Troubleshooting
Shoestring Fern problems — and how to fix them
Shoestring Fern (Vittaria lineata) 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.
Shrivelled, browning fronds
The classic sign of insufficient humidity or drying out. Keep the mount damp and humidity high, ideally in an enclosed case.
Crispy frond tips
Caused by hard water or dry air. Switch to rainwater or distilled water and raise ambient humidity.
Rot at the rhizome
From stagnant, waterlogged moss with poor airflow. Ensure good ventilation and keep the medium moist but not sodden.
Sparse or stalled growth
Often too little humidity or too cold. Maintain warmth above 18°C and consistently high moisture to encourage new fronds.
