When to prune forbes' glory of the snow 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 forbes' glory of the snow
Pinch or snip spent flower stalks at the base. Allow the slender foliage to yellow and wither fully before removing. When naturalized in lawn, delay mowing until leaves have died down completely.
Forbes' Glory of the Snow needs barely any pruning. It is a small, early bulb that naturalizes well in grass and borders. Deadhead spent flowers to limit spread if desired, or leave seed heads for naturalization. Foliage must die back on its own — typically within 4–6 weeks after bloom.

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.
