When to prune male 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 male fern
Cut each old or dead frond at its base with scissors or pruners. Wear gloves — the base scales can irritate skin. Do not cut healthy green fronds or disturb the crown.
Male Fern needs no regular pruning as a houseplant. Remove old, yellowing, or dead fronds at the base throughout the year. A spring tidy before new fronds unfurl is the main maintenance task. The semi-evergreen nature means some older fronds persist through winter — remove them in early spring.

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.
