When to prune table 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 table fern
Snip dead or yellowing fronds at the base with clean scissors. For dense, bushy plants, remove the oldest outermost fronds first to improve light to the centre.
Table Fern (Pteris vittata) needs only light grooming. Remove old, discoloured, or dead fronds at the base to maintain a tidy appearance and encourage fresh growth. No hard cutting back is required. This fern grows vigorously when well-watered; simply clean out spent fronds as they appear.

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.
