When to prune overdam variegated feather reed grass 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 overdam variegated feather reed grass
Cut the entire clump down to 4–6 inches using sharp shears or hedge clippers. Tie the clump with twine first to contain the cut material and make clean-up easier. Do not cut in autumn — the standing stems provide winter structure and wildlife value.
Yes — Overdam Feather Reed Grass benefits from an annual hard cutback. As a cool-season grass it greens up early, so cut the clump to about 4–6 inches in late winter or very early spring before new shoots appear. This removes tatty foliage and lets the fresh white-striped growth emerge cleanly. Beyond that, no pruning is needed during the growing 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.
