There is no way I can tell you that the Creole will grow for you. I am in NE Mississippi, and I am not knowledgeable enough to know whether you would have success growing them up north. I would guess not - eat them! There is not a single thing with hardneck garlic. They just won't store as long. Creole garlics are in a class by themselves, so there is no use in comparing them with anything else.
When I dig my garlic up, I simply shake off all the dirt I can from the roots and bulbs before hanging them up to cure. That's it. When the bulbs have cured for two or so weeks, I will the remove the remaining soil with my fingers before cutting off the stems and then weighing them to bag. I never put water on them.
Thanks for the info about processing the garlic for drying.
