3 Reasons for Brown Spots on Your Lawn

Brown, dead grass

Now that summer is here, you might be noticing that your lawn isn’t as green as it used to be. Brown spots on your lawn are a common issue that many homeowners face. There are a few different reasons you may be encountering this problem. Here’s what you need to know.

1. Grubs

Grubs are beetle larvae that eat the roots of your grass, causing it to die. If you have grubs, the ground will feel slightly spongy when you walk on it in addition to brown spots on your lawn. Grub infestations can crop up due to weather conditions, improper lawn care, and changing moisture levels in the soil.

A grub problem will only get worse if not properly treated, and grubs attract predators such as raccoons that are all too happy to dig up your lawn in pursuit of food. Luckily, there are many ways to deal with grubs. If you think you have grubs in your lawn, give us a call and we can help.

2. Thatch

Thatch is a buildup of dead materials near the roots of the grass, clogging the root system and preventing your lawn from receiving the right amount of water and nutrients it needs to thrive. Eventually your grass will start growing roots in the thatch layer, which causes it to dry out and causes brown spots on your lawn.

Thatch tends to be densely compacted, so you can usually tell if thatch is the reason behind the brown spots on your lawn by trying to insert a screwdriver or your finger into the soil through your grass. If you’re met with resistance, thatch is probably the culprit.

Aerating your lawn regularly can help prevent thatch buildup and will allow your grass to access the nutrients it needs to thrive. It’s important to do this regularly to interrupt thatch before it kills your grass.

3. Brown Patch Disease

Brown patch is a fungal disease that affects grass during particularly hot and humid weather. If caught early, grass affected by brown patch disease can sometimes recover. However, often the affected grass dies completely, leaving dead, brown spots on your lawn.

You can try to avoid brown patch disease by keeping up with your watering and making sure your fertilizer isn’t too high in nitrogen. Aerating your lawn can also help. Unfortunately, brown patch disease is largely dependent on the weather, which is out of your control.
