Lettuce Romaine

Lettuce Romaine, also known as Cos lettuce, is a nutritious leafy green prized for its crisp texture and slightly bitter flavor. Growing this variety of lettuce provides a fresh and healthy addition to salads, sandwiches, and wraps, making it a valuable addition to any home garden.

Preparing for Growing:

• Selecting a planting location: Choose a planting location that receives full sun to partial shade. Ensure the area has well-draining soil and good air circulation.
• Soil preparation: Prepare the soil by loosening it to a depth of 6-8 inches and removing any debris. Incorporate organic matter such as compost or aged manure to improve soil fertility.
• Purchasing or preparing containers/pots: If growing in containers, select pots with drainage holes to prevent waterlogging.

Starting from Seeds Indoors:

• Seed preparation: No special seed preparation is required. Choose high-quality Lettuce Romaine seeds for optimal germination.
• Choosing suitable pots/containers: Utilize seedling trays or small pots filled with seed starting mix.
• Sowing and caring for seeds indoors: Sow lettuce seeds indoors 4-6 weeks before the last frost date in your area. Keep the soil consistently moist and provide adequate light, such as a sunny windowsill or under grow lights.
• Transplanting to larger containers if necessary: Once seedlings develop true leaves, transplant them into larger containers or outdoors if weather conditions permit.

Starting from Seeds Outdoors:

• Soil preparation: Prepare the garden bed by loosening the soil to a depth of 6-8 inches. Remove debris and incorporate compost for added fertility.
• Selecting appropriate timing and method for outdoor sowing: Sow lettuce seeds directly outdoors in early spring or late summer. Plant seeds 1/4 inch deep and 1 inch apart in rows spaced 12-18 inches apart.
• Caring for seeds outdoors: Keep the soil consistently moist until seeds germinate, typically within 7-14 days.

Growing in Containers/Pots:

• Selecting suitable plants for containers: Lettuce Romaine thrives in containers.
• Container and soil preparation: Choose containers with drainage holes and fill them with quality potting mix.
• Sowing or transplanting plants into containers: Sow seeds or transplant seedlings into containers, following spacing recommendations on the seed packet.
• Caring for container plants: Place containers in a location with partial shade to full sun, and water regularly to keep the soil evenly moist.

Transplanting to Garden:

• Soil and planting site preparation: Amend the soil with compost and ensure good drainage.
• Correct timing and method for transplanting: Transplant seedlings outdoors once they develop several true leaves, spacing them 12-18 inches apart.
• Post-transplant care: Water transplanted seedlings thoroughly and provide shade if needed to prevent wilting.

Plant Care:

• Watering: Keep the soil consistently moist, watering at the base of the plants to prevent fungal diseases.
• Fertilizing: Apply a balanced fertilizer according to package instructions once seedlings establish themselves.
• Weeding: Keep the garden bed or containers free from weeds to reduce competition for nutrients and moisture.
• Pest and disease management: Monitor plants regularly for signs of pests or diseases. Handpick pests like aphids and caterpillars, and treat fungal diseases with appropriate fungicides if necessary.

Harvesting:

• Determining when plants are ready for harvest: Harvest Lettuce Romaine leaves when they reach the desired size, usually around 45-55 days after planting. Harvest outer leaves individually for a continuous harvest or cut the entire plant back to 2 inches above the soil.
• Harvesting and storage guidelines: Harvest lettuce in the morning when leaves are crisp. Store harvested leaves in the refrigerator wrapped in damp paper towels for up to one week.

When to Start from Seeds by USDA Plant Hardiness Zones:

• Lettuce Romaine seeds can be started indoors or sown directly outdoors based on your USDA plant hardiness zone. In colder climates (zones 1-6), start seeds indoors 4-6 weeks before the last frost date. In warmer climates (zones 7-11), sow seeds directly outdoors in early spring or late summer for a fall crop.

Fast Facts:

• Planting depth: Sow seeds 1/4 inch deep in the soil.
• Seed spacing: Plant seeds 1 inch apart in rows spaced 12-18 inches apart.
• Plant spacing: Space transplanted seedlings 12-18 inches apart.
• Number of seeds per pot/container: Plant 2-3 seeds per pot or container and thin to the strongest seedling.
• Water preferences: Keep soil consistently moist, watering at the base of the plants.
• Sun preferences: Partial shade to full sun, with at least 6 hours of sunlight per day.
• Soil type and other important factors: Well-draining, fertile soil with a pH between 6.0 and 7.0. Incorporate compost for added fertility.
• Companion Planting: Lettuce Romaine grows well with herbs like dill, basil, and cilantro, as well as other leafy greens like spinach and arugula.
• Temperature Preference: Lettuce prefers cooler temperatures between 45°F and 75°F.
• Days to Germination: Lettuce Romaine seeds typically germinate in 7-14 days under optimal conditions.
• Days to Harvest: Harvest Lettuce Romaine leaves in 45-55 days from planting, or when leaves reach desired size.
