This Mag-I-Cal Plus Soil Food for lawns by Jonathan Green is formulated for those who have soil pH that needs to be lowered. This means that your soil test shows your pH is registering greater than 7.3 on the scale. This product is designed to help bring that pH down with continued use. (recommended usage is spring and fall for 24 months then re-test).

Be sure you get the right product - I carry a similar product in a black bag that is designed to RAISE soil pH. This listing you are reading here is the PURPLE bag is will lower your pH. We can't do exchanges so please be sure you get the right one.

From the Manufacturer:

Jonathan Green Mag-I-Cal® Plus for Lawns in Alkaline & Hard Soil contains sulfur and calcium sulfate dihydrate which lowers soil pH, is important to cell development and is vital to many grass plant functions. Poor soil that is hard and compacted is often the problem when it comes to growing a great lawn.

When soil is too alkaline and compacted, air, water and nutrients cannot get down to the roots, and the grass will not grow properly. Lawns thrive in slightly acidic to neutral soil with pH levels between 6.2 and 7.0. In soils with pH readings of 7.0 to 9.5, weeds thrive and grass becomes light green and spindly. Additionally, Mag-I-Cal® Plus helps to break up clay and compacted soils. This improves root penetration and promotes growth by increasing biological activity and releasing nutrients trapped in the soil.


Directions:
When to Apply:

  • Best applied during the growing season when the soil is not frozen.
  • Safe to apply when seeding or sodding.
  • Spread the product on a dry lawn soon after mowing.

Apply:
  • For best results, rake the lawn vigorously prior to application.
  • Use a rotary or drop lawn spreader. To select the proper setting see the Spreader Settings section in the accordion below.
  • Apply around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow an overlap to avoid gaps in coverage.

Post-Application:
  • To avoid staining, sweep any excess granules off of hard surfaces and back onto the lawn.
  • Irrigate the treated area after application for 15-30 minutes for best results.
  • Once watered, wait a day to mow the lawn to give the product time to activate.
  • For soils with a pH higher than 7, repeat applications twice a year.
