I always give my grandmother some garlic from my harvest. She always keeps it in the fridge. I didn't think you were supposed to store garlic in the fridge, so I kept mine in the shop (aka garage). Every spring, her garlic was still good, while mine was dried out. Last year, I wised up and kept my garlic in the fridge. Guess what? This year, I still have some garlic that is good.
Lesson to be learned: listen to your grandmother.
