When to prune tagetes erecta 'inca gold' 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 tagetes erecta 'inca gold'
Cut the flower stem back to the first healthy set of leaves beneath the spent bloom. For a full rejuvenation, shear the entire plant back by one-third and water well; new flowering shoots emerge within two to three weeks.
African marigolds like 'Inca Gold' produce large blooms that need regular deadheading to stay productive. Remove spent flowers promptly — they are large and can rot onto foliage if left in place. A mid-season cutback of about one-third revives tired plants. Deadheading is the single most impactful pruning task.

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.
