Troubleshooting
European Chain Fern problems — and how to fix them
European Chain Fern (Woodwardia radicans) 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.
Frost damage to fronds
Fronds blacken and collapse after temperatures below about -3°C. In frost-prone UK gardens, protect the crown with a thick dry mulch of straw or bracken in autumn and wrap with horticultural fleece during hard frosts.
Frond tip browning from low humidity or wind
Cold or drying winds quickly damage the large frond tips. Grow in a sheltered microclimate and maintain high humidity; erect a temporary windbreak if necessary in exposed maritime gardens.
