Begonia × tuberhybrida 'Nonstop Rose' problems — and how to fix them

Begonia × tuberhybrida 'Nonstop Rose' (Begonia × tuberhybrida 'Nonstop Rose') 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.

Tuber and stem rot

Overwatering, planting too deep, or wetting the crown causes the fleshy stem to collapse. Plant tubers shallow, water at the base, and ensure sharp drainage.

Powdery mildew

White coating in still, humid air. Space plants, improve ventilation, and remove affected leaves; treat with a suitable fungicide if persistent.

Bud drop

Flower buds fall before opening due to heat stress, drought, or sudden moisture swings. Keep cool, shaded, and evenly watered.

Flower scorch

Direct midday sun browns the delicate double petals. Move to dappled or afternoon shade.
