What these dates mean in Washington

Planting usually runs about 57 days, from Mar 15 to May 10.

That start date is about 14 days earlier than the middle of the 10 places in this data set that report spring wheat planting dates (Mar 29).

Harvest usually runs about 43 days, from Jul 25 to Sep 5.

From the start of the planting window to the start of the harvest window is about 132 days in Washington, a rough guide to how long the crop occupies the bed or field.

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