When to prune bronze sedge 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 bronze sedge
Use scissors or shears to trim dead tips and outer tatty leaves. A light overall trim — removing the top third of the foliage — can neaten the plant; do not cut below the green foliage into the crown.
Bronze Sedge (Carex comans 'Bronze') is an evergreen, low-maintenance sedge. It needs only light tidying. In late winter or early spring, remove dead brown tips or untidy outer leaves with scissors. You can also give the whole clump a light trim to neaten it, but avoid cutting into the crown at soil level. Divide congested clumps every 3–4 years.

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.
