Troubleshooting
Dryopteris dilatata problems — and how to fix them
Dryopteris dilatata (Dryopteris dilatata) 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.
Frond scorch in sun or wind
Hot sun and drying winds brown the broad fronds. Site in sheltered shade and mulch the root zone.
Tatty winter foliage
Semi-evergreen fronds become ragged by late winter. Cut old fronds to the ground in early spring before new croziers unfurl.
Drought stress on young plants
Newly planted ferns wilt if the soil dries. Water regularly until the deep crown establishes, then drought tolerance improves.
Vine weevil in containers
Pot-grown plants can suffer root damage from vine weevil larvae. Inspect roots and use biological controls if growth weakens.
