When to prune tulista pumila 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 tulista pumila
Snip dead outer leaves flush at the base with sterile scissors. Cut flower stalks down to the base of the rosette once flowers have faded.
Tulista pumila (formerly Haworthia pumila) needs very little pruning. Remove only outer leaves that have fully dried and turned papery, cutting them cleanly at the base. Trim spent flower stalks after blooming. The rosette is self-forming — no shaping is required, and cutting into healthy leaves will mar its appearance.

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.
