5' rex begonia

  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. Water: Rex begonias like even amounts of water but hate being overwatered. They also thrive on humidity but don't like direct misting, which encourages powdery mildew. Temperature: They like average to warm (and humid). They cannot tolerate freezing, and some types of rex begonias go into a dormant period during the fall. Soil: Airy, light, fast-draining soil is best. Fertilizer: Use liquid fertilizer weekly at quarter strength or biweekly at half strength.
