Description

(Lactuca sativa) Leaf. Oak-leaf type lettuce produces lustrous, deep red leaves. Very slow to bolt; the rich, red leaves and upright symmetrical form commend this one for market gardens as well as home gardeners who insist upon superior types. Also highly recommended for hydroponics cultivation and out-of-season low-tunnel production. Rare in this country, and very choice. This antioxidant-rich lettuce contains nearly a day's worth of vitamin A in just one 100-gram serving, more than any other lettuce we tested in 2020!

Growing Tips: Lunix lettuce performs best in temperatures around 60-80 F. It's important to maintain consistent moisture in the soil without letting it get waterlogged, as overwatering can promote disease. Enrich the soil with compost or well-rotted manure a week or two before planting to ensure it has the necessary nutrients. To retain moisture and regulate soil temperature, consider mulching with straw or compost.

When to Grow

Lunix lettuce is best planted in early spring or late summer to avoid the extreme heat of midsummer, which can cause the plants to bolt. Start sowing seeds directly in the garden as soon as the soil can be worked in spring, or in late summer about 6-8 weeks before the first expected frost. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow Lunix lettuce seeds 1/4 inch deep in well-prepared soil. If starting indoors, plant seeds 4-6 weeks before the last frost date and transplant seedlings when they are about 3-4 inches tall. Sow in thick bands for baby greens or space 8 inches apart for head lettuce.

How to Grow

Water your Lunix lettuce regularly to keep the soil consistently moist. Use drip irrigation or water at the base to avoid wetting the leaves, which can lead to fungal diseases. Fertilize with a balanced fertilizer high in nitrogen to promote leafy growth, but be cautious of over-fertilizing, which can lead to excessive leaf growth and weak plants. Regularly inspect for pests like aphids and slugs and employ organic pest control methods if needed.

How to Save Seeds

  • Lettuce is a self-pollinating annual, making it an easy crop for seed saving.
  • Choose the best and healthiest plants and allow them to send up flower stalks.
  • Once seed heads are dried and have turned a yellowish-tan color, cut the entire stalk and place in a bag.
  • Crush the seed heads in the bag and separate the chaff.
  • Store in an airtight container in the refrigerator for up to 4 years.
