Crested Buckler Fern problems — and how to fix them
Crested Buckler Fern (Dryopteris cristata) 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.
Slugs and snails
Tender young croziers emerging in spring are highly attractive to slugs and snails; use iron-phosphate slug pellets (pet-safe) or copper tape barriers around crowns and hand-pick at dusk in wet weather.
Frond tip browning in dry conditions
D. cristata is a wetland specialist and rapidly develops brown, crispy frond tips if the soil dries out even briefly; mulch thickly and irrigate during any dry spells to prevent this.
