What these dates mean in Idaho

Planting usually runs about 60 days, from Apr 1 to May 30.

That start date is about 23 days earlier than the middle of the 6 places in this data set that report durum wheat planting dates (Apr 24).

Harvest usually runs about 53 days, from Aug 8 to Sep 29.

From the start of the planting window to the start of the harvest window is about 129 days in Idaho, a rough guide to how long the crop occupies the bed or field.

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