Lime or sulfur are common soil amendments applied to lawns and landscape areas to modify the soil pH. Lime is applied to soils that are acidic or low pH. In most cases, lime is applied at rate of between 5.0 to 8.0 lbs. per thousand square feet of lawn area. Our ExperiGreen soil amendment service is meant to modify the pH of your soil so your grass plants can better take up and utilize the nutrients applied to the lawn.
