Large-Leaved Butterwort problems — and how to fix them
Large-Leaved Butterwort (Pinguicula macrophylla) 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.
Bulb rot in winter dormancy
Overwatering during the dormant bulb phase is the primary cause of plant loss. Once the carnivorous leaves fully die back, reduce watering to once every 2-3 weeks and ensure the pot drains freely. Store the pot on its side if rot persists.
Failure to emerge from dormancy
If the bulb does not sprout new leaves in spring, the dormant bud may have desiccated completely or rotted. Check for a firm, green-white bud; if soft and brown, the plant has likely died. Prevent by keeping the substrate very slightly damp (not dry) throughout dormancy.
