Begonia dichroa

The polka dot begonia typically needs a balance of sunlight and shade to grow properly. It does well in lower-light spots, reflecting its native setting beneath taller plants. Excessive sunlight can cause leaf burning, while too little light may impede growth and diminish leaf vigor.

The polka dot begonia's native growing conditions involve specific temperature needs. It does best in temperatures of 68 to 100 ℉ (20 to 38 ℃). In summer it can withstand higher heat, but should be kept out of direct sunlight. In winter it prefers 60 to 70 ℉ (15.5 to 21 ℃) and may need a humidifier to keep humidity at the right level.

Polka dot begonia needs the most fertilizer during its active growth period, which takes place mainly in spring, summer, and early fall. Fertilizing supplies essential nutrients that the soil might lack, supporting healthy root and stem growth and encouraging the attractive foliage that defines this plant.

When repotting Polka dot begonia, choose a pot 1–2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring that the root ball is slightly lower than the rim of the flower pot. Water thoroughly after repotting and place in a warm spot with indirect sunlight.
