When to prune cretan brake 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 cretan brake fern
Cut individual dead or yellowed fronds off at soil level using clean scissors. Avoid cutting into the central crown. If the plant becomes very congested after years of growth, divide it at repotting rather than pruning.
Cretan Brake Fern needs light, routine maintenance pruning only. Remove individual fronds that have died, browned, or become tattered at the base. No hard pruning or shaping is needed — the plant regenerates steadily from the crown. Keeping spent fronds removed encourages fresh growth and improves appearance.

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.
