When to prune salvia splendens 'vista red' 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 salvia splendens 'vista red'
Pinch shoot tips to 2 leaf nodes at transplant to encourage branching. When the first wave of flower spikes browns, cut stems back to the nearest healthy lateral bud or leaf pair with clean scissors or shears.
Salvia 'Vista Red' is a self-cleaning, compact cultivar that needs less deadheading than older salvias, but pinching at transplant time and occasional light shearing still improve bushiness and prolonged bloom. Remove spent spike clusters to prevent energy going to seed and maintain the vivid red display through frost.

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.
