When to prune calibrachoa 'minifamous double amethyst' 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 'minifamous double amethyst'
Pinch or cut stems back by one-third above a healthy leaf node using clean scissors. Remove clinging spent double flowers by hand to prevent rot in humid conditions.
Calibrachoa 'MiniFamous Double Amethyst' is largely self-cleaning. Its double flowers do not shed as readily as singles, so occasional removal of spent blooms and a light trim in midsummer keeps it looking neat and prevents stem buildup. Pinching back leggy growth by one-third promotes a denser, more floriferous plant.

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.
