What these dates mean in Montana

Planting usually runs about 43 days, from Apr 6 to May 18.

That start date is about 8 days later than the middle of the 10 places in this data set that report spring wheat planting dates (Mar 29).

Harvest usually runs about 46 days, from Jul 30 to Sep 13.

From the start of the planting window to the start of the harvest window is about 115 days in Montana, a rough guide to how long the crop occupies the bed or field.

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