When to prune crown staghorn 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 crown staghorn fern
Trim only fully dead or rotting fertile fronds at their base using sterile scissors or a clean knife. Shield fronds, even when brown, must never be removed as they are part of the plant's root system.
Crown Staghorn Fern (Platycerium coronarium) needs almost no pruning. Its distinctive pendant fertile fronds and papery shield fronds should be left intact. Only remove fertile fronds that have died completely and are decomposing. This is a large, slow-growing tropical epiphyte — unnecessary cutting sets it back significantly.

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.
