When to prune gattefosse's 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 gattefosse's mint
Pinch or snip stems just above a pair of leaves to encourage branching.
Gattefosse's Mint responds well to regular light pruning. Pinching back the growing tips every couple of weeks keeps the plant bushy, delays flowering (which can turn the leaves bitter), and gives you a steady harvest. Always cut just above a leaf node.

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.
