Begonia 'Nonstop Rose Petticoat' problems — and how to fix them
Begonia 'Nonstop Rose Petticoat' (Begonia × tuberhybrida 'Nonstop Rose Petticoat') 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 coating on leaves in humid, crowded, still air. Space plants for airflow, avoid wetting foliage, and remove affected leaves; treat persistent cases with an appropriate fungicide.
Bud drop
Double buds drop in heat stress, erratic watering, or persistent damp. Provide light afternoon shade, keep moisture even, and shelter the soft blooms from heavy rain.
Tuber rot
Cold, wet compost or damp storage rots the tuber. Ensure sharp drainage, avoid overwatering, and store cleaned dormant tubers dry and frost-free over winter.
Botrytis (grey mould)
Grey fuzzy rot on the dense double flowers and stems in cool, damp, stagnant air. Improve ventilation, remove spent blooms and dead leaves promptly, and avoid overhead watering.
