When to prune viola 'sorbet raspberry' 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 viola 'sorbet raspberry'
Snip off spent blooms just below the flower. For a shape reset, cut stems back by one-third above a healthy leaf node using clean scissors.
Viola 'Sorbet Raspberry' is a cool-season pansy that benefits greatly from regular deadheading to prolong blooming. Remove spent flowers before seeds set. Cut plants back by one-third in mid-spring if they become leggy. These are short-season annuals — no pruning will prevent summer decline, so replace plants in summer heat.

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.
