Troubleshooting
Taiwan Felt Fern problems — and how to fix them
Taiwan Felt Fern (Pyrrosia polydactyla) 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.
Rhizome rot from overwatering
The most common cause of failure. The creeping rhizome rots rapidly in soggy conditions. Use a very free-draining mix, ensure the pot has drainage holes, and allow the medium to partially dry between waterings.
Loss of felt texture (smooth fronds)
Young fronds occasionally emerge with less stellate felt in very low light. Ensure adequate bright indirect light. The distinctive felt coating is a diagnostic feature — plants in good conditions produce it consistently.
Root mealybugs
Mealybugs can colonise the rhizome and roots in the warm, sheltered conditions of an indoor pot. If growth stalls without obvious cause, unpot and inspect the rhizome. Treat by washing roots and drenching with diluted neem oil.
