Applying lime to home lawns increases the pH level of soil. The soil pH level is maintained between 6.0 and 7.0. A correct pH level utilizes fertilizer efficiently. Determining the amount of lime and fertilizer is best done through a soil test. Combining these materials in one application consists of applying the correct type of lime. Pelletized limestone mixes well with most all fertilizers in a single application. Lime is typically applied in the fall of the year, with the growing season's last fertilizer application.
Collect soil samples from several locations around the lawn area. Mix the soil samples. Allow the soil to dry. Deliver the final soil sample to your local agricultural extension service for analysis.
Mix the pelletized limestone and lawn fertilizer together in the 5-gallon bucket. Follow the ratios for the application rate based upon the soil test results.
Fill the drop spreader from the 5-gallon bucket. Set the drop spreader according to the soil test results for application rate.
Run the drop spreader over the lawn in a single direction. Do not overlap the lime and fertilizer application, as this will burn the grass.
Irrigate the materials immediately into the soil.
