Organic Non-GMO Lettuce Seeds::Organic Non-GMO Red Leaf Lettuce::Organic New Red Fire Lettuce

Organic New Red Fire Lettuce  Organic Non-GMO New Red Fire Lettuce - OPEN-POLLINATED

Popular among growers for its uniformity, intense color and bolt-tolerance. Large, loose heads are green at the base and very dark red at the ruffled leaf edges. Retains its crisp fresh flavor throughout the season. Superior to Red Sails for full size heads. Available as raw and pelleted seed. All-season lettuce · Bolt-resistant (Lactuca sativa)

Days to maturity: 55 days
Disease Resistance: Tip Burn, Bottom Rot, Downy Mildew, MT0-10

Please note: Our pelleted lettuce seed has been primed for faster and more uniform emergence. Priming is a process in which the seed is placed in a warm, moist environment to initiate germination, then dried down again before germination occurs, ensuring uniform emergence when the seed comes in contact with moisture. Pelleted seed has a shorter shelf life than raw seed and will remain viable for one year if properly stored under cool and dry conditions.

Organic Lettuce - Growing and Seed Saving Info

Printable version of this page

Lettuce (Latuca sativa) is cool season annual in the Compositae family, which includes endive, escarole, chicory, globe artichoke, sunflower, Jerusalem artichoke, salsify, and burdock.
  • Looseleaf- var.crispa.  First to maturity, these fast growing lettuces do not form a head.  Good for babyleaf culture.
  • Butterhead - also known as bib, or Boston, this type forms a loose head with slightly oily leaves. Beautiful, sweet and tender, but bruises and tears easily.
  • Romaine – var.longfolia.  Romaine forms a tall dense upright head with a tender heart. It tolerates warm temperatures and is less prone to bolting.
  • Iceberg – var. capitata.  The fussiest type to grow, iceberg will form a compact round head if given a long cool season. It bolts easily if stressed.
Soil Requirements
Choose cool, well drained, loose soil with pH 6.2-6.8. Lettuce is sensitive to low pH.  Use 50-75lbs Nitrogen/acre, ~150 Phosphorus and Potassium/acre. Sidedress with N 3-4 weeks after planting. With transplanting, use 2lbs/50 gallons starter fertilizer, 4-8oz per plant.
Full sun to partial shade
Seeding Depth
1/8”, seeds require minimum amount of light for germination.
Seeding Rate
Babyleaf - ~60 seeds/ft, in 2” bands. Full size - ~3 seeds every 8-10”.
Plant Spacing
Babyleaf – continuous band. Full size – 8-12”
Row Spacing
Babyleaf - Ύ” between bands, 16 rows/36” bed. Full size - 12-18” or 3 rows/36” bed, 5’ centers.
When to Sow
Lettuce can be seeded in the spring as soon as the soil can be worked. Days to maturity are from direct seeding in spring conditions, subtract 10-14 days if transplanting, subtract 7-10 days if planting in summer conditions, add 20 days if planting late summer-fall In certain areas, lettuce can be grown throughout the summer by choosing varieties which are heat tolerant; however, many lettuce varieties have difficulty germinating in soils above 75°F.  Start transplants 3-4 weeks before setting out.  Sow seeds 4 per inch in flats or small-cell plug trays, barely covering with fine soil.  If sowing into flats, transplant 2 weeks later into plug trays, pots, or into another flat at 1-2” apart. 
Other Considerations
Harden off seedlings by reducing water and temperature for 2-3 days before transplanting. 
Frost Tolerant
Choose cold tolerant varieties to withstand light late-season frosts. 
Drought Tolerant
Keep moisture levels even. Drought stress can cause bolting.
Heat Tolerant
Choose heat tolerant, bold-resistant varieties (such as Batavian types) for summer plantings.
Seed Specs
24,000 seeds/oz avg. M= 1,000, MM=1,000,000
Seeding Rate
Baby Leaf - 96M seeds/100’ bed (~ 4 oz), 960M seeds/1,000’ bed (2.5 lbs), 7.7MM seeds/acre (~20 lbs), using ~960 seeds/ft, 16 rows/bed, 36” beds, 6’ row centers. Full Size - 360 plants/100’ beds (~1/32 oz), 3,600 plants/1,000’ beds (1 oz), using 10” spacing, 3 rows/36” bed, 5’ center beds. 31M plants/acre (~2 oz), using 10” plant spacing. These specifications are meant to be general guidelines for the particular application as noted. They can be loosely applied across the board for lettuces/mixes found in this section.
Seed Coating / Pelleting Info
Some of the varieties we carry receive an organic film coating applied to the seed, which make the seed easier to see during planting.
Cut lettuce holds best when harvested in the morning and cooled rapidly.  For salad mix or baby leaf production, harvest individual leaves when they reach desired size, or cut evenly across the bed making sure to stay above the growing tip.  For a continuous harvest, sow lettuce every 3 weeks.
Store just above freezing temperatures with 98% humidity.
Pest Info
  • Tarnished Plant Bugs cause brown scarring on stems. Romaine is especially susceptible.
  • Cabbage looper and cutworms can be controlled by Bacillus thuringiensis (such as Dipel DF, see Supplies) and/or spinosad (such as Entrust™), preferentially in rotation with one another to prevent selection of resistant individuals (check with your certifier before applying).
  • Leafminers burrow underneath the skin and leave weaving, translucent trails. They are usually controlled by natural enemies.
  • Slugs and Snails can be baited by beer traps. Practice clean cultivation and avoid mulch.
Disease Info
Many lettuce diseases are best prevented by production practices that maximize airflow around heads to stimulate rapid drying. Many varieties have been bred to have disease resistance.


Downy Mildew (race specified, if known), TB: Tip Burn, WM: White Mold, BHR: Bacterial Head Rot, BR: Bottom Rot, HS: Heat Stress, LMV: Lettuce Mosaic Virus, APH: Aphids,
  • Drop (Sclerotinia sclerotiorum, also called white mold). Grow on raised beds, rotate crops with grass.
  • Bottom rot (Rhizoctonia solani). Select plants with upright growth habit. Take care not to set seedlings too deep.
  • Lettuce mosaic virus (LMV) is highly seed-borne. Choose a reputable seed source. MTO-10, MTO-30: 10,000 or 30,000 seeds were tested for the presence of Lettuce Mosaic Virus, none was found. A disease-free test does not guarantee a seed lot to be disease-free, only that no pathogen was detected in sample.
  • Damping-off (caused by a number of soil-borne fungi) Avoid overwatering when plants are young.
  • Downy mildew (Bremia lactucae)
Seed Saving Instructions
Self-pollinated. Lettuce varieties will not cross pollinate with each other even at short distances, but beware of any wild lettuce which can cross with lettuce. Allow plants to "bolt" and eventually flower. Under wet conditions lettuce plants may need to be covered with a rain cover or grown in a greenhouse to prevent fungus from infecting the plant and seed heads. Carefully shake the seedheads into a paper bag to allow the mature seeds to be collected while leaving the immature seeds and flowers to keep growing. Gather every few days until no more seeds remain. Also, you can simply harvest the entire plant when about half of the seeds are mature and allow the rest to mature inside by standing up the plants in a box and on a cloth or tarp. Use an 1/8" screen to help with cleaning. Lettuce seed can remain viable for 3 years under cool and dry storage conditions.
