When to prune paeonia lactiflora 'festiva maxima' 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 lactiflora 'festiva maxima'
Cut all stems to within 2–3 inches of soil level in autumn using clean, sharp secateurs. Remove deadheads just below the spent flower to the nearest leaf. Clear all debris from the base to reduce botrytis risk.
Herbaceous peonies like 'Festiva Maxima' die back completely each autumn, so the main pruning task is cutting stems to ground level in fall after foliage yellows. Deadhead spent blooms promptly after flowering to keep the plant tidy and prevent disease. No complex shaping is needed — this peony manages itself.

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.
