When to prune caralluma hesperidum 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 caralluma hesperidum
Cut dead or decaying stems cleanly at the base with sterilised scissors. Dry the cut end for 2–3 days before exposing to moisture to reduce infection risk.
Caralluma hesperidum is a low-maintenance succulent requiring minimal pruning. Remove dead, shrivelled, or diseased stems at the base to prevent rot spreading. Very overcrowded clumps can be thinned by detaching a few stems for propagation. Healthy stems need no cutting — shaping is neither necessary nor beneficial for this plant.

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.
