When to prune pink surprise calendula 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 pink surprise calendula
Pinch or cut spent flower heads back to a leaf or side shoot immediately below the bloom. For a mid-season refresh, cut stems back by one-third to a leaf node to stimulate compact new growth and additional flowers as temperatures cool.
Pink Surprise calendula (Calendula officinalis 'Pink Surprise') is an annual that blooms longest with regular deadheading. Consistently removing spent flowers prevents seed set and promotes further bud production. Mid-season, if plants get leggy, cut back by one-third. Cool-season growers, they decline in summer heat; deadheading helps extend bloom in shoulder seasons.

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.
