What these dates mean in Maine

Planting usually runs about 34 days, from May 4 to Jun 6.

That start date is about 33 days later than the middle of the 17 places in this data set that report spring barley planting dates (Apr 1).

Harvest usually runs about 53 days, from Aug 9 to Sep 30.

From the start of the planting window to the start of the harvest window is about 97 days in Maine, a rough guide to how long the crop occupies the bed or field.

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