When to prune ice dance 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 ice dance sedge
Use shears or a lawnmower set high to cut the whole clump back to 2–3 inches above soil level once a year. Remove clippings to prevent thatch build-up. Divide congested mats every 4–5 years.
Ice Dance Sedge (Carex morrowii 'Ice Dance') is an evergreen, shade-tolerant ground-cover sedge. It is low-maintenance: in late winter or early spring, shear or mow the clump back to 2–3 inches above the ground to remove tired foliage and encourage a flush of fresh growth. Skip this if the foliage looks clean coming out of winter.

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.
