MAG-I-CAL® for Acidic Soil 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 your time, money, and your back!
MAG-I-CAL® is the missing ingredient in your lawn care program that makes everything else work better! Learn more: the importance of pH!
If your pH is below 7.0, apply Mag-I-Cal for lawns in acidic soil:
- If pH is 6.0 – 6.4, apply MAG-I-CAL once a year
- If pH is 5.6 – 5.9, apply MAG-I-CAL in the spring and fall
- If pH is 5.1 – 5.5, apply MAG-I-CAL every other month until pH is above 5.5, then follow above suggestion
- If pH is 5.0 or below, apply MAG-I-CAL at 1.5 times the regular rate for three consecutive months. Two weeks after the third application, test pH then adjust application schedule accordingly.
