When to prune italian oregano 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 italian oregano
Snip stems back by half just above a leaf pair throughout the growing season. Remove flower buds as soon as they form. In autumn, cut the whole plant back to 5–8 cm above soil level to refresh the base.
Italian Oregano (a hybrid of sweet marjoram and oregano) is vigorous and must be pruned regularly to keep it bushy and flavourful. Cut back by half when stems reach 20 cm, and remove flower spikes promptly — once it flowers fully the leaves become less aromatic. Hard cut-back in autumn prevents excessive woodiness.

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.
