When to prune utricularia livida 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 utricularia livida
Snip spent scapes at soil level. If the mat is overcrowded, gently lift and remove excess growth from the pot edges with scissors.
Utricularia livida is a terrestrial bladderwort that forms a low mat and rarely needs pruning. Remove spent flower stalks once blooms fade to keep the pot tidy. The plant spreads vegetatively and self-regulates; no shaping is required. Thin overcrowded mats only if growth smothers itself or overflows the container.

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.
