When to prune blue mouse ears hosta 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.

Blue Mouse Ears hosta is a compact, slow-growing miniature variety that needs almost no pruning. Simply remove individual leaves as they yellow or die back through the season, and cut the whole plant to the ground in autumn after frost kills the foliage. Flower scapes can be removed after blooming if desired.

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.
