Why
On the calendar: planting on schedule in Minneapolis, MN puts first harvest around May 17 – Jul 3 (our estimate from the typical planting window plus 40-80 days to maturity). Weather, variety and care shift this by weeks — trust the sign above over the date.
Storage: refrigerate; sturdier than lettuce.
- Days-to-maturity figures are averages from trial conditions — your season, variety and weather move them, which is why the visual readiness sign is the deciding test.
When this doesn't apply
- If you planted earlier or later than the typical window, shift the estimated dates by the same amount.
