Troubleshooting
Cretan Climbing Fern problems — and how to fix them
Cretan Climbing Fern (Lygodium microphyllum) 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.
Tangled, unruly growth
The indefinitely extending fronds twine into a mat if not trained. Provide a trellis early and guide or trim the leading tips.
Browning, crispy leaflets
Low humidity or the soil drying out. Raise humidity and keep moisture steadier.
Yellowing fronds
Waterlogged roots or low light. Improve drainage and brighten the position.
Escape and invasiveness
Spores spread easily and the plant is invasive in warm regions. Keep it contained indoors and bag spent fronds rather than composting outdoors.
