Should I plant a Hyacinth bulb that has sprouted prematurely? Found a hyacinth bulb in a box starting to sprout with small root. Should I keep the bulb in the refrigerator for a few week (now late March and already summer temperatures) or put in water or plant it now? Know nothing about hyacinths except knew they could be kept in water (roots). Think I am in zone 9a or b, not sure.
