Indoor Hyacinths should first go through a cold period (under 9 degrees) and should be held in the dark until the bud is clear from the bulb. The growth point on the bulb will then become slightly thinner at the base. The bulb can then be placed directly in the light and warmth. Hyacinths that are prepared mid-September can most likely be planted indoors early December.
