When to prune podophylla rodgersia 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 podophylla rodgersia
Cut spent flower stems to their base. In autumn or early spring, shear all top growth to just above soil level. Clumps can be divided every 4–5 years in early spring if spreading too wide.
Rodgersia podophylla is a vigorous, largely self-sufficient perennial. The palmate foliage is ornamental from spring through autumn — remove only damaged or diseased leaves during the growing season. Deadhead spent flower panicles at the base after blooming. Cut the whole clump to ground level 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.
