Kellerman's Begonia problems — and how to fix them
Kellerman's Begonia (Begonia kellermanii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Stem rot at the base
Overwatering or poorly draining compost leads to basal stem collapse, especially in cooler months; reduce watering frequency significantly in winter and ensure pots drain freely.
