Broad-leaved Grape Hyacinth problems — and how to fix them
Broad-leaved Grape Hyacinth (Muscari latifolium) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bulb offset failure to flower
Small daughter bulbs may take 1-2 years to reach flowering size. Allow clumps to mature undisturbed for the best display.
Leaf yellowing before flowering
May indicate virus infection or nutrient deficiency. Remove affected plants; check for aphid vectors.
Rot in wet soils
Bulbs rot readily if drainage is poor. Always improve heavy soils with grit before planting.
