When to prune california sunset 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 california sunset
Pull dried lower leaves away by hand. If etiolated, cut the stem below the rosette with a clean blade, allow the cut end to callous for a few days, then re-root in gritty compost.
California Sunset is a compact hybrid succulent (Graptopetalum × Sedum) that rarely needs pruning. Remove dead or damaged lower leaves by hand as they dry. If the rosette stretches (etiolates) in low light, behead and re-root the top to restore compactness. Otherwise, leave it alone — routine pruning is unnecessary.

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.
