When to prune hoya clemensiorum in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune hoya clemensiorum
Trim long stems with clean scissors, cutting just above a leaf node. Protect peduncles at all costs. Pull or snip spent or yellowing leaves cleanly at the petiole.
Hoya clemensiorum requires almost no pruning. It produces flowers repeatedly from the same peduncles, so removing them would sacrifice future blooms. Tidy up dead or damaged leaves and stems as needed. If trailing vines become unruly, trim them after flowering. Otherwise, pruning this hoya is unnecessary and risks reducing blooms.

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.
