Oxford and Cambridge Grape Hyacinth problems — and how to fix them
Oxford and Cambridge Grape Hyacinth (Muscari aucheri) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Overcrowding and blind bulbs
Dense congested clumps produce foliage but fewer flowers over time; lift and divide every 3–4 years in summer when dormant to maintain vigour and flowering.
Self-seeding invasiveness
Muscari aucheri can self-seed prolifically and spread into areas where it is not wanted; deadhead spent flower spikes before seed sets if naturalising in a controlled bed.
