When to prune giant 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 giant staghorn fern
Inspect regularly and use clean scissors to remove only fronds that are entirely dead (black or completely desiccated). Do not cut or peel away brown shield fronds — their colour is normal and functional.
Giant Staghorn Fern (Platycerium superbum) requires no pruning. Never remove the brown, papery shield fronds at the base — they are living tissue that anchors the plant and absorbs water and nutrients. Remove only fully dead, black, or rotting fronds. Cutting shield fronds will harm or kill the plant.

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.
