Well, it seems that Ken -- who is pretty far south -- and me, in the far north -- and Glenn (somewhere in the middle) are all planting at around the same time; so, assuming you're in the northern hemisphere, Bojohn, I think you can still plant your garlic! In the north you want to plant it early enough that it will start growing roots, but not so early that it sprouts up out of the ground -- because the shoots will die back over the winter and then the clove will be weakened when it has to start all over.
