What these dates mean in Northern Illinois
Planting usually runs about 83 days, from May 15 to Aug 5.
That start date is about 7 days later than the middle of the 4 places in this data set that report turnip planting dates (May 8).
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.
