When to prune geranium × oxonianum 'wargrave pink' 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.

Shear back to 10–15 cm above ground after the main flowering. New foliage and a second flush of bloom follow within weeks. Cut to ground level in autumn, or leave until spring for mild frost protection.
Geranium × oxonianum 'Wargrave Pink' is a free-flowering, spreading cranesbill. Shear the whole plant back by half to two-thirds after the main flush in early summer to refresh the mound and promote a second flush. Cut to ground level in autumn. Divide every 3–4 years as the clump expands vigorously.

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.
