When to prune kirk's 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 kirk's huernia
Cut dead or spent stems at the base with clean, sharp scissors. Let cut surfaces air-dry and callous for 24 hours before the next watering to minimise rot risk.
Kirk's Huernia (Huernia kirkii) needs only minimal maintenance pruning. Remove any shrivelled, dead, or rotting stems promptly to protect the rest of the clump. After flowering, spent stems can be trimmed back. No shaping or structural pruning is required — this succulent forms its characteristic clusters naturally.

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.
