How to Grow
880 seed/gram. While lettuce is fairly adaptable, it will make its best growth on organic, well-drained soils in sunny locations. Since lettuce is a cool weather crop, sow seed as soon as the soil can be worked in the spring then every two weeks thereafter to ensure a continuous supply. Sow seed about 3 mm (1/8″) deep in rows 45 cm (18″) apart. Lettuce can also be sown in blocks or squares as opposed to rows. Thin heading lettuce to 30 cm (12″) spacing. An even supply of moisture during the entire growth period is imperative for success. Harvest head lettuce by cutting the head off at the base just below the lower leaves. Once lettuce bolts (starts to produce a rapidly growing flower stem) leaves will become bitter.
