Troubleshooting
Begonia schmidtiana problems — and how to fix them
Begonia schmidtiana (Begonia schmidtiana) 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 film on the hairy leaves in humid, stagnant air. Improve circulation, keep the foliage dry, and remove affected leaves to limit spread.
Bud or flower drop
Sudden drops in humidity, temperature swings, or inconsistent watering can shed buds. Keep conditions steady, warm, and moderately humid.
Brown leaf edges
Dry air or salt build-up from over-feeding. Raise humidity, flush the soil occasionally, and dilute fertiliser more.
Root rot
Waterlogged mix rots the fine roots, causing wilting and collapse. Use a free-draining mix and let the surface dry before watering again.
