Why the timing differs here

British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.

How to prune 'green zebra' tomato

Remove suckers at the stem-branch joint while small. Maintain 1–2 leaders on a vertical support. Strip lower foliage gradually as the plant grows to keep good airflow at the base.

'Green Zebra' is an indeterminate tomato that responds well to suckering. Pruning to 1–2 leaders keeps the plant manageable, improves airflow, and helps the fruits colour and ripen evenly — important since the green-on-green ripeness cues of this variety can be subtle and good light penetration aids judgment.

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.
