When to prune corsican mint in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune corsican mint
Use fine scissors or fingertips to remove dead patches. Trim mat edges with scissors if it is spreading beyond its allotted space. Avoid cutting into completely bare stem as this tiny-leafed species recovers slowly.
Corsican Mint is a low, mat-forming ground-cover that rarely needs pruning. It grows only 1–3 cm tall and spreads naturally. Simply remove any dead or brown patches after winter or following dry spells. Light trimming of the edges keeps mats tidy but the plant does not require shaping or hard pruning.

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.
