Harvest Tips
Harvest when heads are firm and compact, typically 60-75 days after transplanting or 75-85 days from seed. Cut heads at the base using a sharp knife. For fall crops, harvest before hard freezes. Michihili stores excellently in cool conditions (32-40°F, 90-95% humidity) for 2-3 months. Early morning harvest yields crisper, sweeter heads.
