When to prune hoya pubicalyx 'splash' 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 'splash'
Cut long, leggy vines back to a node using clean, sterile scissors. Preserve all peduncles (short stubby nodes where flower clusters emerge) — removing them delays or prevents reblooming. Remove dead or yellowed leaves at any time. Cuttings root readily in water or perlite.
Hoya pubicalyx 'Splash' is a vigorous viner that benefits from a light tidy in spring. Trim any excessively long stems to encourage branching and a fuller habit. Never cut the peduncles — hoya flowers return to the same spur year after year. Beyond light shaping and removing dead material, minimal pruning is needed.

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.
