Begonia 'Picotee Lace Pink' (Begonia × tuberhybrida 'Picotee Lace Pink') 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.
Botrytis (grey mould)
Double blooms hold moisture and rot in cool, damp weather. Deadhead promptly, improve airflow and avoid overhead watering.
Powdery mildew
White coating on leaves in humid, crowded, still conditions. Space plants and keep the foliage dry.
Petal scorch
