When to prune leatherleaf 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 leatherleaf fern
Cut individual dead or yellowing fronds at their base with clean scissors or pruning shears. Do not cut back healthy fronds — new growth is slow to replace them.
Leatherleaf Fern (Rumohra adiantiformis) is long-lived and slow to produce new fronds, so prune very sparingly. Only remove truly dead or yellowing fronds at the base. Healthy dark-green fronds can last for months and should not be cut back. Minimal intervention keeps this plant at its best.

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.
