Water only when soil is dry, and water sparingly in winter.
Keep plant in a bright spot to encourage bright leaf colour and flowering, but away from direct sunlight to avoid leaf scorch. A bright east or north-facing window is best.
Average room temperature should be 16°C in winter.
Begonias originate from the tropics, so they love humidity. Allow good air circulation.
Repot Begonia only when root-bound, using a pot no more than two inches in diameter bigger than its current size.
Take stem cuttings in spring or early summer.
