Where can I send a few lawn samples to determine the PH?
Montcalm County Michigan
The best way to determine your soil health (which includes pH) is to have your soil tested. A soil test can be purchased from MSU through the bookstore (link below) for a cost of $25. Or there are kits available at the Kent MSU office located at 775 Ball NE in Grand Rapids between 8 a.m. - 4 p.m.
Everything you need to send in the soil test sample is included in the packet. It takes about two weeks for results to be processed and your full soil test results plus recommendations are posted on line for easy reference. Hope that helps!
