When to prune tanquana prismatica 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 tanquana prismatica
Gently pull or snip dead outer leaves at the base with clean scissors. Never cut into living leaf tissue.
Tanquana prismatica is a compact South African mesemb succulent that rarely needs pruning. Simply remove any dead, shrivelled, or damaged leaves at the base as needed. Do not cut into healthy fleshy leaves — the plant naturally sheds old outer leaves as new growth emerges from the centre.

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.
