Troubleshooting
straight-leaved butterwort problems — and how to fix them
straight-leaved butterwort (Pinguicula rectifolia) 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.
Crown rot
Caused by water pooling in the rosette centre or poor air circulation. Water only at soil level and ensure the pot drains freely. Increase airflow around the plant.
Leaf scorch or bleaching
Direct midday sun through glass magnifies heat and burns the delicate sticky leaves. Move to filtered light or add a sheer curtain. Leaves that have turned pale or papery will not recover but new growth will be healthy.
Failure to transition to winter phase
If light and warmth are maintained artificially through winter, the plant may not produce its small succulent resting leaves. Allow temperatures to drop to 12–15°C and reduce watering in autumn to trigger the seasonal cycle correctly.

Most straight-leaved butterwort issues are care-mismatch, not bad luck. Dial in the basics:
