Lettuce - Green Oakleaf
Lactuca sativaHEIRLOOM -Rightfully famous for over 242 years! Bright green, deeply lobed leaves are never bitter, even in the summertime heat. Before modern lettuce ended up in salad bowls everywhere, it had a place as an aphrodisiac in pre-dynastic Egyptian ceremonies, cooked with eggs on the Roman dinner table, and in medieval herbals as a sedative and digestive. Now, it comes in a beautiful variety of forms, colors, and textures from smooth lime green leaves to red headings, to multicolored, smooth or crinkled leaves, with flavors ranging from a bracing bitterness to a soft buttery taste. While all lettuces can be harvested for loose leaf salad mix, romaine and butterhead varieties create folded heads for single head harvest. Nutrients: vitamins K (high), A and folate.

Lettuce is a very easy-to-grow lightly frost-tolerant annual that grows best in full sun, but will tolerate part shade. Pick a spot that receives at least 5 hours of sun a day. Lettuce greens grow most successfully in well-drained soil that is both rich in nutrients and moist.
Most lettuce germinates poorly in hot weather and bolts quickly, so be sure to plant in early spring, late summer or early fall. Succession plantings every two to three weeks are recommended for a continual harvest through the fall. Plant Seeds: 1/8"deep with 1/2" between seeds and 12" between rows. Plant several seeds in each hole. Thoroughly water seeds after planting. Continually water lettuce daily to keep soil moist. As seedlings emerge, thin them 6-10” apart for mature heads or do not thin for baby leaves. Seeds will sprout in 3-15 days.
Baby lettuce leaves are ready to harvest in about 24 days. Days to maturity for heads will vary depending on the variety. Harvest above growth point for cut-and-come-again production or cut lettuce at soil line with a knife for single harvest.
