When to prune pinguicula agnata 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 pinguicula agnata
Use clean, fine-tipped scissors or tweezers to pull or snip dead leaves flush with the base. Cut flower stalks at soil level once fully spent.
Pinguicula agnata needs minimal pruning. Remove dead or blackened leaves at the base as they appear, and snip spent flower stalks once blooms finish. Avoid cutting healthy leaves — the rosette shape is self-regulating. This butterwort does not benefit from shaping or hard cutting back.

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.
