I just take a spade to them making sure to dig out far enough that I don't hack a bulb in two which I have done before. And yes, I do trim back the stalks/leaves to about 6 inches of stalk and I use that to tie them in a bundle and hang them in our shop where it never freezes.How do you dig them up? Do you cut the tops off? I wanted to dig mine up last year but they still had huge tops on them. Most of them came back and split to multiples. Some didn't come back.
