Why, When and How to Apply Lime to Your Lawn

Lime's primary role is to alter soil pH and offset soil acidity, which can improve the availability of plant nutrients. 2. Why apply lime? Lawns need lime when low soil pH starts inhibiting the availability of nutrients. Soil pH preferences vary between regional lawn grasses, but most grasses prefer soil pH between 5.8 and 7.2.
