When to prune summer savory 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 summer savory
Pinch or snip growing tips just above a leaf pair every 2–3 weeks to encourage branching. Deadhead flower spikes promptly if you want to extend the leafy harvest. Harvest entire stems from the upper third of the plant.
Summer savory is an annual herb that benefits from regular pinching to stay bushy and delay flowering. Harvest frequently by snipping stem tips, which is effectively pruning. Once plants flower, leaf flavour softens — deadhead promptly or accept the decline. As an annual, there is no overwintering pruning cycle; plants are composted at season's end.

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.
