When to prune sarracenia × catesbaei 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 sarracenia × catesbaei
Cut dead pitchers and any brown phyllodia back to the base of the rhizome with clean scissors. Remove debris to prevent mould. Divide congested rhizomes in early spring if the clump becomes overcrowded.
Sarracenia × catesbaei is a vigorous natural hybrid that dies back in winter. Cut all dead pitchers and leaves down to the rhizome in late autumn or early spring before new growth emerges. Avoid trimming healthy pitchers in the growing season — they capture the insects the plant needs. Annual cleanup is all that is 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.
