Jonathan Green 5M Mag-I-Cal for Acidic Soil

A highly soluble form of calcium that helps to rapidly raise your soil’s pH. Low soil pH causes weeds and moss to grow, while soil pH ranging between 6.2 to 7 will increase microbial activity, boost lawn color, reduce stress, and aid in water uptake. Can be applied anytime during the growing season. Safe for use around pets and kids. 5M bag equals 5 bags of lime; 15M bag equals 15 bags of lime.
