When to prune hoya pubicalyx 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 pubicalyx
Remove dead or diseased sections by cutting back to a healthy node. For length control, shorten vines to a convenient node — each cut end may branch. Leave all peduncles (old flower stalks) intact.
Hoya pubicalyx needs very little pruning. Never remove the woody spurs (peduncles) — flowers return on the same spurs year after year. Trim only truly dead or damaged vines. You can shorten overly long stems if space is limited, cutting just above a node, but the plant blooms best when left to trail or climb freely.

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.
