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 rot (Fusarium / waterlogging)
Bulbs stored or planted in poorly drained soil are susceptible to fungal rot; ensure sharp drainage and avoid overwatering during dormancy.
Squirrel and rodent damage
Bulbs are frequently dug up by squirrels and mice; plant through wire mesh or use bulb cages to protect them at planting time.
Botrytis (grey mould)
In wet springs, grey mould can affect foliage and flowers; improve air circulation and remove affected material promptly.
