When to prune burdock 'takinogawa' in the UK
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 burdock 'takinogawa'
Cut damaged outer leaves at their base with clean scissors. To prevent premature seed set in year two, cut the central flower stalk to the base as soon as it begins to elongate. Roots are harvested by digging deeply — typically 60–90 cm — in autumn of year one.
Burdock 'Takinogawa' is grown for its very long taproot and treated as an annual or biennial. Pruning is not a meaningful practice for this crop. Remove any damaged or diseased leaves to improve airflow. If grown as a biennial, cut flowering stalks in year two to delay seed set, though this is harvest management rather than pruning.

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.
