Begonia sutherlandii problems — and how to fix them
Begonia sutherlandii (Begonia sutherlandii) 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
Highly mildew-prone from late summer; white film on leaves in humid, crowded conditions. Improve airflow and avoid overhead watering.
Tuber rot
Wet compost during the dormant winter season rots the tuber; keep it barely moist and frost-free until spring.
Stem and leaf scorch
Hot direct sun and drying wind crisp the foliage; site in bright shade with shelter.
Premature dormancy
Sudden cold, drought stress, or shortening days trigger early dieback; this is natural, so reduce water and let the tuber rest.
