Vandeleur's Cape Primrose problems — and how to fix them
Vandeleur's Cape Primrose (Streptocarpus vandeleurii) 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.
Fungal crown and root rot
The plant's large leaf prevents surface inspection of the soil; overwatering or water trapped under the leaf causes rapid basal rot. Use exclusively bottom-watering and ensure perfect drainage.
Failure to flower
This monocarpic species flowers only once, and inadequate light or insufficient pot size can delay or prevent flowering entirely. Provide consistent bright indirect light and pot on only when the plant is rootbound to encourage flowering stimulus.
