What these dates mean in Southern Illinois
Planting usually runs about 22 days, from Mar 11 to Apr 1.
That start date is about 68 days earlier than the middle of the 10 places in this data set that report spinach planting dates (May 18).
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.
