Just keep it watered when conditions are dry. I suspect you will get smaller bulbs. But they will still be usable. I would recommend digging them when the tops die and replanting, so that you get the larger bulbs in the spring of 2015. Garlic is pretty hardy.

October is the "right" time to plant garlic but we have always replanted in July when we dig. I would do it as George says. You probably won't get better or bigger heads if you leave them undisturbed. Dig and choose the largest cloves to replant for next year.

I've never taken the time to learn the art of producing good crops of garlic.
I had planned on just leaving it, but digging and replanting makes sense and will take care of the problem of not being able obtain seed stock at the right time of year. The plan this year was to order some and plant in the fall.
Guess I still have that option, if I want to try some different varieties.
Water won't be a problem. I'll be expanding my automatic watering system to include the front garden, this year.
Any recommendations on mulch? I have pine straw, wood chips and oak leaves onhand.

Pine straw, wood chips and oak leaves are all good mulches for garlic. It's your choice as to which looks best. It might be easier to rake off the pine straw and oak leaves when it comes time to dig.
