What these dates mean in Minnesota
Start indoors usually runs about 28 days, from Feb 1 to Feb 28.
Frost-date caveat: these are published ranges for Minnesota. 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. Indoor seed-starting timing; frost dates and local conditions vary. Check your last spring frost and soil temperature, and confirm with your county extension office.
