New member here...I've been diggin thru the site to try to find an answer and haven't found what I was looking for. I've grown hyacinths for years in Arizona and was told recently that I don't need to dig up and cool them in the winter to get the tall blooms. In the past when I've left the bulbs in the ground the blooms never fully emerged from the leaves even though the blooms still opened they weren't visible unless you were standing over the plant. My questions being...do they need to have a cool period, how long should it be, if they don't need a chill then how do I get the bloom stalks to grow at least to normal height?
