When to prune petunia 'supertunia vista bubblegum' 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 petunia 'supertunia vista bubblegum'
Cut all stems back by one-third using scissors or shears. Cut above a leaf node to encourage branching. Follow immediately with a balanced liquid feed. Supertunia varieties recover quickly and typically rebloom within 2–3 weeks.
Petunia 'Supertunia Vista Bubblegum' is a vigorous self-cleaning hybrid that requires less deadheading than older types, as it drops spent flowers on its own. However, a mid-season cutback by about a third prevents legginess and keeps the plant bushy and free-flowering. Feed well after trimming to support regrowth.

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.
