I was really, really annoyed to have to throw away my remaining garlic crop last week. They'd all started sprouting and gone soft. Last year I managed to keep them fine indoors until the new crop came in, so I'm not sure what I did differently. Yes, I do have some dried and chopped up, but I also like to have some whole cloves so I want to have a string of them hanging up as well. This year I grew an assortment of Iberian Wight and Marco, and most or all of the garlic I had to chuck I believe was Marco.
Would they be better off if I hung them in the garage or shed rather than keeping them indoors? I certainly wouldn't say my garage or shed was frost free, but I doubt if any of them are. But I suspect garlic might be better at handling cold than it is warm. Where does everyone else store theirs?
