Troubleshooting
Begonia incarnata problems — and how to fix them
Begonia incarnata (Begonia incarnata) 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.
Leggy, sparse stems
Stretched canes with wide gaps between leaves indicate too little light. Move to brighter indirect light and pinch growing tips to encourage branching and density.
Powdery mildew
White powdery film on leaves in stagnant, humid air. Increase airflow, avoid wetting foliage, remove affected leaves, and treat with a suitable fungicide if it spreads.
Root and stem rot
Yellowing, wilting, and a soft stem base follow overwatering or poor drainage. Use an airy mix, let the surface dry between waterings, and repot if roots are mushy.
Bud or flower drop
Sudden temperature swings, drafts, or drying out can cause buds to abort. Keep conditions steady and the rootball evenly moist during budding.
