Poor soil quality, fungus, dog urine or excessive mowing can make brown spots appear on your lawn. But there are still things you can do to try and solve the situation.
Brown patch disease can be another common cause for brown spots. This disease can be caused by excessive heat and humidity, particularly in the summer and early fall. To solve this issue, you should water your lawn very carefully. Since this problem can be caused by too much moisture, you should avoid watering your lawn during the night. The ideal time for doing that would be either before 10 a.m. or between 4 and 6 p.m. In case your grass remains humid all night, it thus becomes more vulnerable to pests or diseases.
Excessive amounts of nitrogen may also lead to brown spots. And too much nitrogen can be the result of dogs urinating on your lawn, so you should do something to avoid that.
Dethatching and aerating your lawn can be another great way to prevent brown spots. This helps plants’ roots better reach for the humidity, nutrients and the air they need in order to remain healthy and nice-looking. And using an organic grass fertilizer may be another great method to prevent such issues.
