Head lettuce Planting Dates in Minnesota

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. Recommended outdoor timing; check forecast and soil temperature; frost dates and local conditions vary (last frost mid-to-late May for tender crops). Check your last spring frost and soil temperature, and confirm with your county extension office.
