When to prune globe artichoke 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 globe artichoke
For harvest, cut the central bud first when tight and firm, which stimulates smaller side buds. In autumn, cut all stems to 2–3 inches above the crown and mulch heavily. In spring, remove surplus suckers, keeping the strongest 1–2 shoots per plant.
Globe artichoke needs two types of pruning: harvest flower buds before they open (cut the stem 3–4 inches below the bud), and cut the entire plant back hard to ground level in autumn after the last bud. Remove basal offsets (suckers) in spring, keeping only 1–2 strong shoots per crown.

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.
