When to prune hoya carnosa tricolor 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 carnosa tricolor
Cut only dead or unhealthy stems back to a node. Preserve every peduncle. For length control, trim vines back to a node without removing the main woody stems. Use clean, sterilised scissors.
Hoya carnosa 'Tricolor' requires minimal pruning. Like all hoyas, never cut the short woody peduncles (flower spurs) — they rebloom season after season. Prune only to remove dead or damaged growth, or to tidy excessively long vines. Reverting stems (losing pink/cream) can be trimmed to keep variegation vivid.

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.
