Troubleshooting
Palm Leaf Begonia problems — and how to fix them
Palm Leaf Begonia (Begonia luxurians) 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, damp air. Improve airflow, avoid wetting foliage, and keep humidity high without misting directly.
Root and stem rot
Caused by soggy, poorly drained soil or overwatering. Use a free-draining mix, let the top few centimetres dry between waterings, and never leave the pot sitting in water.
Spider mites
Fine webbing and stippled, pale leaves in dry indoor air. Raise humidity, rinse the foliage, and treat with insecticidal soap or neem if infestations persist.
Crispy brown leaf edges
A sign of low humidity, dry soil, or hot direct sun. Increase ambient humidity, keep watering consistent, and move the plant out of harsh light.
Leaf drop
Sudden shedding usually follows cold draughts, temperatures below 10C, or a sharp change in conditions. Keep it warm, draught-free, and away from cold windows in winter.
Legginess
Sparse, stretched stems develop in low light or without pruning. Give brighter indirect light and pinch or prune the canes to encourage bushier growth.
