Troubleshooting
Utricularia alpina problems — and how to fix them
Utricularia alpina (Utricularia 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.
Heat and low humidity stress
This cool cloud-forest species sulks and collapses in hot, dry rooms. Provide cooler temperatures and high humidity, ideally in a terrarium.
Waterlogging the epiphytic roots
Unlike terrestrial bladderworts it resents being permanently sodden. Keep the sphagnum moist and airy rather than standing deep in water long-term.
Mineral injury from tap water
Hard water damages the plant. Use only rain, distilled or reverse-osmosis water.
Sphagnum breakdown and rot
Old, decomposed sphagnum goes airless and rots the stolons. Refresh the medium periodically and keep airflow good.
Prevent utricularia alpina problems before they start
Most utricularia alpina issues are care-mismatch, not bad luck. Dial in the basics:
