This vigorous oak leave heirloom variety has bright burgundy red leaves that are deeply lobed, creating a full rosette with a typical green center. Great for baby leaf salad mixes. Red Oak Leaf is slow to bolt, tender, and mild-tasting. However, once it has bolted (starts to produce a rapidly growing flower stem) the leaves will become bitter. It is best grown in early spring or late summer and early fall as the cool nights are beneficial for a better harvest.
Some lettuce seed types are especially light sensitive and require light to germinate; hence they must be sown just barely below soil surface in full sun. Direct sow lettuce seeds or start indoors and transplant when the risk of frost has passed. Work soil loose and sow lettuce seeds 2-3 seeds at 5mm-12mm (¼-½") deep and barely cover with soil medium. Lettuce seeds will not germinate when soil temperatures exceed 30°C, (87°F) and do best when soil temperatures remain between 15 to 20°C, 59 to 68° F. Thin to space seedlings to 30cm (12") apart. Space or thin loose leaf varieties to 15cm (6”) apart. Row spacing for all lettuce types should between 30-45cm (12-18”) apart. Lettuce can also be sown in blocks or squares as opposed to rows. Harvest leaf lettuce by either pulling the entire plant or by cutting leaves from the main stem at least 2.5 cm (1") above the base - this will allow the plant to sprout new leaves.
