UK pruning guide · RHS timing
When to prune hoya calycina 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 calycina
Trim overly long stems to a healthy node with clean, sharp scissors. Never remove peduncles; Hoya calycina produces impressive blooms repeatedly from the same woody spurs.
Hoya calycina needs very little pruning. Remove dead or damaged stems at any time. If the vine sprawls beyond its allotted space, cut trailing stems back to a healthy node in spring. Leave all peduncles untouched — they carry the plant's large, fragrant flower umbels.

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.
