Troubleshooting
Begonia scharffii problems — and how to fix them
Begonia scharffii (Begonia scharffii) 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
White dusty patches on leaves in stagnant, humid air. Improve airflow, avoid wetting foliage, and remove affected leaves promptly.
Stem and crown rot
Soft, blackened stem bases from overwatering or cold, wet soil. Let the surface dry between waterings and use a free-draining mix.
Leggy, sparse growth
Long bare stems result from too little light. Move to brighter indirect light and pinch growing tips to encourage branching.
Brown crispy leaf edges
A sign of low humidity or dry air near heaters. Raise ambient humidity with a pebble tray or humidifier.
