When to prune dwarf papyrus 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 dwarf papyrus
Use sharp scissors or shears to cut dead or yellowed stems cleanly at the base of the clump; remove spent flower heads by cutting the entire stalk back to base level.
Dwarf papyrus benefits from regular tidying rather than hard pruning. Remove dead or yellowing stems at the base throughout the growing season to keep the clump looking fresh. Cut spent flower heads back to the stem base once they fade. In frost-free climates or indoors, light trimming can continue year-round; reduce frequency in winter when growth slows.

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.
