What these dates mean in Colorado

Planting usually runs about 41 days, from Sep 1 to Oct 11.

That start date is about 16 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 33 days, from Jun 27 to Jul 29.

From the start of the planting window to the start of the harvest window is about 299 days in Colorado, a rough guide to how long the crop occupies the bed or field.

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