Benefits and nutritional information:

  • Lettuce is not eaten for its nutritional content, although it does contain significant levels of vitamins and minerals. Nonetheless, it is 95% water and very low in calories.


  • Lettuce seeds are sown directly into garden rows.
  • The seeds are quite small and care must be taken not to plant too many of them since it makes the job of thinning difficult.
    • One recommendation is to mix the seeds with fine, dry soil before sowing.
  • Seeds should be planted 1/4” deep, in rows 24” apart.

When to plant:

  • Lettuce is among the first vegetables to be planted in our area.
  • The seeds can germinate when soil temperature is 35 degrees, and it has a 70% germination rate at only 45 degrees.
  • Seeds can be planted about once a month for a steady supply.
  • Summer planting will yield leaves that taste bitter, and the plants are prone to bolting.
  • Lettuce grows well with cucumbers, carrots and radishes.

Thinning, training

  • As plants begin to grow, thin out smaller, weaker ones.
  • Eventually spacing of lettuce plants should be 8” to 12”.

Signs of over-watering, nutrient deficiency

  • Lettuce requires a constant supply of water while growing;
    • however, soil that’s waterlogged with prevent roots from absorbing water or nutrients and the plants will die out.
  • With its shallow root system, lettuce may benefit from an extra application of a balanced (5-5-5) fertilizer every 3 weeks or so once it begins producing a crop.

Pests and pest controls


  • With leaf lettuce, you can harvest outer leaves and the plant will continue to grow and re-sprout more leaves.
