UK pruning guide · RHS timing
When to prune serpens wax plant 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 serpens wax plant
Use clean scissors to remove dead or damaged stems at a node. Avoid pruning healthy growth — the plant is slow to recover from heavy cutting.
Hoya serpens is a small, slow-growing hoya that rarely needs pruning. Never cut the flower peduncles — they rebloom year after year. Only trim truly dead or damaged stems back to a healthy node. The plant is compact by nature, so no shaping is generally required.

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.
