When to prune zebrinus zebra 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 zebrinus zebra grass
Secure the clump with a bungee cord or twine, then cut the entire clump to 4–6 inches above ground. Remove all debris.
Zebrinus Zebra Grass is pruned once a year in late winter before fresh growth begins. Leave the distinctive horizontally-banded clump standing through the cold months for winter interest. Cut the whole clump back to 4–6 inches from the ground using loppers or a hedge trimmer.

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.
