I think that this is what you should try
Particularly desirable Hyacinth cultivars can be propagated by making a
number of cuts in the bulb, which promotes the development of new bulblets.
Turn the Hyacinth bulb upside down, and cut away the basal plate of the bulb
using a sharp knife. Then make a series of V-shaped cuts around the edge of
the bulb where the basal plate was removed. Leave the bulb exposed to the
air for a few days to allow it to form a protective callus. Finally bury he
bulb upside down in moist, sand and new bulblets will grow from the wounds
made in the base of the Hyacinth bulb.
