Tell me again, Mary, what variety you planted last fall. I think my garlic do much better when the soil can dry out some. Even with all our rain down here, my soil never stays soggy. I have well-draining soil with lots of organic matter incorporated plus the fact that I am growing in a fairly deep raised garden and large, tall pot. I a perfect environment, I would like my garlic to NOT get any water whatsoever in the last 4 weeks before I dig it. Of course, one can't control Mother Nature. When I get copious amounts of rain during the last 4 weeks, my garlic is undersized.
You can't use this tip with hardneck garlic, but when it comes to softneck and Creole, when you see those stalks begin to fall over, regardless of whether the lower 30-50% of the leaves appear to have browned, it is time to dig up that garlic - immediately.
