When to prune adiantum venustum in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune adiantum venustum
Use clean scissors or snips to cut individual dead or brown fronds at the base. Do not shear the whole plant; remove only damaged material.
Adiantum venustum (Himalayan maidenhair) rarely needs pruning. Remove dead or frost-damaged fronds in early spring before new growth emerges. Cut individual tatty fronds back to the base with clean scissors. Beyond that, leave it alone — the delicate fronds are best enjoyed undisturbed.

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.
