When to prune calibrachoa 'superbells lemon slice' 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 calibrachoa 'superbells lemon slice'
Use clean scissors or your fingers to pinch trailing stems back by up to one-third of their length, cutting just above a leaf node. No deadheading is required — spent flowers drop on their own.
Calibrachoa 'Superbells Lemon Slice' is self-cleaning and rarely needs deadheading. However, pinching back long or leggy stems by one-third in midsummer refreshes the plant, encourages branching, and prolongs the flush of bloom through autumn. Remove any dead or diseased stems promptly to keep the mound tidy.

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.
