When to prune geranium x 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.
How to prune geranium x oxonianum 'wargrave pink'
Cut all stems back to 5–10 cm after peak flowering, then water and feed lightly. Repeat-blooming begins within a few weeks. In late autumn, cut remaining stems to ground level or leave for frost insulation and cut back in spring.
Geranium x oxonianum 'Wargrave Pink' produces salmon-pink flowers over a very long season and benefits greatly from a hard midsummer cutback. Shear all stems to near ground level after the first flush to prompt strong regrowth and repeat bloom into autumn. Cut to ground in late autumn or early spring.

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.
