Description

• Parris Island Cos Lettuce is a vigorous, upright romaine with dark green leaves and a dense, white heart. its outer leaves are usually harvested as needed for garden fresh salads or a sweet, crisp addition to sandwiches, rather than the whole head being harvested at once. In addition to its long season and exceptional nutrition values, Parris Island is resistant to lettuce mosaic virus and tipburn.
• Lettuce grows best in cool weather in the spring and fall, but it can be grown in the summer, and all winter long in milder regions. Sow short rows every 2-3 weeks following the last average frost date for a continual harvest. Using a cloche, cold frame, or greenhouse over mid-late summer plantings can extend the harvest period right into winter.
• Water – Lettuce plants require about an inch (2.5 cm.) of water per week for optimal growth. If growing Parris Island cos lettuce during the hot summer months, they will require extra water to prevent bolting.
• Soil – Keeping the soil cool and moist with layers of mulch or straw will also help it grow through difficult weather. Keep in mind that like most lettuce types, slugs and snails can sometimes be a problem.
• Sunlight – Full sun to partial shade
• Temperature – Optimal soil temperature for germination: 10-22°C (50-72°F). Seeds should sprout in 7-15 days, depending on conditions. Lettuce seeds don’t sprout easily when the soil temperature is over 22°C (72°F) in summer.
