How To Care For Begonias As Houseplants


By: Heather Rhoades

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 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 water logging 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.

Rex Begonia Plant Profile

Rex begonias (Begonia rex) are tropical plants, prized for their colorfully patterned and intriguingly shaped leaves. Although they are at home in a shady garden, they are also popular as houseplants. Many people collect and display several varieties. Most rex begonias sold today are named hybrids, although they are not always labeled as such.

Rex begonia hybrids have been developed to have unusual markings, leaf shapes, and colors. The leaves grow on short leaf stalks, from the underground rhizome. The leaf edges and undersides are covered with short red hairs.

  • Leaves: Asymmetrical, the leaves are usually 4–9 inches long and variegated in shades of green, red, pink, purple, silver, and brown.
  • Flowers: The flowers are usually pink, but are small and incidental. It’s usually recommended that you cut the flowers and allow the plant's energy to go into growing the leaves. The flower stalks are usually removed to allow the plant's energy to be focused on growing leaves.

Cane Begonias

Cane begonias have stiff, upright stems that give them their common name, and produce clusters of dangling flowers in shades of red, orange, pink, or white year-round. Leaves are spotted, banded, or splotched with color, and wing shaped, giving them the once-common name angel wing begonias.

Landscape favorites include ‘Torch’ (red flowers) and ‘Alba’ (ever-blooming white). ‘Sophie Cecile’ is a reluctant bloomer, but its robust, five-foot foliage makes it a landscape standout. For South Florida gardeners these plants provide year-round interest however, in North Florida they usually die to the ground during the winter.


How to Grow Begonias Throughout the Season

Growth Habit: Tuberous begonias can be upright or trailing, depending on the variety. Tuberous begonias can be grown in the ground under trees or in shady parts of your garden, or in containers placed in shady areas of your porch, patio, or yard.

Staking: Trailing varieties of tuberous begonias are meant to creep, so they do not need staking. Upright tuberous begonias, however, can benefit from staking so the flower stems stand tall to make it easier to viewing the beautiful flowers. When upright varieties are 4 to 6 inches tall, place a narrow bamboo or metal stake in the soil near the main stem. Fasten the stem to the stake with plant ties or garden twine, being careful not to damage the stem. Add more ties to provide ongoing support as the plant grows.

Watering: Begonias need moist soil, but are very susceptible to rotting under wet conditions. Water slightly every few days, or when the soil dries out. Water less frequently if you have regular rain. Water containers of begonias more frequently, but always be cautious to not over water, or their stems might rot. Always water around the tuber, not directly on it, to repvent water from pooling in the tuber.

  • Tuberous and fancy begonia leaves can be stained and discolored by water. Avoid watering with cold water or tap water that is high in minerals, and when possible, use distilled water instead.

Fertilizing: Amend your soil with compost before planting begonias in the ground. Begonias are heavy feeders, so fertilize plants in the ground and in containers monthly with an organic balanced fertilizer (Look for 20-20-20 fertilizer mixes). For container begonias, use a liquid fertilizer, so the nutrients are more readily available.

Mulching: Since begonias are susceptible to rot due to wet conditions, mulching should be done cautiously. Use bark mulch around plants to preserve soil moisture and prevent weeds from growing. Keep mulch a few inches away from the succulent begonia stems to prevent them from rot. Begonias in containers don't need mulching.

Trimming & Pruning: To encourage fuller, bushier growth, pinch back newly-formed growth tips when they are about 3-6 inches long. Repeat monthly until mid-summer. For fewer, larger flowers, pinch off new young stem growth while leaving new buds to grow into flowers. Pinch back to the second healthy bud from the tip. Deadhead regularly to clean up the tuberous begonia's look, and to remove rotting old flowers that might infect the plants.

Brighten those gray days of winter by growing a few beautiful begonias indoors. Select from those with colorful foliage, uniquely shaped leaves or flowers.

You’ll have the greatest success growing fibrous rooted begonias that will flower in bright light and those with enlarged underground stems called rhizomes. These are grown for their leaves and tolerance of low light.

Grow your begonias in a warm location away from drafts of cold and hot air. Water thoroughly as the potting mix just starts to dry and only fertilize actively growing plants.

Place plants on gravel tray to increase humidity around the plant.

Increase flowering and leaf color intensity by adding artificial light to your growing location. Many new compact and stylish lights make it easy to add light while keeping with your indoor decor.

A bit more information: Rex begonia has long been grown indoors and more recently outdoors, for its colorful leaves. Its smaller stature makes it the perfect tabletop houseplant.
