When to prune tagetes erecta 'taishan orange' 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 'taishan orange'
Remove each spent bloom by cutting the stem back to a healthy leaf node. Mid-season, trim the whole plant back by up to one-third if it is becoming leggy or top-heavy.
'Taishan Orange' is a vigorous, tall African marigold that flowers prolifically but slows down if spent blooms are left. Deadhead regularly to maintain continuous colour. The tall stems can become top-heavy; cutting back to a leaf node mid-season keeps the plant from flopping and encourages fresh branching and more blooms.

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.
