The pails were stored open in my unheated basement, and right next to a 5 gal pail of apples (which lasted until February). I too suspect that the cloves would have sprouted in a closed container. Hopefully the apples were not responsible for the long life of the garlic, but I'll repeat that arrangement this year- no sense taking chances.
I'm astonished that there appears to be virtually
no drying, even of cloves which lost their skins... the humidity at ground level on the concrete floor must be constant. And because cold air sinks, the temperature must be fairly constant too. Still, even though the basement is unheated, I spend enough time there that I never thought of it as a root cellar.
I've never tried Spring planted garlic... it never lasted that long before. And it is so contrary to conventional wisdom that it would would be like Spring-planted tulips. Up until now, my cloves would begin to sprout around December, so I would dehydrate them before they spoiled. Spring planting should be interesting.
I was also able to over-winter some of the top-set bulbils downstairs, for one of the rocambole varieties. This is really encouraging from a preservation perspective; it means that I can save backups, should something (like bad weather) destroy the Fall planting. And being able to save bulbils over the winter means that I have backups in case disease strikes the Fall planting (as it did in 2013).
BTW, out of curiosity, I tried eating a piece of one of the garlic cloves raw to see how the flavor had fared.









Wow!!! That raw garlic might even be a challenge for pepper heads. I think it sanitized my mouth, before I was forced to spit it out. Can't remember which variety it was, so maybe it sanitized my brain too.
