What these dates mean in Michigan

Planting usually runs about 50 days, from Sep 13 to Nov 1.

That start date is about 4 days earlier than the middle of the 42 places in this data set that report winter wheat planting dates (Sep 17).

Harvest usually runs about 31 days, from Jul 6 to Aug 5.

From the start of the planting window to the start of the harvest window is about 296 days in Michigan, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Michigan. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual dates from 20-year progress data (Oct 2010 edition), begin ~5% and end ~95% complete. Check your last spring frost and soil temperature, and confirm with your county extension office.
