Lettuce, a cool-season vegetable, comes in many varieties and can easily be grown in the home garden with the proper care. Determining the correct amount of fertilizer for a lettuce garden is dependent upon soil testing.
Have the soil tested to determine the amount of fertilizer and lime present in the soil. Lettuce grows best in soil with a pH between 6.0 and 6.7. Soil testing typically is conducted by a local cooperative extension office.
Types of Fertilizer
For soils with a pH between 6.0 and 6.7, add a 10-10-10 fertilizer. On untested soil, a gardener's best choice is to use a 5-10-10 formula.
For every 100 square feet of garden, use 3 to 4 lbs. of fertilizer. Mix at least half of the fertilizer directly into the soil with a rake at the time of planting. The remaining fertilizer can be applied as the lettuce grows, if necessary.
