Earth Science Fast Acting Lime is made from finely ground, high quality, pelletized calcitic lime. It is primarily used to naturally raise the pH of soil. Soil pH directly controls how easily plants can absorb essential nutrients from the soil. When soil pH is too high or too low, it can lead to nutrient deficiencies and poor growth. A good target for most plants is 6.0 – 7.0.

Earth Science Fast Acting Lime releases quicker into the soil than natural limestone and will not leave dust behind during application. You can use it in the garden or on your lawn. When added to lawns, it will improve the color, resulting in a healthy, vibrant green lawn.

We stock Earth Science Fast Acting Lime in 40 lb. bags.

What does lime do for a lawn?

Adding lime to your lawn will raise the soil’s pH, lowering the soil’s acidity. The sweet spot for lawns in Northern Virginia is a soil pH between 6.2 - 7.0. Our local soils tend to be on the acidic side with a soil pH ranging from 4.5 to 5.5. Adding fast acting lime can raise the pH of the soil, helping the lawn to absorb essential nutrients like nitrogen, phosphorus and potassium from the soil.

How do I know if I need to add lime to my soil?

We recommend getting your soil tested. We can complete a pH test for you at the Plant Clinic if you bring in a 12 oz. jar of your soil. Virginia Tech also offers a more comprehensive soil analysis test with pH and nutrient values and recommendations. We offer the soil collection box for this test at the Plant Clinic. There is a fee associated with the analysis and payment instructions come with the collection kit. Finally, we also offer an at home DIY soil test kit. The DIY kit is available for purchase at the Plant Clinic and while it provides a quick result, the detailed analysis will not be as comprehensive as the test performed by Virginia Tech.

When should I add lime to my lawn?

We recommend liming your lawn either in the fall or early spring. Do not apply lime during extreme heat or on frozen ground.
