Why
On the calendar: begin harvest 2 years after planting crowns (3 years from seed); season runs about 6-8 weeks, early May to late June in Minnesota. Watch the plants, not the date — the leaf signal is the trigger.
Storage: refrigerate; use within a few days for best texture.
- 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.
