When to prune navelwort 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 navelwort
Cut spent flower stems down to the basal rosette with clean scissors. Remove individual dead or shrivelled leaves by pulling gently from the base.
Navelwort needs minimal pruning. As a succulent-leaved perennial, remove spent flower spikes after blooming and cut away any yellowed or damaged leaves at the base. In mild climates it may die back seasonally — trim dead stems to the crown. No shaping 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.
