When to prune geranium macrorrhizum 'spessart' 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 macrorrhizum 'spessart'
Shear the whole clump back by one-third with garden shears once blooms are spent. In spring, remove brown or winter-battered leaves from the base before new growth emerges.
Like the species, Geranium macrorrhizum 'Spessart' is a low-maintenance ground cover with white-flushed pink flowers. Shear the foliage mound back by about a third after the flowers finish in early summer to keep growth compact and fresh. Remove any dead or damaged leaves in early spring. No complex pruning required.

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.
