Begonia 'Nonstop Joy White' (Begonia × tuberhybrida 'Nonstop Joy White') 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 coating on leaves in crowded, humid, still conditions. Space plants for airflow and avoid wetting the foliage.
Botrytis (grey mould)
Soft grey rot on stems and faded flowers in cool, damp weather. Deadhead spent blooms and remove damaged tissue promptly.
Bud and flower drop
