When to prune gasteria acinacifolia 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 gasteria acinacifolia
Peel dried outer leaves from the base, working gently to avoid tearing adjacent healthy leaves. Separate rooted offsets carefully during repotting.
Gasteria acinacifolia is one of the larger Gasteria species but still needs very little pruning. Remove dead, dried, or sun-scorched outer leaves by peeling them away at the base. Offsets can be removed and potted separately when crowding occurs. No routine cutting or shaping is required.

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.
