When to prune palm sedge in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune palm sedge
Use garden shears or hedge trimmers to cut the entire clump down to about 5–8 cm above soil level in late winter. This removes dead material and makes way for fresh new stems. Divide congested clumps every 3–5 years.
Palm sedge (Carex muskingumensis) is an upright deciduous-to-semi-evergreen sedge. Cut the whole clump back to about 5–8 cm in late winter or early spring before new growth emerges — it tolerates this better than most evergreen Carex. Remove dead stems through the season as needed.

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.
