Troubleshooting
Begonia conchifolia problems — and how to fix them
Begonia conchifolia (Begonia conchifolia) 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 powdery patches on leaves from damp foliage and poor airflow; water at the soil line, improve ventilation and avoid misting.
Rhizome and root rot
Mushy stems and yellowing from overwatering or a heavy, water-retentive mix; let the surface dry between waterings and use a free-draining medium.
Leggy, sparse growth
Stretched stems and faded leaves indicate too little light; move to brighter indirect light and pinch tips to encourage branching.
Brown crispy leaf edges
Low humidity or dry air near heaters; raise humidity with a pebble tray and keep away from radiators and cold drafts.
