When to prune venus 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 venus maidenhair fern
Snip individual dead stems cleanly at soil level with fine scissors. After severe dieback, cut all stems to within 2–3 cm of the soil, then keep the plant warm and humid to encourage new shoots.
Venus Maidenhair Fern needs light, regular tidying rather than formal pruning. Remove dead or browned fronds and stems at the base as they appear. If the plant suffers major dieback from low humidity or cold, cut all growth back to just above the soil in early spring — it will often regrow vigorously.

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.
