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 leathery polypody

Snip individual dead or damaged fronds at their base using clean scissors. Leave the rhizome and all healthy fronds untouched.

Leathery Polypody rarely needs pruning. This western North American epiphytic fern grows from a slow-creeping rhizome and does not branch or fill out in response to cutting. Remove only fronds that have died or been physically damaged. The rhizome should never be cut — it is the plant's growing engine.

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.
