I've started growing garlic each year, with the idea being I'd store most of it for seed the next year to gradually increase the amount I was growing.
Last year, I planted 100 cloves, and saved about 80 head of garlic in July when I harvested. I hung them in a shady, warm location for a week, and then put them in a bowl and forgot about them till October.
The skin of the cloves was still in pristine condition, but the actual clove has shrunk - I think it had dehydrated. I managed to salvage enough cloves to plant 100 again, but I'd like to avoid this set back again "Growing Great Garlic" but the author didn't really address the storage of garlic for seed.
Searching the internet hasn't really clarified the issue. Some people claim that you should store it in the fridge at a specific temperature and then state it will sprout at that same temp. The University of Georgia says commercially, garlic is stored at 0 Celsius and that home refrigerators are too warm. I've heard people say to store it in a damp terracotta bowl with a lid, but that seems to be a recipe for mold.
How do other people store their garlic?
On a side note, I let my garlic produce scapes, and I harvestedthe bulbils. They dried out fine and had no issue with dehydration, and I'm currently growing them to adjust the garlic to my micro climate..
