When to prune double-flowered chamomile 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 double-flowered chamomile
Pinch or cut spent blooms at the stem; after the main flush, use garden shears to cut the whole mat back by one-third, cutting above the lowest leafy growth.
Double-flowered Chamomile ('Flore Pleno') is a non-seeding ornamental grown for its pompom blooms. Deadhead regularly to prolong flowering through summer. After the main flush, shear the plant back by about a third to encourage a second flush. Trim in spring to remove winter-damaged growth and refresh the mat.

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.
