When to prune ginger 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 ginger mint
Shear or cut all stems back to 2–3 inches from the ground as soon as flower buds form. This forces a flush of fresh leafy growth. At the end of the season, cut back fully to ground level. Divide congested plants in spring to rejuvenate and control spread.
Ginger Mint (Mentha × gracilis) is an aromatic, spreading hybrid mint. Like all mints, it needs regular cutting back to prevent flowering and to keep leaves flavorful and fresh. Cut stems hard to the ground two or three times through the season. Contain spread by planting in pots or using a root barrier.

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.
