Growing Information:

Lettuce

CULTURE: Lettuce is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and makes its best growth at temperatures of 60-65°F (16-18°C). Careful variety selection is important for hot weather crops. Sow every 3 weeks for a continuous supply of fresh lettuce.
THERMAL DORMANCY: Lettuce can be dormant at high temperatures. For best germination results sow at soil temperatures of 68°F (20°C) or lower. The priming process in pelleted lettuce seeds broadens the temperature range in which the seeds will germinate, overcoming some of their thermal dormancy.
TRANSPLANTING: Sow in flats, 4 seeds/in., or in 3/4" plug trays, barely covering seeds with fine vermiculite, 3-4 weeks before transplanting outdoors. Shade the flats on sunny, warm days if necessary to keep the soil surface cool, below 75°F (24°C), until germination. If sowing into flats, transplant 1-2" apart into flats, pots, or cell-type containers about 2 weeks later. Harden seedlings by reducing water and temperature for 2-3 days before planting outdoors. Properly hardened transplants can survive temperatures as low as 20°F (-6°C). Transplant iceberg lettuce 12" apart in rows 18" apart, other types 8-12" x 12-18" apart.
DIRECT SEEDING: Seeds germinate even at low, 40°F (4°C), soil temperature, but poorly above 75-85°F (24-29°C) depending on the variety and seed lot. Sow seeds 1" apart, rows 12-18" apart. Cover seed lightly, about 1/8", and firm soil gently. Dry soil must be watered to ensure coolness and moisture, and for even germination.
FULL-SIZED HEADS: Begin sowing in spring as soon as the soil is ready, 3 seeds every 8", rows 12-18" apart. Thin young seedlings to one plant every 8".
SALAD MIX/BABY LEAF: Sow in a 2-4" wide band, about 60 seeds/ft.
MT0 SEEDS: A variety name followed by MT0-10 indicates that the seeds offered for sale have been tested for the presence of lettuce mosaic virus and that no LMV was found in a sample of at least 10,000 seeds. MT0-30 indicates that no LMV was found in a sample of at least 30,000 seeds.
NOTE: A disease-free test result does not guarantee a seed lot to be disease-free, only that in the sample tested, the pathogen targeted was not found.
DAYS TO MATURITY: For full-size heads in mild temperatures, from direct seeding; subtract 10-14 days if transplanting. Note: Maturity can be 3 or more weeks later in cool weather, and up to 1 week earlier in hot weather.
AVG. DIRECT SEEDING RATE: For full-size heads (precision seeded): 220'/1,000 seeds, 5,300'/oz., 7.25 oz./acre 2" apart in rows 18" apart. For salad mix: 16'/1,000 seeds, 400'/oz., 6,400'/lb. at 60 seeds/ft.
TRANSPLANTS: Avg. 20,000 plants/oz.
SEED SPECS: SEEDS/OZ.: 20,000-30,000 (avg. 24,000).
PACKET: 500 seeds.
