When to prune tiger 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 tiger fern
Cut individual fronds at the base with sterilised scissors. For a full rejuvenation, trim all fronds back to 2–3 inches in early spring, ensuring the growing crown is not damaged.
Tiger Fern (Nephrolepis exaltata 'Tiger Fern') needs routine removal of dead or browning fronds throughout the year. Cut spent fronds back to the base to keep the plant tidy and allow light and air into the centre. A spring cut-back can rejuvenate a congested plant and prompt a fresh flush of growth.

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.
