Frost likely Frost possible Frost unlikely Frost is possible from November 15 through March 15, and unlikely the rest of the year. The dashed lines are the typical dates: the last frost around February 21 and the first around December 6.

We don't give a garlic date here. The rule we use, from the University of Minnesota Extension, counts from the first killing frost, and it works where a hard freeze comes every year before the ground freezes. Your county's extension office can tell you when to plant garlic in your climate.
