Wendland's cape primrose problems — and how to fix them
Wendland's cape primrose (Streptocarpus wendlandii) 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.
Basal rot at the mid-vein
Water pooling at the base of the massive single leaf causes rotting of the central midrib. Water around the pot rim, not the centre; use a very free-draining mix.
Botrytis (grey mould)
The large leaf surface is vulnerable in humid, still conditions. Ensure airflow, remove any decaying leaf material promptly, and avoid wetting foliage when watering.
Very slow to flower
The monocarpic cycle can take 2–3 years from seed to flowering. Maintain bright indirect light and consistent feeding to reach flowering stage. The plant will naturally flower when physiologically ready.
