When to prune hoya fungii 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 fungii
Cut vines back to a healthy leaf node using clean, sterilised scissors. Leave all short, leafless peduncles at nodes completely intact. Avoid removing more than one-third of the plant's foliage at one time.
Hoya fungii is a vigorous, large-leafed hoya vine that needs pruning only to manage size or remove damaged growth. As with all hoyas, never cut the peduncles — these bare spur stems will produce flower clusters repeatedly for years. Otherwise, trim long or unruly vines back to a leaf node. Growth can be fast so annual size-control may be helpful.

Pruning hoya fungii in the UK — FAQ
When should I prune hoya fungii in the UK?

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.
