When to prune jointed pectinaria 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 jointed pectinaria
Detach dead or rotted stem segments at the natural joint using clean scissors or a blade. Dust the wound with sulfur powder and withhold water for a few days to let it callous.
Jointed Pectinaria (Pectinaria articulata) is a small, jointed stapeliad succulent related to Caralluma. It needs minimal pruning. Remove dead or rotted segments promptly at the joint to prevent spread. Healthy segments carry flowers and should not be cut. This is a rarely grown specialist plant — handle with care.

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.
