Description
Jonathan Green Mag-I-Cal® for Lawns in Acidic Soil is designed to quickly raise and balance soil pH so grass can grow thicker and healthier. Lawns grow best when soil pH is slightly acidic to neutral, between 6.2 and 7.0. When soil becomes too acidic, grass may look pale and weak while weeds thrive. Mag-I-Cal® helps restore proper soil conditions so your lawn can absorb nutrients more effectively.
This advanced formula contains soluble calcium that works faster and more efficiently than traditional lime. One bag of Mag-I-Cal® can provide the pH-adjusting power of up to 15 bags of limestone. It also includes humates that stimulate beneficial soil microbes, helping improve soil health and support stronger root growth for a greener, healthier lawn.
