When to prune carex pendula in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune carex pendula
Pull or cut dead and discoloured leaves at the base, close to the crown, using scissors or a sharp knife. Remove spent flowering stems after seeds have dispersed if self-seeding is a concern — this species self-seeds freely.
Carex pendula (pendulous sedge) is largely self-maintaining but benefits from removing old, brown or tatty leaves and spent flower stems to keep it looking tidy. Cut them back individually at the base with scissors or a knife. Avoid hard overall shearing, which can damage the evergreen crown and spoil its graceful arching form.

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.
