How to Plant Romaine Lettuce from Seed

When to Plant Seeds

  • Spring Planting: Start seeds indoors 4-6 weeks before the last frost, or direct sow 2-3 weeks before the last frost.
  • Fall Planting: Sow seeds 8-10 weeks before the first expected frost.
  • In mild climates, romaine can be grown year-round with adequate shade in summer.

Preparing for Planting

  1. Choose a location with full sun and well-draining soil.
  2. If planting in containers, use a pot at least 6 inches deep with drainage holes.
  3. Work compost or organic matter into the soil before planting.

Sowing Seeds Outdoors

  1. Sow seeds 1/4 inch deep in rows spaced 12-18 inches apart.
  2. Thin seedlings to 6-8 inches apart once they reach 2-3 inches tall.
  3. Water gently to keep soil moist, avoiding overwatering.
  4. Germination takes 7-14 days in optimal conditions.

Transplanting Seedlings

  1. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days.
  2. Transplant when plants are 3-4 inches tall, spacing them 6-8 inches apart.
  3. Water immediately after transplanting to help roots establish.

Pro Tip

For crisp, tender romaine lettuce, keep the soil consistently moist and harvest leaves from the outside first to encourage continuous growth. To prevent bitterness, provide partial shade in hot weather and water in the morning to keep plants cool throughout the day.

Bonus: Succession plant every two weeks for a steady supply!

Companion Plants

Getting to know your Romaine

Romaine lettuce grows in an upright formation, with long, sturdy leaves that range from light to dark green. The leaves have a slightly bitter taste, with the ribs providing a refreshing crunch. The plant can reach heights of 8-12 inches (20-30 cm) and typically forms a loose head rather than a compact, round one like iceberg lettuce.
