When to prune empire scarlet star in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune empire scarlet star

Guzmania lingulata 'Empire' flowers once then dies back — pruning does not extend the mother plant's life. After flowering, cut the spent central spike back neatly. Remove the mother rosette at the base once it yellows fully, leaving offsets (pups) to grow on. Routine pruning is not needed.

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.
