Round-leaf Cape Primrose problems — and how to fix them
Round-leaf Cape Primrose (Streptocarpus rotundifolius) 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.
Botrytis grey mould
Fuzzy grey-brown patches on leaves or flowers, triggered by cool, damp, poorly ventilated conditions or water sitting on leaf surfaces. Remove affected tissue promptly and improve air circulation.
Crown rot
Overwatering or watering directly into the leaf crown causes the base to turn soft and brown. Always water from the edge of the pot or by bottom-watering, and ensure the compost drains freely.
