When to prune adromischus maculatus 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 adromischus maculatus
Gently twist or cut dead leaves free at the base. If rot appears on a stem, cut back to clean healthy tissue with a sterile blade and allow the cut to callous before watering.
Adromischus maculatus (calico hearts) is a compact succulent that needs minimal pruning. Remove dead or mushy leaves cleanly from the stem to prevent rot and maintain appearance. No shaping cuts are required — the plant grows slowly and stays naturally tidy. Only prune damaged stems if rot or injury is present.

Prune adromischus maculatus in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

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.
