Begonia Coccinea (Angel Wing or Cane-stemmed begonias) / Begonia Rex (Fancy Leaf begonia)
Native to South America and India
Medium to bright filtered. Avoid direct sun, which scorches leaves.
18–24°C (spring-fall). Give a rest at 13°C (winter).
Higher. For extra humidity (spring and summer only): place pot on moist pebbles in a tray, group with other plants, or, introduce a humidifier. Do not mist leaves, which encourages powdery mildew.
Weekly. Water moderately (spring-fall) and allow moist potting mix to dry within top 1-2”. Water more sparingly (winter) and allow barely moist mix to dry out halfway. Always check moisture level before watering. Aerate mix to improve its condition.
Every 2 weeks (spring-fall). Use organic houseplant fertilizer, according to packaging instructions.
Every 1-2 weeks, rotate plant to ensure even growth. Trim droopy or unsightly leaves with sterile shears as needed.
Potting and Repotting
Peat-based potting mix. Every 1 -2 years (spring), move plant into a planter 1-2” larger (diameter and depth); or, repot in the same planter, using new potting mix, after cleaning planter and partially trimming back roots and foliage. Tap to settle roots but avoid firming soil. Top dress annually, once maximum convenient planter size reached.
Special Points/Common Problems:
- Crinkly or brittle leaves may suggest poor humidity or exposure to direct sunlight. Adjust humidity, placement or window coverings accordingly.
- Dry or droopy leaves often suggest underwatering, while yellowing or mushy leaves often suggest rot from overwatering. Adjust frequency or amount of water accordingly.
- Spots on leaves are often fungal. Remove affected leaves and treat with fungicide at regular intervals, according to package instructions.
- May produce insignificant flowers. Once flowers fade, trim stalks to their base.
