When to prune 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 haworthia
Peel dead outer leaves downward and off at the base cleanly with your fingers or a sterile blade. To remove a pup, unpot the plant, separate the offset where it joins the mother rosette, and allow the cut to callous for a day before potting up.
Haworthia rarely needs pruning. The plant grows as a rosette and does not branch or extend stems that require cutting back. Simply remove dead or shrivelled outer leaves by peeling them away at the base. Offsets (pups) can be detached during repotting if you want to propagate or tidy the clump.

Pruning haworthia in the UK — FAQ
When should I prune haworthia in the UK?
Prune haworthia in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune haworthia in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to haworthia, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.

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.
