When to prune hoya caudata (sumatra) 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 caudata (sumatra)
Cut dead or leggy stems back to a node with clean scissors. Leave peduncles untouched. Guide long vines onto a trellis to manage spread without cutting.
Hoya caudata needs very little pruning. Preserve all peduncles for repeat flowering. In spring, trim any dead, damaged, or excessively bare stems back to a healthy node. The plant is a moderate climber — train it onto a trellis rather than cutting back. Overall, minimal intervention is best.

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.
