When to plant garlic in the United States: 24 Aug – end of December

Garlic in the United States: plant from 24 August to the end of December; the window opens earliest in Fairbanks and closes latest in New York (133 cities).

From a month before the first autumn frost, so the roots grow before winter, to the late-planting limit on each crop’s page (about two weeks before the ground freezes, by ten years of weather).
