Collapsed, browning fronds
The most common cause is the soil drying out. This fern needs constant moisture; water generously and consider a boggier site.
Sun scorch
Direct sun on insufficiently wet soil bleaches fronds. Provide shade or ensure roots stay in moist to wet ground.
Wind damage to upright fronds
Its tall, slender fronds catch the wind and flop or tear. Plant in a sheltered position among other vegetation for support.
Slugs and snails
Damp conditions favour molluscs that nibble emerging croziers. Use barriers or wildlife-safe controls in spring.
