What these dates mean in Central Illinois
Transplanting usually runs about 30 days, from Apr 1 to Apr 30.
That start date is close to 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 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.
