When do you harvest your garlic? We are in Michigan. Ours is still green and growing.
IN NY and NH, same basic climate zone as Michigan, it’s late July/early Aug.
My garlic is just starting to send up the scapes, the flower stalks. I cut those off and give them away. I lot of people like to use them in cooking.
A few weeks after that, the leaves start turning brown from the bottom up. Each leave is one layer of skin on the garlic, so when about half the leaves have turned brown is when you harvest the garlic.
We cut our scapes off yesterday - more plant energy goes into the bulbs, and they taste great in eggs, (our hens give us plenty of organic eggs).
The garlic usually starts to brown and die back in late June - so that's when we dig them up.
We only plant a couple of dozen, so the largest bulbs are set apart to replant in the fall, the rest get tied up and hung by their stalks in the basement. God is good.
