When to prune lady 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 lady fern
Snip individual spent fronds at their base with clean scissors. Work carefully around the crown to avoid damaging emerging croziers (fiddleheads) in spring.
Lady Fern requires little pruning as a houseplant. Remove old, yellowing, or damaged fronds at the base throughout the year. A spring clean-up before new fronds emerge helps the plant look its best. Do not cut back the whole plant — ferns do not regenerate from bare crowns like herbaceous perennials.

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.
