When to prune rocket candytuft 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 rocket candytuft
Snip spent flower stems back to a healthy sideshoot or leaf node with scissors. Do not cut into bare woody stem — new growth breaks from leafy tissue.
Rocket candytuft is a fast-growing annual grown primarily for cut flowers and fragrance. Deadhead spent stems regularly to extend the blooming period. Once the plant has run to seed in late summer, it is pulled and composted — no winter pruning is needed. A light trim mid-season can push out additional sideshoots.

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.
