What these dates mean in Central Illinois
Planting usually runs about 51 days, from Mar 12 to May 1.
That start date is about 20 days earlier than the middle of the 8 places in this data set that report peas planting dates (Apr 1).
Frost-date caveat: these are published ranges for Central Illinois. 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. Planting dates are a general guide; frost dates and local conditions vary. Check your last spring frost and soil temperature, and confirm with your county extension office.
