UK pruning guide · RHS timing
When to prune caralluma speciosa 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 speciosa
Sever dead or affected stems at the base using clean scissors. Let cut surfaces callous and dry for a couple of days before the plant is watered or contacts damp soil.
Caralluma speciosa needs almost no pruning. Remove dead, shrivelled, or rot-affected stems promptly to keep the plant healthy and prevent spread. If the clump becomes very dense, thin a few outer stems to improve airflow. Otherwise, leave established stems alone — they carry the flower buds and do not benefit from cutting back.

When should I prune caralluma speciosa in the UK?
Prune caralluma speciosa in early to mid spring.

If the clump becomes very dense, thin a few outer stems to improve airflow. Otherwise, leave established stems alone — they carry the flower buds and do not benefit from cutting back.
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.
