When to prune hammock fern in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune hammock fern
Snip dead or fully browned fronds at their base with clean scissors. If grown outdoors in mild climates where frost knocks back the fronds, cut all dead fronds back to ground level in early spring before new growth emerges.
Hammock Fern needs minimal pruning — remove dead or yellowed fronds at the base as they die to keep the plant tidy and healthy. No shaping is required. This terrestrial fern regenerates from a creeping rhizome, so old fronds naturally shed and new ones replace them throughout the growing season.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
