When to prune tagetes tenuifolia 'tangerine gem' 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 tenuifolia 'tangerine gem'
Pinch or snip individual spent blooms at their base. For an overall refresh, cut plants back by about one-third with scissors or shears, then water and feed lightly.
Signet marigold 'Tangerine Gem' is largely self-cleaning, but regular deadheading prolongs blooming significantly. Pinch off spent flowers as they fade to prevent seed set and keep new buds coming. A light shear by mid-summer if plants become straggly will encourage a fresh flush of growth and flowers.

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.
