What these dates mean in New Mexico

Planting usually runs about 36 days, from Apr 15 to May 20.

That start date is close to the middle of the 41 places in this data set that report corn planting dates (Apr 14).

Harvest usually runs about 57 days, from Sep 25 to Nov 20.

From the start of the planting window to the start of the harvest window is about 163 days in New Mexico, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for New Mexico. 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.
