DIRECTIONS * Common Names: Super Red Romaine Lettuce Latin Name: Lactuca sativa Type: Leafy Green Life Cycle: Annual USDA Zones: 3 - 9 Stratification: Not required Germination Ease: Easy Sunlight: Full Sun to Partial Shade Moisture: Prefers consistently moist, well-drained soil Soil: Rich, well-drained soil with a pH between 6.0 and 7.0 Height: 10-12 inches Spread: 8-10 inches Color: Deep red leaves Bloom Season: N/A (grown for leaves, not flowers) Companion Plants: Suitable companions include carrots, radishes, and strawberries. Potential Toxicity: Non-toxic to humans and pets Climate Adaptability: Prefers cooler temperatures and is adaptable to a wide range of climates; ideal for spring and fall growing seasons. ~ Sowing ~ When to Start Inside: Start seeds indoors 4-6 weeks before the last expected frost date. When to Start Outside: Direct sow seeds in early spring as soon as the soil can be worked, or in late summer for a fall crop. Sowing Instructions: Sow seeds 1/8 inch deep in well-drained soil. Planting Depth: Sow seeds 1/8 inch deep. Watering: Keep the soil consistently moist but not waterlogged. Lettuce prefers evenly moist soil to avoid bolting and maintain tender leaves. Light and Temperature: Super Red Romaine prefers cooler temperatures between 60-70°F (15-21°C). It can tolerate some shade, especially in warmer climates, to prevent bolting. Germination: Seeds typically germinate in 7-10 days. ~ Transplanting Seedlings Outdoors ~ Timing: If starting seeds indoors, transplant seedlings outdoors when they have 4-6 true leaves and after the risk of frost has passed. Location: Choose a sunny location with well-drained soil. In warmer climates, partial shade can help prevent bolting. Spacing: Space plants 8-10 inches apart to allow for adequate growth and air circulation. Transplanting: Gently transplant seedlings into the prepared soil, ensuring the root ball is covered and the plant is stable. Water well after planting. ~ Growing ~ Watering: Water regularly to keep the soil evenly moist. Mulching can help retain soil moisture and keep roots cool. Fertilizing: Lettuce benefits from a balanced fertilizer or compost worked into the soil before planting. A light side-dressing of compost or fertilizer can be applied every few weeks during the growing season. Pest and Disease Management: Monitor for pests such as aphids, slugs, and snails. Use organic pest control methods such as insecticidal soap or diatomaceous earth. Ensure good air circulation to prevent fungal diseases. Maintenance: Harvest leaves as needed by cutting them off at the base of the plant. This will encourage new growth and extend the harvest period. ~ Harvesting ~ When to Harvest: Super Red Romaine can be harvested when the leaves are crisp and fully colored, typically 55-65 days after sowing. How to Harvest: Cut the entire head off at the base or pick outer leaves as needed, allowing the inner leaves to continue growing. Drying and Storing: Lettuce is best used fresh. For short-term storage, keep harvested leaves in the refrigerator in a plastic bag or container. ~ Seed Saving ~ Allow one or two plants to bolt and produce seeds. Once the flower heads have dried, collect the seeds and store them in a cool, dry place for future planting. ~ Additional Information ~ Forage for Pollinators: N/A (Lettuce is grown for its leaves, not flowers) Origin: Lettuce is native to the eastern Mediterranean region and has been cultivated for thousands of years for its edible leaves. Nomenclature: The genus name "Lactuca" comes from the Latin word for milk, referring to the milky sap produced by the plant. The species name "sativa" means "cultivated." History: Romaine lettuce varieties have been cultivated for centuries and are prized for their crisp texture and mild flavor. Super Red Romaine is a striking heirloom variety known for its vibrant color and nutritional benefits. Potential Toxicity: Non-toxic and safe for consumption by humans and pets. Climate Adaptability: Prefers cooler temperatures and can be grown in spring and fall in most regions. In warmer climates, it may require partial shade and more frequent watering to prevent bolting.
