When to prune huernia hystrix 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 huernia hystrix
Snap or cut individual dead or rotting stems flush with the base using clean, dry scissors or a blade. Allow the cut end to callous for 2–3 days before any soil contact to prevent rot.
Huernia hystrix rarely needs pruning. Remove dead, shrivelled, or rotting stems at the base using clean scissors. If a clump becomes overcrowded you can detach a few stems and pot them separately — this doubles as propagation. Beyond that, leave it alone; cutting healthy stems serves no horticultural purpose.

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.
