Growing Tips

  • 1Lettuce thrives in full sun but can tolerate partial shade, especially in warmer climates.
  • 2Water consistently to keep the soil moist but not waterlogged, as lettuce has shallow roots.
  • 3Use well-draining, fertile soil rich in organic matter, and space plants about 6 to 12 inches apart to ensure good air circulation and reduce the risk of disease.
  • 4To manage pests, consider using row covers or natural deterrents like neem oil.

How to Harvest

  • 1Harvest lettuce in the morning when leaves are crisp and full of moisture.
  • 2For leaf lettuce, cut the outer leaves about an inch above the base, leaving the center intact to allow regrowth.
  • 3For head lettuce, cut the entire head at the base, being careful not to disturb surrounding plants.

Step 5

Saving Seeds

How to Save Seeds

Saving seeds from a lettuce plant is easy and rewarding, even for new growers! Simply let a few of your healthiest lettuce plants bolt, meaning they grow tall and produce flowers. Once the flowers turn fluffy and dry, gently pull them off and collect the tiny seeds inside. Let the seeds dry for a few days in a cool, dry place, then store them in a labeled envelope or jar in a cool, dark spot until you’re ready to plant again. With just a little patience, you’ll have your own homegrown seeds for next season—anyone can do it!
