When to prune pearl plant 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 pearl plant
Peel or snap off completely dried outer leaves at the base with clean fingers or tweezers. Do not cut green leaves — the rosette form is natural and requires no shaping.
Pearl Plant (Haworthiopsis fasciata) needs virtually no pruning. It grows in tight rosettes and does not branch or sprawl. Simply remove any brown, dried, or damaged outer leaves by peeling them away cleanly at the base. No shaping or cutting is required or beneficial.

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.
