When to prune african marigold 'crackerjack' 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 african marigold 'crackerjack'
Grip the spent flower stem just above the uppermost set of leaves and snap or cut cleanly. Remove any yellowing foliage at the same time to improve air circulation.
African Marigold 'Crackerjack' produces large blooms that should be deadheaded regularly — old heads are heavy and can trap moisture, leading to botrytis. Remove each spent flower back to a leaf node to redirect energy into new buds. Pinch transplants once at planting time to prevent a single-stemmed, lanky habit.

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.
