Ask-a-Dave's-Gardener: Forgotten garlic, 2 by majaz

I just discovered that I had a whole bed of garlic that I forgot to harvest this summer. Unfortunately, they have sprouted and have about 8 inches of new green growth coming up around the original stalk. I’m in zone 4B and we’re having a late Indian summer after a very wet summer. I’m wondering if I could dig up and separate the cloves even though they’ve sprouted and re-plant them. Obviously this might be traumatic to the actively growing garlic, but I might be able to get some usable garlic next year.
