When to prune fragrant 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 fragrant maidenhair fern
Use fine scissors to cut dead or brown stems at soil level. For a full reset in spring, cut all stems back to 2–3 cm above the soil — the rhizomes will regenerate new fronds within weeks in warm, humid conditions.
Fragrant Maidenhair Fern benefits from cutting back leggy or dead stems to encourage a flush of fresh, delicate new growth. In spring, trim the whole plant back by about half if it looks sparse or tired. Year-round, remove any brown or crisped stems at the base promptly.

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.
