When to prune chinese dunce cap 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 chinese dunce cap
Pull away dried outer leaves by hand or snip with clean scissors. Cut the dead flower stalk flush to the base once the rosette has withered completely. Leave offsets to fill in naturally.
Chinese Dunce Cap is a monocarpic rosette succulent — the mother rosette flowers once then dies. Pruning is minimal: remove dead or dying outer leaves and, after the central rosette blooms and withers, cut the spent flower stalk at the base. Offsets that appear around the base can be left or separated.

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.
