Hi. I have a Hyacinthoide of some kind that was planted long ago at my house built in 1952. It blooms little white bell shaped blossoms every season in the shade of the front shrubbery. I am demolishing the house to build a new one which will sit on top of where the flowers are now. We are just now beginning the process of getting a builder. I would say we would begin in the next couple months. I have heard it is best to dig up and move bulbs in the fall, but I can't do that. I believe the foliage will die back by summer. I have marked the location of the flowers. Would it be better to dig them up now, or wait until right before the demo? I love the cheerful little bells so much! I want to save them if at all possible. Thx
