Begonia 'Non-Stop Rose' problems — and how to fix them
Begonia 'Non-Stop Rose' (Begonia × tuberhybrida 'Non-Stop 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 rot
Soft, mushy tubers from overwatering or planting too deep. Set the tuber hollow-side up at the surface, water sparingly until growth establishes, and ensure sharp drainage.
Powdery mildew
White powdery film on leaves in humid, crowded conditions. Improve airflow, avoid overhead watering, and remove affected foliage.
Botrytis (grey mould)
Grey mould on flowers and stems in damp, cool weather. Remove faded blooms and debris and increase ventilation.
Bud drop
Flowers dropping before opening due to erratic watering, temperature swings or moving the plant. Keep moisture steady and the location stable.
