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 goji berry

Year 1–2: select a single leader and remove competing stems. Established plants: shorten laterals by up to one-third to encourage fruiting spur development; remove any dead, diseased, or crossing stems entirely. Tip-prune after summer harvest to stimulate new growth for next season.

Goji Berry fruits on new growth produced from two-year-old wood and benefits from structured annual pruning. In the first two years, train a short main trunk (30–60 cm) with four to six main lateral branches. On established plants, shorten laterals and remove the weakest stems to encourage strong fruiting spurs and prevent the arching canes from becoming an impenetrable thicket.

Pruning goji berry in the UK — FAQ

When should I prune goji berry in the UK?

Prune goji berry in early to mid spring.

Is it illegal to prune goji berry in spring or summer in the UK?

Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check goji berry for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
