Harvest Tips
Begin harvesting 45-60 days after sowing when rosettes reach 4-6 inches in diameter. For whole-plant harvest, cut at soil level in the morning when plants are crisp. For continuous harvest, pick outer leaves starting at 3-4 inches long. Harvest before temperatures consistently exceed 75°F to avoid excessive bitterness and bolting. Plants can be harvested repeatedly if lower leaves are left intact.
