When to prune wallich's 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 wallich's staghorn fern
If a fertile (antler) frond dies back completely and is rotting, cut it cleanly at its base with sterile scissors. Never cut or remove the brown shield fronds — they are functional, not dead.
Wallich's Staghorn Fern needs almost no pruning. Never remove the brown, papery shield (basal) fronds — they protect roots and anchor the plant to its mount. Only trim dead or heavily damaged fertile fronds if they are rotting or causing hygiene issues. Leave healthy growth entirely alone.

Prune wallich's staghorn fern in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

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.
