When to prune bacopa 'snowtopia' 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 bacopa 'snowtopia'
Shear the whole plant back by one-third with clean scissors or pruning snips, cutting just above a leaf node. Remove any dead or yellowing stems entirely.
Bacopa 'Snowtopia' benefits from regular light trimming to stay bushy and keep blooming. Cut stems back by one-third when flowering slows or plants become leggy. This is a prolific self-cleaner, but a shear mid-season restores compact form and triggers a fresh flush of white flowers within two to three weeks.

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.
