What these dates mean in Ohio

Planting usually runs about 40 days, from Apr 4 to May 13.

That start date is about 4 days later than the middle of the 24 places in this data set that report spring oats planting dates (Mar 31).

Harvest usually runs about 30 days, from Jul 13 to Aug 11.

From the start of the planting window to the start of the harvest window is about 100 days in Ohio, a rough guide to how long the crop occupies the bed or field.

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