When to prune zinnia elegans 'benary's giant coral' 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 'benary's giant coral'
Cut spent blooms back to a lateral shoot or leaf node rather than just removing the flower head. This encourages side-branching and more flower stems.
Zinnia 'Benary's Giant Coral' blooms longer with regular deadheading. Remove spent flowers by cutting back to a side shoot or pair of leaves to encourage branching and new buds. Pinching young transplants once at planting promotes bushier plants, though this variety's vigour means it branches well on its own.

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.
