Shaggy Wood Fern problems — and how to fix them
Shaggy Wood Fern (Dryopteris cycadina) 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.
Scale damage on fronds
Though generally pest-free, scale insects can occasionally colonise the stems; check the distinctive dark stipe scales for unusual encrustations and treat with horticultural oil if found.
Frond scorch in exposed sites
Wind and direct sun cause frond edges to brown and curl; site in a sheltered spot with filtered light and mulch the root zone to retain soil moisture.
