When to prune purple stripe garlic 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 purple stripe garlic
Snap or cut the scape cleanly at its base. Leave all green leaves in place to continue feeding the developing bulb.
Purple Stripe garlic produces scapes that should be removed in early summer to maximize bulb size. Snap or cut the scape once it curls but before it straightens fully. Beyond scape removal, no further pruning is required — leave all foliage intact until harvest time when lower leaves begin to brown.

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.
