When to prune regal elkhorn 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 regal elkhorn fern
Use sterilised scissors to cut away only entirely dead or blackened fronds. Leave all brown shield fronds untouched — their colouration is normal and removing them stresses or kills the plant.
Regal Elkhorn Fern requires no routine pruning. Like all Platycerium, its brown shield fronds are living and must never be removed — they protect the root ball and feed the plant. Only remove fronds that are completely dead and rotting. This plant manages itself; human intervention usually does more harm than good.

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.
