Plant hyacinth bulbs in fall about six to eight weeks before the first expected frost in your area. Hyacinth bulbs thrive in partial shade to full sunlight and plants tolerate nearly any type of well-drained soil, although moderately rich soil is ideal. It’s a good idea to loosen the soil and dig in a generous amount of compost before growing hyacinth bulbs. Water well after planting bulbs, then allow hyacinths to dry out slightly between watering. Be careful not to overwater, as these plants don’t tolerate soggy soil and may rot or mold
