When to prune graceful cattail 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 graceful cattail
Cut old stems to about 15 cm above the waterline or soil surface using loppers or shears; collect and remove all cuttings and spent seed heads from the water to prevent decomposition and spread.
Graceful cattail (Typha laxmannii) is smaller and less aggressive than common cattail but still benefits from annual cutting back to maintain shape and limit spread. Cut stems to around 15 cm above the base in late winter or early spring. Remove seed heads before they disperse to control self-seeding in the surrounding water garden.

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.
