When to prune wide-leaved grape hyacinth 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 wide-leaved grape hyacinth
Snip off spent flower spikes at the base after bloom. Leave all foliage to wither fully on its own. Tidy dead leaves once they are fully brown and papery.
Wide-leaved Grape Hyacinth needs very little pruning. Remove faded flower spikes to prevent excessive self-seeding if desired. Allow the distinctive broad foliage to die back completely and naturally — do not cut or tie leaves while green. This bulb is naturally compact and requires no shaping or hard pruning.

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.
