UK pruning guide · RHS timing
When to prune hoya sigillatis in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune hoya sigillatis
Remove dead or shrivelled stems back to healthy tissue with clean, sterile scissors. Leave all peduncles untouched. Avoid cutting into healthy green growth unless a stem is clearly dying.
Hoya sigillatis is a slow-growing, pendant Hoya needing very little pruning. Never cut flower spurs — blooms return on the same peduncle. Simply remove any dead or shrivelled stems as they appear. Avoid unnecessary cutting; this species resents disturbance and grows slowly enough that over-pruning sets it back significantly.

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.
