When to prune sarracenia leucophylla 'tarnok' 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 leucophylla 'tarnok'
Cut dead pitchers at the base of the rhizome with clean scissors in late autumn. If removing flower stems, cut at the base as soon as they emerge in early spring before energy is spent on blooming.
Sarracenia leucophylla 'Tarnok' produces distinctive double-flowered blooms and tall white-topped pitchers. Remove dead pitchers and foliage in late autumn or early spring. Many growers also remove flower stems as they emerge to direct energy into pitcher production, though the unusual flowers are decorative. Do not cut living pitchers during the growing season.

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.
