Product Description:
Among the various types of begonias, Begonia rex is one of the most beautiful and dramatic plants. Sometimes called painted-leaf begonias or fancy-leaf begonias, these plants are known for their variegated leaves. They frequently have large leaves (up to 6 inches long) that are brightly colored in various shades of green, red, silver, and even purple. These plants are grown almost exclusively for their foliage their blooms tend to be small and less showy and many growers pinch off blooms to maintain breathtaking leaf displays.
Light:
Rex begonias like bright, indirect light year-round. Because they are not aggressive bloomers, they can tolerate less light than other begonias and will thrive under fluorescent lights.
Soil:
Airy, light, fast-draining soil is best for rex begonias.
Water:
Rex begonias require regular water, but be careful not to overwater them.
Temperature and Humidity:
Rex begonias do best in moderate temperatures (60 to 70 degrees Fahrenheit) and moderately high humidity (around 50 percent). Growth will slow in freezing temperatures and some types of begonias go into a dormant period during the winter due to lack of light.
Fertilizer:
Use liquid fertilizer weekly at quarter strength or at half strength every two weeks.
Propagating Rex Begonia:
Rhizomatous begonias such as the rex begonia can be easily propagated by rhizome during repotting. Almost all begonia species will readily sprout from leaf-tip cuttings. A rooting harmone can help the cuttings sprout.
Potting and Repotting Rex Begonias:
When the rhizome begins to butt up against the sides of the pot, however, it’s time to repot into a fresh pot with fresh soil. Divide the rhizome when repotting to increase your plant stock.
