When to prune hoya pubicalyx 'red buttons' 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 'red buttons'
Trim long or bare stems just above a leaf node. Pin or train new growth onto a trellis rather than pruning heavily.
Hoya pubicalyx 'Red Buttons' is a vigorous climber that tolerates and benefits from light pruning to manage length and encourage bushier growth. Remove dead or leggy stems. Never cut flower spurs — 'Red Buttons' reliably reblooms on old peduncles, so removing them costs you flowers.

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.
