When to prune larryleachia marlothii in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune larryleachia marlothii
Use sterilised scissors or a clean blade to cut away dead or rotting stems at the base. Allow cut surfaces to callous before watering. No shaping is required or beneficial.
Larryleachia marlothii (formerly Trichocaulon marlothii) is a small, slow-growing succulent with spiny tuberculate stems. It needs no regular pruning. Simply remove dead or rotting stems cleanly at the base. Healthy stems should never be cut back — the plant's structure is naturally contained and cutting invites fungal rot.

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.
