When to prune mustard greens 'golden streaks' 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 mustard greens 'golden streaks'
Snip outer fronds with scissors 1–2 inches above soil. Cut flower stalks at the base as soon as they emerge to slow bolting.
'Golden Streaks' is a feathery, mild mustard green suited to cut-and-come-again harvesting. Snip outer fronds regularly to encourage fresh regrowth from the center. Remove flower stalks the moment they appear to prolong the harvest. Its fine texture makes it bolt-prone in heat, so prompt deadheading of bolts is especially important.

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.
