When to prune geranium cinereum 'ballerina' 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 geranium cinereum 'ballerina'
Pinch or snip individual spent flower stems back to the basal rosette. Remove dead leaves at the base. If the plant looks untidy after flowering, trim lightly with scissors — avoid removing more than a third of the foliage.
Geranium cinereum 'Ballerina' is a compact alpine cranesbill that needs very little pruning. Deadhead spent flowers through summer to extend bloom, and remove any dead or damaged leaves. A light trim of untidy stems after flowering keeps the low mound tidy, but hard cutting is rarely necessary or beneficial.

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.
