Adaptive Seeds Summer Lettuce Mix (Organic)
Lactuca sativa. 28 days.
Features varieties that have performed well in our hot weather lettuce trials. Includes crisphead, romaine, oak leaf, and butterhead varieties, making this mix work well for head lettuce or cut-and-come-again salad mix production. We recommend this mix for summer sowings in the Pacific Northwest.
Sow indoors in flats with good potting soil year-round. Transplant into the garden at 1′ spacing 3-4 weeks after sprouting. Alternatively, direct sow March through September. In our area, lettuce can go through winter if protected. Succession sow for continual harvest.
Collect seeds when flowers are downy like dandelions. Cut seed heads and place upside down in a bag to dry for a few days. Knock seed heads against side of bucket or tote, rub downy fluff off seeds. Winnow and screen to clean.
