When to prune amazon mist 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 amazon mist sedge
Remove dead or discoloured leaves by pulling or cutting with scissors at the base. A light overall clip — no more than the top third — can neaten the form without stressing the plant.
Amazon Mist Sedge (Carex comans 'Amazon Mist') is a fine-textured, pale greenish-cream evergreen sedge. Maintenance is minimal: tidy away dead or tatty outer leaves in late winter or early spring. A light overall trim can refresh the look. Avoid cutting hard to the ground. Divide when the centre of the clump becomes dead or hollow.

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.
