Days To Maturity
Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

Life Cycle
Life Cycle
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).

Breen Lettuce Seed
True compact, red, mini romaine.
Breen forms a very compact mini head early and is slow to become oversized. The short plant averages 8" tall and is a medium-bronze-red color. Though best for mini heads, it can also be used for cut-and-come-again harvest. Especially nice marketed with other mini romaine varieties. Utility Patent granted. MT0-30. Also available organic or with NOP-compliant pelleting.Disease Resistance:

SCIENTIFIC NAME:
Lactuca sativaCULTURE:
Lettuce is a hardy, cool-weather crop and can be planted with your earliest worked soil. It grows best at 60–65°F (16–18°C) and germinates best below 70°F (21°C), so careful variety selection is key for success in hotter weather.THERMAL DORMANCY:
Lettuce seed can enter thermal dormancy when exposed to high temperatures. Optimum germination results at soil temperatures of 60-68°F (16-20°C). The priming process in pelleted lettuce seeds broadens the temperature range in which the seeds will germinate, overcoming some of their thermal dormancy.DAYS TO MATURITY:
From date of spring/cool weather transplanting. Subtract 10–14 days for late spring/early summer/warm weather transplanting. Add about 14 days for direct seeding.TRANSPLANTING for HEAD LETTUCE: 3–4 weeks before field planting, sow in 128-cell trays barely covered with vermiculite or fine soil. If necessary, utilize shade and frequent misting to keep trays cooled below 75°F (25°C) during germination. Young plants properly hardened at least 3–5 days before planting can survive temperatures as low as 20°F (-6°C). Transplant iceberg, romaine, and butterhead lettuce 10–12" apart in rows 15–18" apart, other types 8–10" apart in rows 12–18", and mini heads as close as 6" in a grid.
DIRECT SEEDING for BABY LEAF: Seeds can germinate well in soils as low as 40°F (4°C) but often poorly above 75°F (24°C). Sow 4–6 seeds/inch in rows at least 2" apart. Cover lightly to 1/8" and firm gently. Dry soil must be watered to ensure coolness and moisture for uniform germination.
AVG. DIRECT SEEDING RATE:
For baby leaf: 1,000 seeds/16', 1 oz./400', 1 lb./6,400' at 60 seeds/ft.SUCCESSION PLANTING: Sow every 2–3 weeks for a continuous supply of either full heads or salad mix.HARVEST:
Head Lettuce: Cut at base, keeping wrapper leaves for handling loss. Consider cutting alternating plants to extend harvest window, allowing remaining plants to continue to grow. Pack heads in layers facing cut ends away. Wash off sap and cool immediately to prevent staining and dehydration. Baby Leaf: Harvest about 1" above the growing point when leaves reach desired harvestable length, about 3–4" long. Remove harvest debris to improve regrowth quality.STORAGE:
Keep cold at 35–40°F (1–4°C) with high humidity but free of standing water. Head Lettuce: Keep 14–20 days, less for delicate types like butterhead and oakleaf, and longer for lettuce grown slowly in cooler temperatures. For one-cut types, extend season in cold weather by holding cut heads in cooler up to two weeks to process into salad mix.MT0-30 SEEDS:
A variety's description followed by "MT0-30" 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 30,000 seeds.TRANSPLANTS:
