MAG-I-CAL® is a highly soluble form of calcium that helps to rapidly raise your soil’s pH, improving the health of your lawn by releasing trapped nutrients in the soil that feed the grass plants.
Low soil pH causes weeds, moss, and bare spots to grow, while soil pH ranging between 6.0 – 6.8 will re-energize your lawn, increasing microbial activity, boosting your lawn’s color, reducing stress, improving soil texture and aiding in water uptake. Using MAG-I-CAL® will also significantly improve your fertilizer’s effectiveness for a thicker, greener lawn with improved weed control.
MAG-I-CAL® comes in an easy to spread pellet form, can be applied anytime during the growing season, and is safe throughout the yard. MAG-I-CAL® is also concentrated, meaning one bag of MAG-I-CAL® equals up to ten bags of limestone, saving you time, money, and your back!
