I like growing my own because so much store garlic comes from China and is grown in who knows what kind of polluted environment.
This year I have a 16’ x 4’ raised bed dedicated just to garlic.
I need to look at my cloves downstairs and if they are starting to deteriorate, need to process them.
Rumor has it you are not supposed to freeze garlic, but I found a half ping canning jar of diced garlic in the freezer when I defrosted it and opened it up and it about burned my eyes out.
Wow, was it strong.

Garlic: Store, Preserve
WE have consumed all ours from last year. When it gets near the end, I make roasted garlic heads and squeeze the contents into a small plastic container. It will keep in the fridge for weeks, although it never lasts that long.
