When to prune haworthia obtusa 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 haworthia obtusa
Peel dried outer leaves downward and away from the stem. Separate offsets during repotting by gently pulling apart with roots intact.
Haworthia obtusa needs virtually no pruning. Its compact rosette stays tidy on its own. Remove any shrivelled or dead outer leaves by peeling them away from the base. Detach offsets if the pot becomes crowded. No cutting, shaping, or seasonal trimming is required for this slow-growing succulent.

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.
