When to prune western maidenhair 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 western maidenhair fern
Trim all old fronds to soil level in late winter with clean scissors. During the growing season, snip individual dead or broken fronds at the base without disturbing the rhizome.
Western Maidenhair Fern is largely deciduous and naturally dies back each winter. Cut old fronds down to the ground in late winter before new growth emerges. During the growing season, remove any browned or damaged fronds at the base. No shaping is needed — the plant's habit is naturally elegant.

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.
