, you can also purchase tubers and plant them indoors six to eight weeks before the last expected frost date in your area.

Place the tubers an inch (2.5 cm) apart, hollow side up, in a shallow tray filled with moist potting mix and sand. Store the tray in a dark room where the temperature is about 65 degrees F (18 C). Water just enough to keep the potting mix moist. Watch for the tubers to sprout in about a month.

Plant each tuber into a pot when the shoots are about an inch (2.5 cm) long, then move the pots to bright light. You may need supplemental light to prevent the plants from becoming spindly.

Plant the begonias outdoors when you're sure all danger of frost has passed.

Tuberous Begonia Care

Water the plants regularly to keep the potting soil slightly moist. Provide a balanced, water-soluble fertilizer monthly during the growing season. Be sure to provide plenty of air circulation to prevent powdery mildew.

Use a sharp knife to cut spent blooms as soon as they fade.

Cut back on water in late summer, then dig the tubers when the foliage begins to turn yellow. Place each tuber in a small paper bag and store the bags in a cardboard box. Room temperatures for storage should be between 40 and 50 degrees F (4-10 C).

Check the tubers occasionally and discard any that are soft or rotten. Replant the tuberous begonias in spring.

The angel wing begonia is commonly named for the shape of its leaves. Numerous cultivars of the angel wing begonia houseplant offer many sizes and heights. Begonia x coralline, or the cane begonia, is known as one of the easiest begonias to grow inside. There is an angel wing begonia houseplant for most indoor situations. Growing angel wing begonias inside can provide a dwarf plant for the desk, or a large bushy, shrub-like floor plant, reaching 5 feet (1.5 m.).

Angel Wing Begonia Flowers

Learning how to grow an angel wing begonia indoors provides a houseplant with attractive year-round foliage. Speckled or streaked foliage appears on glossy green leaves with red tints or backing. An angel wing begonia houseplant blooms in pendulous clusters of flowers if located in the right area. Large clusters of flowers in a range of white, orange, pink, or red appear on the happy angel wing begonia houseplant. When growing angel wing begonias indoors, the right lighting and fertilization promotes flowering.

Angel Wing Begonia Care

The right angel wing begonia care encourages flowers to bloom throughout the year as well as healthy growth. Plant the angel wing begonia in a soil or soilless mix high in organic material. The angel wing begonia houseplant likes moist soil, but not soggy. Allow the soil to dry between waterings. Locate the angel win begonia houseplant in bright indirect light, in moderate temperatures. When growing angel wing begonias for the attractive foliage, flowers may not be desirable. If this is the case, place them in low light areas. Plants located in low light conditions will grow, but will not likely flower. Feed with a houseplant food high in nitrogen to promote larger leaves when growing angel wing begonias for foliage. Growing angel wing begonias for flowers requires a different type of fertilization than those grown for foliage. Angel wing begonia flowers need a fertilizer slightly higher in phosphorus than those grown just for foliage. Fertilize every two weeks. Depending on the cultivar, the angel wing begonia flowers in late winter through autumn. Some may bloom multiple times throughout the year. Repot yearly in spring. Move to a slightly larger pot each year. Add pebbles or broken pot shards in the pot to aid in drainage. Now that you've learned how to grow an angel wing begonia, experiment with different cultivars. All are attractive and low maintenance when grown in the right area.

Annual begonias, also called wax begonias, are a mainstay of the shade garden, bringing splashes of tropical color to otherwise dim corners of the landscape. We've got all the tips for growing begonias successfully. Read on for more.

Quick Facts about Annual Begonia:

• Botanical name: Begonia x semperflorens-cultorum
• Height: 6-12 inches (15-30 cm)
• Spread: 6-12 inches (15-30 cm)
• Sun exposure: shade to partial shade outdoors; sunny location indoors
• Soil requirements: moderately humus rich, well-drained moist soils
• Hardiness zones: USDA zones 9 or 10 and above, often grown as annuals
• When to plant: Start seeds indoors in January or February or 6-8 weeks before last spring frost date

Basic Wax Begonia Care

Wax begonia, also called wax leaf begonia or fibrous begonia, is a popular bedding plant. It provides colorful clusters of flowers and glossy foliage for shaded landscapes or bright interiors. Wax begonias are often grown as annuals and are considered the easiest begonias to grow. They bloom continuously from early spring. The flowers - red, pink or white - contrast with the waxy rounded leaves.

Though frequently grown as annuals - thus the common name annual begonias - they are actually a tender perennial that can overwinter in warm zones with frostfree winters. Whether treated as annuals or perennials, they require little maintenance once established. Wax begonia care is particularly easy since the plants tolerate heat, drought, and heavy shade.

Light & Water Requirements

Begonias are known as shade plants. However, for wax begonias, sun or shade locations can work. These are great compact flowering plants for dappled hade or part sun locations. Once the plants have established root systems, though, they can also thrive in some sun. Bright areas are ideal for begonia houseplants.

You should water fibrous begonias consistently over the growing season for best results. If you miss a few days, they are likely to survive since their thick and waxy leaves reduce water loss in hot weather. A thick layer of mulch in early summer helps them to hold in water.

Soil & Fertilizer Needs

When it comes to soil, begonias are a little needier. They require soil that drains well and do best in moist soils with a high amount of organic content. These plants are not heavy feeders, so if you want to use fertilizer, do so sparingly.

Problems, Pests & Diseases

Gardeners report few problems with their wax begonias as long as they get proper cultural care. However, those grown in soil with poor drainage or in a humid area without air circulation may be vulnerable to powdery mildew, botrytis, and stem rot. As far as insect pests go, keep an eye out for mealybugs and thrips. Slugs and snails are also potential problems.

Wax Begonia Propagation

You can propagate fibrous begonia in any of a variety of methods. They can grow from seed but germination is difficult and the seeds are small. Begonias can also be propagated by cuttings or division. However, most gardeners simply purchase plants in the springtime, especially if they are growing them as annuals.

Varieties of Wax Begonia

Anyone seeking a taller sort of begonia should check out 'Barbara Rogers,' a clumping variety that can grow to 5 feet (1.5 m) tall in USDA zones 7 - 9. It features white flowers all season long. 'Prelude White' also grows white flowers.

Other specialty varieties include 'Emperor Red' and ‘Senator Red’ for red flowers. The 'Party Pink' cultivar grows pink flowers and bronze leaves, while 'Whopper Rose Bronze Leaf' produces large pink flowers and bronze leaves.

How To Propagate Begonias Properly, According To Experts

Knowing how to propagate begonias can help you enjoy these well-loved plants in more places and for longer. There are many different ways to propagate plants, but some methods work better than others for specific plants. For begonias, try rooting stems and leaves for the best results.

Best Ways to Propagate Begonias

There are several options for propagating begonia plants. They include stem cuttings, leaf cuttings, seeds, and tuber cuttings. Here are the best methods for creating more begonia plants.

Stem Cuttings

When you learn how to root a begonia from a stem or shoot cutting, you will master one of the best methods for propagating begonias. This is the method of choice for getting a true plant from the parent. It’s also the easiest and most foolproof propagation option.

Take a 4 to 6 inch (10 to 15 cm) stem cutting just below a node. Remove the lower leaves, keeping two or three at the top of the cutting. You can dip the cut end in a rooting hormone to speed the process, but it isn’t necessary.

Prepare a seed tray or small container with drainage holes by filling it with moist potting soil or potting mix. Make a small hole in the mix and place the cutting in it. Press the soil around the cutting so it remains upright.

Keep your cutting in a warm location with good humidity. To keep it moist, you can seal the entire container in a plastic bag or cover it with plastic wrap. You should see the roots form within a few weeks. The plants can then be repotted.

Leaf Cuttings

You can propagate any type of begonia with a stem cutting, but only a few types work well with leaf cutting: They are rex, angel wing, and other types with larger leaves. Remove one leaf and treat the cutting as you would a stem cutting.

Seed Propagation

Propagation of begonias by seed takes more time and is more difficult than by cutting. If you have begonia seeds, begin them in January or February to get flowers in summer. Use a good quality seed starting mix. Press seeds into the surface of the moistened mix and add a layer of sphagnum moss over the top.

Cover the seed container with plastic to keep it humid and moist. The seeds will germinate within a few weeks if you can keep the temperature at a constant 70 degrees Fahrenheit (21 Celsius). Use a heating mat under the tray for consistency.

Once you have seedlings, thin them and provide bright light. Transplant larger seedlings to new pots. Place them outdoors only after hardening them off.

Tuber Cuttings

Taking cuttings of tubers is not the best way to propagate begonias because the pieces tend to rot easily. Reserve this method for saving tuberous begonias that have begun to rot. Cut off portions of the tuber that have not rotted and repot to grow a new plant.

When to Propagate Begonias

The best time to propagate begonias by cutting is in spring. Remove healthy new growth for the cutting, and you’ll have plenty of time to get roots and flowers during the growing season. To get flowers for summer by seed, start them in winter.

Frequently Asked Questions

Will Begonia Cuttings Root in Water?

Yes, you can root begonia cuttings in water, but be aware that it may take longer than rooting in soil or potting mix. For the quickest results, use a moist potting mix and rooting hormone.

Can You Propagate a Begonia With Just the Stem?

The best way to propagate a begonia by cutting is to take a stem with two or three leaves on the top and a node at the bottom of the cutting. 

The more than 1,000 species of begonia are part of a complicated classification system based on flowers, method of propagation and leaves. Some begonias are grown just for the fantastic color and shape of their foliage and either do not flower or the flower is unremarkable. Read on to learn more.

Classifying Begonias

Begonias are found wild in South and Central America and are native plants in India. They can be found in other tropical climates, and they propagate by a variety of means. The sheer variety of begonias has helped make them favorites of garden clubs and among collectors. Each of the six begonia sub classes has a unique leaf that can be used to facilitate identification.

Tuberous Begonia Leaves

Image by daryl_mitchell Tuberous begonia are grown for their showy flowers. They can be double or single petaled, frilled and a variety of colors. The leaves of a tuberous begonia are oval and green and grow about eight inches long. They are in a compact habit like a little bonsai shrub and grow from swollen soft stems.

The leaves are glossy and will die back when temperature drops or the season changes. The leaves should be left on so the plant can recharge the tuber for the following season's growth.

Cane Stemmed Begonia Leaves

Image by Jaime @ Garden Amateur

Cane stemmed begonia are grown mostly for their leaves which are heart shaped and gray-green. The plants are frost tender and oval, approximately six inches (15 cm.) long. The leaves are evergreen and the undersides will be mottled with silver and maroon. The leaves are carried on bamboo-like stems that can reach ten feet (3 m.) in height and may need staking. This type includes the "Angel Wing" begonias that have glossy green leaves shaped like delicate wings.

Rex-cultorum Begonia Leaves

These are also foliage begonias that are very nearly a hot house variety. They do best in a temperature of 70-75 F. (21-24 C.). The leaves are heart-shaped and are the most striking foliage producers. The leaves can be bright red, green, pink, silver, gray and purple in vibrant combinations and patterns. The leaves are slightly hairy and textured adding to the interest of the foliage. The flowers will tend to be hidden in the foliage.

Rhizomatous Begonia Leaves

Image by AnnaKika

The leaves on rhizome begonias are sensitive to water and need to be watered from below. Water will blister and discolor the leaves. Rhizome leaves are hairy and slightly warty and can come in several shapes. The multi-pointed leaves are called star begonias. There are some like Ironcross that have heavily textured leaves and the very frilly lettuce-like leaves such as beefsteak begonia. Leaves can vary in size from an inch (2.5 cm.) to nearly a foot (30.4 cm.).

Semperflorens Begonia Leaves

Semperflorens is also called annual or wax begonia due to their fleshy waxy leaves. The plant grows in a bushy form and is grown as an annual. Semperflorens is readily available for home gardeners and are prized for their constant and prolific blooming. Foliage can be green, red or bronze and some types are variegated or have white new leaves. The leaf is smooth and oval.

Shrub-like Begonia Leaves

Image by Evelyn Proimos

Shrub-like begonia are compact and tight clusters of 3-inch (7.5 cm.) leaves. The leaves are often dark green but may have colored spots. Humidity and bright light in winter increase the brightness of the foliage color. Begonias are known to be leggy so the foliage can be pinched off to encourage the shrub shape. The pinched leaves (with a little stem) can go on a bed of peat or other growing medium and will push roots from the stem point to produce a new plant.

Begonia plants, regardless of type, cannot withstand freezing cold temperatures and require appropriate winter care. Overwintering a begonia isn't always necessary in warmer environments, as winters are generally less severe. However, to ensure proper begonia care, you should be wintering over begonias as houseplants indoors if you live in areas prone to freezing temperatures.

When to Overwinter Begonias

The process of preparing the plants for winter generally begins in early fall. Tender species can be overwintered indoors as houseplants. Others may be allowed to die back naturally before the storage process can start. Learning how to overwinter begonias properly will be vital in ensuring you can enjoy your favorite varieties for seasons to come.

How to Overwinter Different Types of Begonias

There are three main types of begonias: tuberous, wax, and foliage. How you go about wintering begonias will depend significantly upon the type being grown, so make sure you know which type you have before going forward.

Tuberous Begonias

Tuberous begonia winter care is relatively simple. Each plant should be allowed to die back naturally after the first frost. Next, dig up the tubers and remove the stems and leaves down to the crown. Any loose soil should also be removed in preparation for a brief curing period that lasts approximately two weeks.

Spread begonia clumps on newspaper and leave them in a sunny area until thoroughly dry -- about a week. Once they have sufficiently dried, cut away any remaining foliage and gently shake off excess soil.

At this time, the tubers can be moved to storage. To prevent problems with fungus or powdery mildew while overwintering begonias, dust them with sulfur powder prior to storage. Experienced growers suggest packing each of the tubers into a cardboard box or paper bag that's been filled with sawdust or vermiculite. Begonias will overwinter best in a cool, dark, dry location, remaining frost-free throughout winter.

Wax Begonias

Some begonias can simply be brought indoors prior to the onset of cold weather for continual growth, such as with wax begonias. Since these plants don't have a period of dormancy, pots and containers will need to be moved inside before any chance of frost. If they’re in the ground, they can be carefully transplanted into containers first before being brought indoors. A high-quality potting mix will be essential, as begonias require rich soil with good drainage.

Before bringing a wax begonia indoors, however, be sure to treat it for insect pests or powdery mildew first. This inspection can be done by spraying plants or gently washing them with warm water and bleach-free dish soap.

Since bringing wax begonias indoors can cause plant stress, leading to leaf drop, it often helps to acclimate them beforehand. Move the begonias to a more shady area with partial sun for a week or two, then start bringing the plants inside for a couple of days out of the week. Finally, you can situate your wax begonias near a bright window, where they are able to receive ample indirect light.

Foliage Begonias

This type of begonia generally refers to those that have especially interesting or attractive foliage. Many of these species are evergreen within their native range, but can be grown annually in the home garden. Foliage begonias will require special care in winter. Experienced growers suggest bringing the plants indoors before the arrival of frost late in the season. Just like wax begonias, slowly acclimate your begonias to indoor lighting. Foliage begonias should be kept near a bright window and safely away from cold drafts or heating vents.

How to Care for Begonias in Winter

If you're growing potted begonia, overwintering care is minimal. If plants are kept warm and receive adequate light, they are likely to thrive. Containers should be kept consistently moist throughout the winter, with growers checking soil conditions at least once per week. Tuberous begonias in storage should also be checked regularly -- make sure to discard any plant that shows signs of rot, decay, or disease.

How to Revive Begonias Next Year

You can begin to move potted begonia plants outdoors in the spring when temperatures start to warm. Moving the plants indoors should be done gradually to harden off the plants and allow them to adapt to their new growing conditions slowly. As soon as all chances of frost have passed in the spring, the begonias can be moved to their permanent beds.

To revive tuberous begonias from storage, start by moving them to a warmer location or pot them into individual containers. The additional introduction of light will help to trigger new growth and give plants a jump start in the summer garden.

Begonias are a great way to brighten up the home and garden. Taking care of begonias is easy, especially when growing begonias from corms (or tubers). These charming plants can be easily started in a shallow tray of compost or damp peat in early spring. Once the plants have sprouted and weather permits in May or June, begonias can be moved outdoors. Let's take a look at caring for begonias.

Tips for Growing Begonia Plants from Corms

Begonia care begins with proper planting. As many people grow them as annuals, some may not be as familiar with begonia corms; therefore, it may be helpful to share some tips for growing begonia plants from corms. First, always plant begonia corms concave side up (depression on top) either slightly above or level with the compost/soil surface. Gently push the corms into place and once planted, water thoroughly. Make sure, however, that water does not sit in the depression of the corms, as this could lead to rotting. Place the tray in a warm windowsill or heated propagator. Growing begonias from corms requires warm temperatures, usually between 70 and 75 degrees F. (21-24 C.). Using a plastic cover is also acceptable as long as adequate ventilation is provided during begonia care.

Caring for Begonias

Taking care of begonias once the corms have sprouted is easy. When weather permits, begonias can be transplanted to the garden bed, spacing about 10 to 18 inches (25-46 cm.) apart. Likewise, they can be placed in containers spaced approximately 3 to 4 inches (8-10 cm.) apart. Leave plenty of room between plants for adequate circulation to prevent the possibility of developing mildew. When taking care of begonias, be sure to provide begonias with well-drained, organic soil and place them in a sunny or lightly shaded area. While begonias enjoy regular watering, be careful not to let them continually remain saturated, as this can also lead to problems with mildew as well as with fungus. Reduce watering once the leaves yellow in fall. In cold climates, begonia corms need to be lifted and stored in a cool, dry area over winter, usually in mid-October.

Additional Begonia Care

During the growing season, begonias may need to be protected from pests such as snails and slugs. These pests enjoy eating the young shoots and foliage. Caterpillars, thrips, aphids, and mealybugs can also attack begonia plants; however, with routine care, pests rarely become a problem. Tuberous begonias can be propagated easily through cuttings in spring or division. Divide begonias while dormant or when the shoots are still small. To prevent fungal diseases, dust them with Sulphur powder and allow them to dry before planting. Caring for begonias is well worth the limited effort required, as they do most of the work, providing endless color and beauty in the garden. Now that you have some tips for growing begonia plants from corms, caring for begonias grown from corms will be a snap.

Begonias are a popular houseplant. Some varieties of begonia houseplants are grown for their flowers while others are grown for their striking foliage. Growing begonias as houseplants only requires a little bit of knowledge in order to keep them looking their very best indoors. Let's take a look at how to care for begonias as houseplants.

Tips for Growing Begonia as Houseplants

The first thing to do when learning how to care for begonias indoors is to determine what kind of begonia you have. Begonias belong to one of three types -- tuberous, fibrous, and rhizomatous. 

Generally, fibrous and rhizomatous begonias make excellent houseplants while tuberous begonias can be grown as houseplants but have a harder time surviving due to the need for higher humidity and light than the other two kinds. Care of begonias indoors starts with the proper location. 

One of the tips for growing begonia as houseplants is to place them somewhere where they will get bright, indirect light and will get plenty of humidity. If the air in your house is dry, especially in the winter, it is a good idea to set your begonia houseplants on a shallow tray filled with pebbles and water. 

This will allow your growing begonias to get the humidity they need indoors without waterlogging the soil or exposing the leaves to excess moisture that could cause disease. Begonias grown indoors are especially susceptible to root rot and overwatering.

When you take care of begonias, make sure that you only water them when they need to be watered. Many experts suggest you actually wait until the plant shows signs of being dry, such as drooping leaves, before you water them. This will help prevent accidental overwatering, which is the main reason for begonias dying when grown indoors.

Also, when you water your begonia houseplant, make sure to water below the leaves in order to avoid inviting a fungal disease. Another tip for growing begonia plants indoors is that they are naturally pest-resistant. It is extremely rare to have a begonia develop a pest problem.

But, they are still susceptible to fungus issues, like powdery mildew, which is why it is best to keep the leaves dry. Growing begonias as houseplants can fill your home with lovely flowers and foliage. In the right location, begonia houseplants can flourish indoors.
