When to prune silver dollar 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 silver dollar maidenhair fern
Cut dead fronds cleanly at the base with clean scissors. If the plant has suffered a full die-back from drought or low humidity, cut all stems to soil level and keep the rootball moist.
Adiantum peruvianum needs little pruning. Remove dead or browning fronds at the base as they appear to keep the plant tidy and encourage fresh growth. If fronds die back after stress — common in dry indoor air — cut all stems to the base and the plant will often resprout. No shaping is needed.

Pruning silver dollar maidenhair fern in the UK — FAQ
When should I prune silver dollar maidenhair fern in the UK?
Prune silver dollar maidenhair fern in spring, once growth resumes. 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.
Is it illegal to prune silver dollar maidenhair fern in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check silver dollar maidenhair fern for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
