When to prune zinnia elegans 'profusion cherry' 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 zinnia elegans 'profusion cherry'
Snap or snip spent blooms at their base. For a mid-season refresh, cut the whole plant back by one-third, water well, and apply a balanced liquid feed.
Zinnia 'Profusion Cherry' is one of the most self-cleaning zinnia series and often blooms well without deadheading. Removing spent flowers does extend the display further, and trimming back by a third mid-season revives tired plants. It is minimal-maintenance compared to large-flowered zinnia cultivars.

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.
