UK pruning guide · RHS timing
When to prune hoya praetorii 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 praetorii
Sterilise scissors and cut dead stems back to live wood, or trim long vines just above a node. Peduncles must remain intact for reblooming.
Hoya praetorii is a minimal-pruning houseplant. Only remove stems that are dead, diseased, or clearly damaged. Leave peduncles (flower spurs) completely untouched — they carry repeat blooms. A very light trim to contain the vine can be done in spring. No structured annual pruning routine is necessary.

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.
