Growing Instructions

Sow indoors beginning 8-10 weeks before last frost, or direct sow beginning about 4 weeks before last frost. Plants need full sun in spring and fall, part sun during summer. Harvest late spring and summer sowings promptly to beat bolting. Continue sowing until about 2 weeks before first fall frost. Lettuce likes steady (but not excessive) moisture and can become prematurely bitter during dry spells; keep irrigated for best-tasting leaves.
