When to prune hoya spartioides 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 hoya spartioides
Use sterilised scissors to remove only clearly dead or damaged stems. Avoid cutting into healthy, green growth — this species' unusual form is part of its appeal and regrowth is slow.
Hoya spartioides has an unusual stick-like, nearly leafless habit and needs almost no pruning. Remove any dead or damaged stems as they appear. Because it is a niche, slow-growing species, cutting healthy growth is counterproductive. Preserve all flower spurs and interfere with the plant's natural structure as little as possible.

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.
