I applied MAG-I-CAL on my lawn on April 19, 2014 for the first time along with Love Your Lawn - Love Your Soil. I must say - my lawn looks the best it has ever looked. I was preparing the lawn for a spring seeding which I did the following week. Since my lawn wasn't in horrible shape I figured my soil pH wasn't too bad so I didn't bother testing which I know is recommended. I really like Jonathan Green's approach to lawn care which starts by creating ideal conditions in the soil. Now, my lawn is beautifully dark-green in color and growing steadily. Thank You Jonathan Green!

I put Mag-I-Cal on my yard 4 weeks ago. Before I put it on I tested the Ph. It was 5.8 - 6. I tested my yard yesterday 4-3-2014 and the Ph was 5.2 -5.8. Whats the problem.

In response to the post on 4/4/14 - Typically you have to wait longer than four weeks to get the proper read and results for the lawn. Also it depends on what type of soil pH tester you used. If you used an inexpensive tester it may not have given you the most accurate reading. We recommend waiting until the end of April and testing the lawn again. If at all possible use a higher end tester or have the soil tested by your local extension agency. Thank you, Jonathan Green
