Planting garlic now in Zone 5b
I didn't get around to planting garlic last fall. I've planted it as late as early December here in zone 5b with good results. Its been so warm here (64 F tomorrow), that the ground is not frozen and I'd be able to plant it some day this week. Will heads form by late summer?
Can anyone explain why its necessary to plant garlic in the fall in cold winter areas in order for it to form heads the following summer?
