When to prune gladiolus 'espresso' 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 gladiolus 'espresso'
Snip spent florets as they go over, working up the spike. Cut the finished flower spike to ground level. Keep all green foliage intact to feed the corm through to dormancy.
Gladiolus 'Espresso' needs minimal care — just remove spent florets as they fade along the spike to keep the plant looking its best. Once all flowers on a spike are done, cut it to the base. Foliage must remain until it yellows completely so the corm stores energy for next season.

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.
