When to prune treneague chamomile in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune treneague chamomile
Shear the mat to a uniform height of 3–5 cm using garden shears or a mower on its highest setting. Edge around the perimeter to stop lateral spread into paths or borders.
Treneague Chamomile is a non-flowering, creeping groundcover — it needs virtually no pruning. Trim or shear lightly after the growing season to keep the mat tidy and encourage dense, low growth. Remove any dead patches in spring. It spreads by runners, so edge-trim to contain spread rather than cutting individual stems.

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.
