Slow-bolting, flavorful one-cut red leaf. Conventional seed with NOP-compliant pelleting.

Each leaf shows beautiful color contrast between red, green, and yellow, making it a gorgeous addition to salad mix. A true mini, Rubygo holds its compact frame even after it matures. Ideal for sandwiches, as leaves are thick with a crunchy texture and excellent flavor. Great for salad mix and whole-head sales. Makes a perfect pair with Verigo. MT0-30.

Disease Resistance:

  • Downy Mildew (EU) races 16–27, 30–32 (High)
  • Lettuce Leaf Aphid

Nasonovia ribisnigri (High)Lettuce Mosaic Virus (Intermediate)

Specs:

  • Packet: 25 seeds

SCIENTIFIC NAME

Lactuca sativa

CULTURE

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. Sow every 2–3 weeks for a continuous supply of either full heads or salad mix.

PELLETED SEED

Pelleted 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.

PELLET STORAGE

Pelleting offers many advantages, but the pelleting process also shortens the shelf life of the seed. We recommend using pelleted seed within one year of purchase. If you need to store pelleted seeds 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.

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 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.

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.
