Indirect light is best for strong growth of Begonia. Too little light will weaken the growth and increase the chance of root rot or fungal issues. Avoid direct sunlight which can scorch the leaves.

When watering, it is important to avoid getting the leaves wet. One method is to let the plant absorb water through the soil from the bottom up by sitting it temporarily in a tray of water. Make sure that the top few inches of soil have been allowed to dry out in between waterings. If the soil is too dry, leaves will respond by curling and becoming crisp.
