When to prune hoya australis in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune hoya australis
Cut leggy vines back to a healthy leaf node with sterilized scissors. Preserve all short, woody flowering spurs. Remove dead stems at their base.
Hoya australis requires minimal pruning. As with all hoyas, the key rule is to never cut the peduncles (flower spurs), which rebloom repeatedly. Trim back excessively long vines to a leaf node to manage size, and remove any dead or yellowed stems. Otherwise, leave the plant to grow freely.

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.
