What Causes Brown Spots In A Lawn?

For most homeowners, having a beautiful, lush lawn is a source of pride. Unfortunately, things don’t always go according to plan. Sometimes, lawns develop brown spots, taking away from their beauty and negatively impacting your home’s curb appeal.

Before you can fix these brown spots, you need to identify the underlying issue that caused them in the first place. That way, you can take steps to deal with the issue so that your lawn can thrive again. Below is a list of some of the primary causes of brown spots in a lawn. Based on your situation, you should be able to figure out which problem is causing the brown patches in your lawn so that you can begin fixing them.

1. Dogs.

If you have a dog they could be causing the brown areas in your lawn. Dog urine contains high concentrations of nitrogen. When they urinate on the lawn, it can add too much nitrogen to the soil. This, in turn, can cause the grass to burn, turning it brown as a result. In essence, it is the same effect that would happen if you added too much fertilizer to the lawn.

The best way to deal with this problem is by training your dog to urinate somewhere else in your yard. For instance, you could create a small patch of gravel at the back of your yard for your dog to use as their own personal bathroom. Alternatively, you can also spray your lawn down with water right after your dog urinates to help dilute the nitrogen and minimize its impact on your grass.

2. Poorly drained soil.

Ideally, your soil should absorb water quickly, allowing it to penetrate down to the roots of your grass. Unfortunately, if your soil is poorly drained, the water may not soak in. Instead, it may sit on the surface of the soil, keeping your grass overly saturated. This can lead to brown patches in areas where standing water tends to accumulate.

To prevent this problem, try getting rid of any dips or indentations in your lawn by cutting a square around the affected area, pulling up the sod, and adding soil underneath. Alternatively, you can also try poking holes in the surface of the soil and filling them with sandy soil to help improve the drainage.

3. Fungal disease.

If your lawn is affected by a fungal disease, it can result in brown patches. If you have eliminated other causes and can’t figure out what is going on, take a sample from one of the brown areas to your county extension office to have it evaluated. They can tell you whether or not it is a fungal problem that is causing the issue. From there, you can come up with a treatment plan that will help you eliminate the fungus so that your lawn can be healthy again.

Now that you know what causes brown spots in a lawn, you can start taking steps to fix any problem areas in your own lawn. Fortunately, most issues that result in brown spots can be resolved at Discover Ziehler with their little bit of time and effort.
