What these dates mean in Minnesota

Planting usually runs about 38 days, from Apr 22 to May 29.

That start date is about 8 days later than the middle of the 41 places in this data set that report corn planting dates (Apr 14).

Harvest usually runs about 58 days, from Sep 27 to Nov 23.

From the start of the planting window to the start of the harvest window is about 158 days in Minnesota, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Minnesota. 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.
