Tassel Grape Hyacinth problems — and how to fix them
Tassel Grape Hyacinth (Muscari comosum) 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.
Poor or absent tassels
Insufficient sun is the most common reason the distinctive sterile upper florets fail to form or remain sparse; move bulbs to a sunnier position and ensure they are not shaded by neighbouring plants.
Bulb rot in waterlogged soil
Though tolerant of dry conditions, prolonged winter waterlogging causes the large bulbs to rot at the base plate; improve drainage by adding coarse grit and planting on a slight slope or raised bed.
