When to prune variegated greater periwinkle in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune variegated greater periwinkle
Deadhead spent blooms; cut back leggy stems to a healthy bud or node.
Prune variegated greater periwinkle mainly to shape it and encourage more blooms. Deadhead spent flowers through the season, and carry out any harder structural pruning at the plant's dormant or post-flowering window to avoid cutting off the next round of buds.

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.
