UK pruning guide · RHS timing
When to prune tasteless stonecrop 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 tasteless stonecrop
Pinch or snip individual dead stems back to healthy growth at the base. To rejuvenate a bare-centred mat, lift and replant fresh outer rosettes into fresh gritty compost.
Tasteless Stonecrop (Sedum sexangulare) is a tiny, mat-forming succulent that rarely needs pruning indoors. It naturally stays compact. Remove any dead or yellowing stems as you notice them. If the mat grows beyond its container or becomes bare in the centre, trim back spreading stems lightly or divide the clump.

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.
