When to prune pelargonium 'chocolate mint' in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune pelargonium 'chocolate mint'
Pinch or cut soft stem tips just above a leaf node with clean scissors. After the main flush of flowers, shorten longer stems by one-third to encourage fresh, aromatic foliage and a compact habit.
Pelargonium 'Chocolate Mint' is a scented-leaf trailing herb that benefits from tip-pinching in spring to stay bushy rather than straggly. Trim stems back by one-third after flowering. Remove dead or damaged leaves as they appear. Without pruning it becomes open and leggy fairly quickly.

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.
