When to prune peacock 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 peacock fern
Snip individual dead or brown fronds at the base with clean scissors. Do not cut into healthy green growth.
Peacock fern needs minimal pruning. Remove dead, brown, or damaged fronds at their base as they appear to keep the plant tidy and prevent rot. No structural pruning is required — cutting healthy stems disrupts the dense, creeping mat that makes this plant attractive. Focus on moisture and humidity over any cutting.

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.
