Angel wing begonia (Begoniaceae) is a lovely indoor plant, beautiful enough to delight serious gardeners but easy enough for novices. Although the huge pairs of colorful, angel-shaped wings are the plant's strong point, an added benefit is the delicate, pale pink blooms that dangle gracefully from the stems. Angel wing begonias are fast growing plants, but the plants can easily be trimmed if they grow out of control.
Place the angel wing begonia in a sunny window during the winter months. During the remainder of the year, place the plant in moderate light away from hot, sunny windows.
Water the plant until water just begins to drip from the drainage hole in the bottom of the pot. Pour out any water remaining in the drip tray under the pot, as allowing the pot to stand in water can cause the plant to rot. Don't water the plant again until the top inch of the potting soil feels dry to the touch.
Fertilize angel wing begonia every month, using a liquid houseplant fertilizer. When grown slows during fall and winter, fertilize the plant every other month. Read the label for specific instructions before applying the fertilizer.
Keep the angel wing begonia in a warm room, with daytime temperatures between 65 and 70 degrees F, and nighttime temperatures 5 to 10 degrees cooler.
Pinch off leaves if the plant begins to look straggly or leggy. You can also cut the plant down to just a few inches tall, leaving shoots of varied heights to give the plant a natural look. The plant will grow back soon, and will have a neat, natural shape.
