How to Add Lime for Lawn Care

Overview

Adding lime to the lawn will take an acidic soil and raise the pH value. In most all cases to accurately determine the pH value of the lawn, a soil sample must be taken. This sample is then sent to the local agricultural extension service for a chemical analysis. The homeowner will receive a comprehensive plan for adding lime and other fertilizers to enhance any lawn or garden bed.

Step 1

Take soil samples from your lawn area as per the instructions given to you from the extension service. In most applications, a small sample of soil is taken from multiple locations across the lawn. Allow the soil samples to fully dry. Mix the clots of dirt together. Place the final soil mix in an extension service- provided container. Obtain the results in three weeks to four weeks.

Step 2

Apply the recommended agricultural lime to the lawn area by using a fertilizer spreader. Set the spreader to the predetermined dosage. New lawns may require up to 100 lbs. of lime per 1,000 square feet. This liming is generally added before any grass seed and is cultivated into the bare soil. Established lawns will use less than 35 lbs. of lime per 1,000 square feet. The lime will take some time to work into the soil through growing grass.

Step 3

Water the lawn as usual, or approximately 1 inch of water every week. Adjust your watering to your local rainfall. Continue to water in the lime until all signs of the lime have disappeared and you can no longer see a white powder below the grass and at the soil level.

Step 4

Conduct another soil test six months after the original application to check on the soil pH level. Follow the chemical recommendations from the testing laboratory.
