When to prune carex riparia 'variegata' 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 carex riparia 'variegata'
Cut all stems and leaves back to 2–3 inches above the soil or waterline using shears. Remove the clippings from the pond or bog area. Divide clumps every 2–3 years in spring.
Carex riparia 'Variegata' (variegated greater pond sedge) benefits from an annual cutback in late winter to clear dead foliage and reveal the striking white-striped new growth. Like the species, it spreads by rhizomes — dividing congested clumps every few years helps maintain vigour and prevents it crowding out neighbouring plants.

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.
