Troubleshooting
Alpine Butterwort problems — and how to fix them
Alpine Butterwort (Pinguicula alpina) 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.
No winter dormancy
This is a temperate, cold-climate species. Kept warm year-round it fails to form its hibernaculum and gradually dies. Give it a cold (near-freezing), barely-moist winter rest.
Acidic-mix decline
Unlike tropical pings, it dislikes pure peat. In an overly acidic, peaty medium it sulks; add grit, sand and a little limestone for the calcium it prefers.
Crown rot in stagnant warmth
Hot, humid, airless conditions rot the soft rosette. Keep it cool with airflow rather than enclosed and warm.
Mineral damage from hard water
Tap-water salts harm the roots and brown the leaves; water only with rainwater, distilled or RO water.
Prevent alpine butterwort problems before they start
Most alpine butterwort issues are care-mismatch, not bad luck. Dial in the basics:
