When to prune primrose huernia 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 primrose huernia
Use clean, sharp scissors or a blade to cut dead or rotted stems at their base. Dust cut surfaces with powdered sulfur or let them callous for a day before watering resumes.
Primrose Huernia is a succulent stapeliad that rarely needs pruning. Remove dead or shriveled stems at the base with clean scissors, and trim any rotting segments promptly to prevent spread. Beyond that, leave it alone — cutting healthy stems reduces the clumping habit and removes next season's flower sites.

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.
