Troubleshooting
Boliviensis Begonia problems — and how to fix them
Boliviensis Begonia (Begonia boliviensis) 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 powdery growth on leaves in humid, crowded, poorly ventilated conditions. Improve airflow, avoid wetting foliage, and remove affected leaves; this species is fairly resistant but not immune.
Dried-out baskets
Hanging baskets dry rapidly in summer sun and wind, causing wilting and flower loss. Check moisture daily, water thoroughly, and consider a basket with a water reservoir in exposed spots.
Tuber rot
The tuber rots in cold, wet compost or damp storage. Ensure sharp drainage, never let pots stay waterlogged, and store cleaned dormant tubers dry and frost-free over winter.
Frost damage
Even a light frost blackens and kills the soft top growth. Bring plants under cover before the first frost, then dry off and store the tuber until spring.
