When to prune cushion aloe haworthia in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune cushion aloe haworthia
Gently pull dead outer leaves downward to detach them from the stem base. Use clean scissors to snip off spent flower stalks flush with the plant.
Haworthia cymbiformis needs minimal attention. Remove dead or browning outer leaves by gently pulling them free from the base to keep the rosette tidy and reduce rot risk. Spent flower stalks can be trimmed at the base after blooming. No shaping is required — the plant forms a naturally neat rosette.

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.
