What these dates mean in Northern Illinois
Planting usually runs about 31 days, from Apr 14 to May 14.
That start date is about 13 days later than the middle of the 8 places in this data set that report endive planting dates (Apr 1).
Frost-date caveat: these are published ranges for Northern 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.
