Tips for Growing Lettuce


Growing lettuce is easy as long as you meet its basic growing requirements. Lettuce in general are cool weather plants and the easiest time to grow lettuce is in the early spring or fall.

You can plant seeds as soon as the ground is no longer frozen. Lettuce seeds can germinate in moderate to cool temperatures with a soil temperature of approx. 70 degrees F.

Lettuce also prefers the soil to be moist at all times. However, plants grown in really soggy soil will be susceptible to disease or mold, so frequent short waterings may be best for your lettuce.

Basics for How to Grow Lettuce:

  • Lettuce should be grown in well-drained soil with a good amount of organic content and soil should not be too acidic or lumpy
  • Plant your lettuce seeds in a sunny area or in an area with partial shade
  • Space seeds (approx. 6 inches apart to avoid transplanting) - this will depend on whether you are planting leaf or head lettuce
  • Cover seeds with 1/8 to 1/4 inch of top soil and moisten soil with water - make sure your lettuce seeds stay moist until they sprout
  • Seeds will germinate in 2 to 10 days. Leaf lettuce takes approx. 40 days from seed to harvest and head lettuce approx. 70 days from seed to harvest
  • Lettuce plants hate being moved, so thinning out seedlings might be better than transplanting your lettuce
  • Lettuce will benefit from a good layer of mulch as lettuce is shallowly rooted and can be easily uprooted

Lettuce is tolerant to some frost and light freezes, but too hot or dry conditions may cause your lettuce plants to turn bitter and bolt to flower.
