UK pruning guide · RHS timing
When to prune thomsonii wax plant 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 thomsonii wax plant
Cut wayward stems cleanly above a leaf node. Keep all spent flower peduncles — they are perennial bloom sites and must not be removed.
Hoya thomsonii requires very little pruning. Remove yellowing, dead, or damaged growth whenever you spot it. If long trailing vines become unruly, trim them back to a node in spring. Crucially, leave old flower peduncles in place — removing them sacrifices future blooms, as this hoya reblooms from the same spur.

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.
