Troubleshooting
Angel Wing Begonia problems — and how to fix them
Angel Wing Begonia (Begonia coccinea) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
The most common issue: white powdery patches on leaves caused by high humidity with poor air circulation. Improve airflow, keep foliage dry, and remove affected leaves; treat with a baking-soda or fungicidal spray.
Leaf drop and bud drop
Sudden temperature swings, cold drafts, or letting the soil fully dry out trigger dropping leaves and flower buds. Keep it above 55F (13C) away from drafts and maintain even moisture.
Yellowing leaves and root rot
Usually from overwatering or poor drainage leaving the roots waterlogged. Let the top inch or two dry between waterings and ensure the pot drains freely.
Crispy brown leaf edges
Often a sign of low humidity or too much direct sun. Raise humidity with a pebble tray or humidifier and move the plant out of harsh midday rays.
Leggy, sparse growth
Too little light or skipped pruning causes long bare canes. Move to brighter indirect light and pinch or prune stem tips to encourage bushier, fuller growth.
