When to prune paeonia mlokosewitschii 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 paeonia mlokosewitschii
In autumn, cut all stems to 2–3 inches above soil level with clean secateurs and clear all debris. If deadheading, cut just below the spent bloom in early summer. Otherwise let the attractive seed pods develop and remove stems in autumn.
Paeonia mlokosewitschii (Molly the Witch) is a species peony with attractive seed pods after the brief spring bloom. Cut stems back to ground level in autumn after foliage yellows. If you want the ornamental red-seeded pods, skip deadheading and let seed heads mature naturally. No summer pruning is needed.

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.
