When to prune tagetes patula 'boy 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 patula 'boy orange'
Snap or snip spent flower heads at the base of the bloom stem just above the next leaf node. For leggy plants, cut stems back by up to one-third to a healthy leaf pair to encourage bushy regrowth.
French marigolds like 'Boy Orange' benefit strongly from deadheading — removing spent blooms prevents seed set and keeps flowers coming all season. Pinch back leggy stems by a third in midsummer if the plant gets straggly. Without deadheading, flowering slows noticeably as the plant puts energy into seed production.

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.
