When to prune wheat cockscomb in the UK
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 wheat cockscomb
Snip spent spikes just above a side shoot or leaf axil to prompt branching and further flower production. Pull or cut damaged leaves cleanly at the stem.
Wheat cockscomb is a slim, upright annual with narrow flower spikes that requires very little pruning. Deadhead spent spikes to encourage further flowering on branching stems. Remove any damaged or diseased foliage as noticed. It does not respond well to hard cutting back, so keep any trimming light.

Pruning itself is not illegal, but destroying an active nest is.

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.
