The pH of my lawn

You can get a soil sample analyzed at your County Extension office (or at a private soil testing lab). pH for a lawn should be 6.0 - 6.5. Nutrients are present in quantities needed by lawn but not in toxic quantities at that pH. Also, microorganisms needed for good lawn growth and decomposition thrive at that pH. If the pH is too low, you should add lime. A lawn with a low pH will be predominantly red fescue (a grass that tolerates low pH) or moss if it is shady and moist enough.
