Breen – Organic Lettuce Seed

True compact, red, mini romaine. Organic seed with NOP-compliant pelleting.
Breen forms a very compact mini head early. The short plant averages 8" tall and is very slow to become oversized. Color is a medium bronze red. Though best for mini heads, it can also be used as a medium red baby leaf. Especially nice marketed with other mini romaines. Utility Patent granted. High resistance to downy mildew races EU 16–21, 23–26, 28–33; US 1–9. MT0-30. Organically grown. Avg. 1,100 seeds/oz. Packet: 250 seeds.

SCIENTIFIC NAME: Lactuca sativa
CULTURE: Lettuce is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and grows best at temperatures of 60–65°F (15.5–18.3°C). Careful variety selection is important for hot weather plantings. Sow every 3 weeks for a continuous supply of fresh lettuce. seed requires a little extra attention when it comes to watering, as it performs best with consistent, moderate soil moisture throughout the germination period. An initial watering will split or dissolve the pellet, but if the soil is allowed to dry out before the germination period is over, the seed may receive insufficient moisture for optimal germination.
THERMAL DORMANCY: Lettuce seed can enter thermal dormancy when exposed to high temperatures. Optimum germination results at soil temperatures of 60–68°F (15.5–20°C). 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, 1 seed/in., or in ¾" 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 and romaine lettuce 10–12" apart, in rows 18" apart. Other types 8–10" apart in rows 12–18" apart for full size heads or 6" apart for mini heads.
DIRECT SEEDING: Seeds germinate even at low, 40°F (4°C), soil temperature, but poorly above 75°F (24°C) depending on the variety and seed lot. Sow seeds 2" apart, rows 12–18" apart. Cover seed lightly, about 1/8", and firm soil gently. Thin iceberg and romaine lettuce to one plant every 10–12", other types 8–10" for full size heads or 6" for mini heads. Dry soil must be watered to ensure coolness and moisture, and for uniform germination.
MT0 SEEDS: A variety’s description followed by MT0-10 indicates that the seed offered for sale has 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 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.
TRANSPLANTS: Avg. 20,000 plants/oz.
PELLET STORAGE: Pelleting offers many advantages, but the pelleting process also shortens the shelf life of the seed. We recommend usingseed within one year of purchase. If you need to storeseeds until planting, protect them from heat and humidity in a cool, dark, dry place. If you prefer to store your seed in the refrigerator, be sure to place the seed in an air-tight container to protect it from fluctuations in humidity.
