When to prune adromischus trigynus 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 trigynus
Gently pull dead leaves free at the base or cut cleanly with sterile scissors. For any rot, cut back to healthy tissue and allow the wound to callous before watering again.
Adromischus trigynus (calico hearts) needs minimal pruning. Remove dead, mushy, or shriveled leaves from the stem base to keep the plant healthy. This compact, slow-growing succulent maintains its natural form without any shaping cuts. Only remove stem sections if rot or physical damage is present.

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.
