What these dates mean in Southern Illinois
Transplanting usually runs about 32 days, from Mar 15 to Apr 15.
That start date is about 17 days earlier than the middle of the 3 places in this data set that report kale transplanting dates (Apr 1).
Frost-date caveat: these are published ranges for Southern 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.
