What these dates mean in Louisiana

Planting usually runs about 35 days, from Mar 13 to Apr 16.

That start date is about 32 days earlier than the middle of the 41 places in this data set that report corn planting dates (Apr 14).

Harvest usually runs about 44 days, from Jul 31 to Sep 12.

From the start of the planting window to the start of the harvest window is about 140 days in Louisiana, a rough guide to how long the crop occupies the bed or field.

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