How to Save Seeds

Lettuce is primarily self-pollinating, making it relatively easy to maintain varietal purity. Different lettuce varieties can generally be separated by approximately 50 feet without significant cross-pollination concerns.

Because lettuce is a biennial when grown for seed production, plants must survive through winter before flowering. Allow plants to reach several inches in height before cold weather arrives, then protect them with a thick layer of mulch throughout the winter months.

In spring, the plants will bolt and send up flowering stalks that may reach 4 to 5 feet in height. Once bolting begins, the leaves become bitter and are no longer suitable for eating. Small yellow flowers will continue opening over several weeks as seed production develops.

Watch for mature seeds attached to small feathery tufts. Harvest seeds as they ripen by gently shaking the flowering stalks into a paper bag. Allow seeds to dry completely before storing them in a cool, dry location for future planting.
