Why Angel Wing Begonias Drop Healthy Leaves

If your angel wing begonia is shedding healthy-looking leaves, systematically check three common causes:

1. Pest Inspection

Examine leaf undersides and stem junctions for:

• Mealybugs: white, cottony clusters
• Whiteflies: tiny white insects that flutter when disturbed
• Spider mites: fine webbing between leaf stems, stippled foliage

2. Watering Issues

Overwatering is a primary cause of leaf drop. Allow the top inch of soil to dry before watering thoroughly. Ensure pots have drainage holes and never sit in water-filled saucers, which causes root rot.

3. Environmental Stress

Sudden temperature changes, cold drafts, low humidity, or recent repotting can trigger leaf abscission. Maintain stable conditions: 65–75°F, moderate humidity, bright indirect light.

Treatment

Address pests with insecticidal soap or neem oil. Adjust watering. Increase humidity with a pebble tray. The plant should stabilize and produce new growth once stressors are removed.
