UK pruning guide · RHS timing
When to prune hoya obovata 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 obovata
Trim leggy stems back to a node using clean scissors. Never remove the short, stubby flowering spurs — leave them intact so they can produce future flower clusters.
Hoya obovata needs very little pruning. Avoid cutting flowering spurs (peduncles) — they rebloom year after year. Prune only to remove dead, damaged, or very leggy stems. If you want to control size, trim a few long vines back to a healthy node, but less is more with this slow grower.

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.
