Hi my name is Barbara, I have about 200 Butterfly Amaryllis bulbs that did not bloom last year. What can I do to make them bloom again? I really don't know very much about caring for and growing bulb but I would really like to learn. I am in Orange County Ca and have a large garden every year but I have not experience growing bulbs. They have all bloomed in the past but this year nothing. Thank you so much for your help
Barbara
