When to prune aesculifolia 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 aesculifolia rodgersia
Snip damaged individual leaves at the stem. Cut spent flower stems to their base after blooming. In autumn or spring, cut all growth to just above soil level with shears.
Rodgersia aesculifolia needs minimal pruning. Its large, horse-chestnut-like leaves are the main feature; remove any that are damaged or wind-scorched during the season. Deadhead spent creamy flower plumes at the stem base if desired. Cut all growth to ground level in late autumn or tidy up in early spring before new leaves emerge.

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.
