If you see localized dry spots in your lawn, walk across them to determine if they are hard under foot. If so, this is due to a lack of water and could signify a lack of coverage in your irrigation system or your lawn sprinklers. Contact your irrigation company or adjust your sprinkler coverage to ensure that the area is getting adequate water.
If the brown area feels the same as the green portions of your lawn when you walk across it, then you could be dealing with an insect or a disease problem.
A proper diagnosis would determine the best course of treatment. Be sure to contact us so that we can come out to identify the problem and recommend a treatment to bring your lawn back to health.
