When to prune moroccan 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 moroccan mint
Cut stems back by one-third to one-half just above a leaf node using clean scissors. Pinch out any flower spikes immediately — flowering redirects energy away from leaf production and weakens flavour.
Moroccan Mint needs regular pruning to stay bushy, prevent flowering, and maintain the best flavour. Left unpruned it bolts and becomes woody. Cut stems back by one-third to one-half whenever they reach 15–20 cm, and remove flower spikes as soon as they appear to keep the foliage harvest-ready all season.

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.
