When to prune graptosedum '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 graptosedum 'california sunset'
Cut leggy stems close to the soil with clean clippers, keeping the cut area dry. The removed rosette head can be propagated as a cutting.
Graptosedum 'California Sunset' needs little pruning. Remove damaged or yellowing leaves to keep the plant tidy. If it becomes leggy — common in low light — prune off a rosette to propagate it; the bare stem will sprout new rosettes. More sun prevents legginess far better than pruning alone.

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.
