Brown spots in the lawn can be caused by many different factors and conditions. Dog urine, brown patch fungus, a dull lawnmower blade, and grubs are some potential culprits.
When you see brown spots on the lawn, you could be looking at several different kinds of problems. Pet urine, a dull mower blade, brown patch fungus, even grubs can all be culprits. Check out our list of symptoms and solutions.
Do you have a dog? Dog urine contains concentrated nitrogen, which can burn a lawn. Create a pit stop in your yard with mulch or pea gravel for your dog.
You probably have a dull mower blade. Dull blades shred the grass, damaging the ends. These damaged ends die and turn brown. Try sharpening your blade and see what results you get.
You could have Japanese beetles and grubs. Check to see if the leaves of your trees and shrubs have been eaten into a lacework. If so, apply Scotts GrubEx® to your lawn and mulched areas. Spray trees and shrubs with Ortho® Bug-B-Gon® MAX® Lawn & Garden Insect Killer.
You could have brown patch fungus. It loves hot, sticky weather. Brown patch grows in circular patterns sometimes several feet wide. Treat your lawn every other week with a lawn fungus control product such as Scott® Lawn Fungus Control. You'll need at least 3 applications. Only water once a week, since a wet lawn encourages the fungus.
You could have overfed your lawn. Water the burned area every 3 days with at least ½ inch of water for about 4 weeks. You don't want to fertilize again until the area perks back up.
