When to prune rocambole garlic 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 rocambole garlic
Snap or cut the scape at its base with clean scissors or pinch it off by hand once it has formed one full curl. Do not remove leaves.
Rocambole garlic benefits from one key pruning step: remove the curling flower scape (stem) in early summer before it straightens. This redirects the plant's energy from seed production into bulb development, meaningfully increasing bulb size and flavor. Beyond scape removal, no other pruning is needed during the growing 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.
