African Liana Sundew problems — and how to fix them
African Liana Sundew (Triphyophyllum peltatum) 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.
Failure to enter carnivorous phase
The plant only produces glandular, insect-catching leaves when phosphorus is limiting — growing it in nutrient-rich compost or with regular fertiliser suppresses carnivory entirely; use a lean, peat-based medium and withhold phosphorus supplements.
Stem die-back from low humidity or cold
Any drop in humidity below 60% or temperatures below 18 °C can trigger stem die-back and leaf drop; this tropical liana is intolerant of chilling and must be maintained in a consistently warm, humid environment.
