In order to prevent brown spots in grass, one of the best practices to apply is to avoid watering it too often. The most recommended routine is that of watering your lawn every few days, and applying deep watering, i.e. about ½ inches for every watering session.
Reducing thatch can be another good method to prevent brown spots from appearing on your lawn. And to do that, you should aerate your soil in the early fall or late summer periods. Not only do you get rid of excessive thatch, but also solve the issue of compacted soil, which may also influence the state of your lawn, causing it to dry prematurely.
And, of course, you should apply the right kind of organic fertilizer. Providing your lawn with the much needed nutrients all year round can help prevent brown patches and thus you can enjoy a beautiful and resistant lawn for many years to come.
In order to prevent grass from becoming dry too quickly during the drought season, it is important to mow the grass higher than you typically do. Avoid walking on the lawn, to give it a chance to recover sooner. Grass clippings should be left on the lawn to ensure extra humidity.
