Wallich's Wood Fern problems — and how to fix them
Wallich's Wood Fern (Dryopteris wallichiana) 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.
Slug and snail damage
Emerging croziers in spring are a prime target for slugs and snails; apply organic slug pellets or use copper barriers around new fronds when growth begins.
