When to prune cotton candy 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.

Cotton Candy Fern needs routine removal of dead or browning fronds to stay looking its best. Cut spent fronds at the base as they appear. An annual spring cut-back can refresh an older, congested plant. Like other Boston Fern cultivars, it does not require shaping — just keep dead growth removed.

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.
