When to prune muscari 'white magic' in the UK
Why the timing differs here
This one bleeds sap heavily if cut in late winter or early spring, so the RHS advises pruning in late summer or early autumn instead — the opposite of the general dormant-season rule most pruning guides give.
How to prune muscari 'white magic'
Cut or snap off the spent flower stalk at its base. Leave stems and leaves to yellow fully before tidying. Do not cut autumn foliage back.
Muscari botryoides 'White Magic' needs very little pruning. Deadhead the spent flower spikes after blooming to reduce self-seeding and keep the planting tidy. Allow all foliage to die back completely and naturally before removing it — this feeds the bulbs for next year. Autumn-emerging leaves should be left alone over winter.

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.
