When to prune pot marjoram 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 pot marjoram
After flowers fade, cut stems back by one-third to one-half with sharp shears, shaping the plant into a low mound. In spring, remove dead or frost-damaged stems back to the first pair of healthy buds. Avoid cutting into bare woody stems without green foliage.
Pot marjoram benefits from trimming back after each flush of flowers to keep it bushy and prevent it becoming straggly. Cut stems back by up to one-half after flowering. In early spring, trim away any winter-damaged or dead growth before new shoots emerge. More tolerant of hard pruning than common oregano, but always leave green growth on stems.

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.
