When to prune gibbaeum petrense 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 gibbaeum petrense
Hand-remove fully dry, dead leaf remnants if they are causing moisture retention. Do not use scissors on the main plant body and never remove leaves that still have firmness.
Gibbaeum petrense is a dwarf mesemb that requires virtually no pruning. Old leaf pairs shrivel and are replaced by new growth naturally. Only intervene if spent leaf sheaths are clearly trapping moisture at the stem base. Otherwise, leave the plant to manage itself.

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.
