The Ultimate Guide to Identifying, Treating, and Preventing Lawn Fungus

A healthy lawn is an essential part of a great landscape. It enhances your property's curb appeal, adds to your home's resale value, and enables you to enjoy an outdoor space where your family can relax, entertain, and play. While a lush, green lawn is a homeowner's dream come true, the reality is that all lawns are susceptible to common diseases caused by fungi.

Lawn fungus can be difficult to control, so it's important to know how to spot the symptoms of fungal diseases and treat them before they get out of hand. Texas' leading lawn care expert, Integra Lawns, asserts that early detection and prevention are the best defense against lawn diseases that are caused by fungi. They are also pleased to share some useful information on the most common fungi that affect lawns in Texas, along with prevention tips and treatment recommendations.

Types of Lawn Fungal Diseases in Fort Worth, TX

Here are some of the most common types of fungi and lawn diseases that affect lawns in Texas:

Snow Mold – Snow mold can be recognized by unsightly white patches in your yard that resemble snow drifts as well as a distinct musty odor. Snow mold is caused by a fungus that thrives in cold weather. It can be particularly problematic for lawns located in northern Texas, but it may also occur in southern parts of the state.

Take-all Patches – Take-all patches are caused by a fungus that damages lawn grass, resulting in irregularly shaped brown spots. This lawn disease thrives during cool or wet weather. If you notice that your lawn is turning brown in circular patches during the spring or fall, the take-all fungus may be to blame.

Red Thread Disease – While red thread disease does not kill the grass in your yard, it can cause unsightly brown patches and bald spots. This fungus is particularly destructive because the spores it leaves behind continue to reproduce even after they're dead. Red thread disease is most common during periods of high humidity, though it may also occur from time to time without any apparent reason.

Rust Disease – Also known as leaf spot disease, rust disease is characterized by reddish-brown spots on the grass. This lawn disease is prevalent during spring and early summer following periods of rainy weather. If left untreated, the spots will grow and turn into large brown or black patches on your grass.

Dollar Spots – Characterized by small, circular spots of yellow or brown grass, dollar spot is a fungus that thrives in moist conditions. It can cause large patches of damage to your lawn and the surrounding landscape if left untreated. Dollar spots are also referred to as mosaic disease or leaf scald.

Fairy Rings – Fairy rings are caused by a type of fungus that forms vibrant circles in your lawn. They can be found anywhere from Texas' southern locales to its northernmost regions. Fairy rings have a distinct, circular shape and are generally green or brown in color but may also appear as yellow or black rings.

Mildew – Mildew is the name given to patches of white moldy grass that are usually found in and around your yard's trees. This grass disease naturally occurs during periods of high humidity.

What Causes Fungi to Invade Your Lawn?

There are a number of reasons why fungi may invade your lawn. Some of the most common causes include:

  • Overwatering
  • Mowing too short
  • Using too much fertilizer
  • High condensation and humidity
  • Your soil is too compacted

Protecting Your Lawn Against Fungal Disease

While it may be difficult to prevent lawn fungus altogether, there are a few steps you can take to protect your grass from common fungi and preserve the health of your lawn.

First and foremost, it's important to make sure you aren't overwatering your yard. Overwatering can cause your grass to rot and increase the likelihood that fungi will infect it. Another thing you can do is to make sure you're mowing your lawn at the right height. Do not cut your grass too short because that invites disease and fungus growth. As for fertilizing, don't overdo it. It's best to use a little fertilizer rather than a lot, as this can promote nutrient deficiencies in your lawn that may result in fungus. Furthermore, you can reduce the amount of moisture in your yard by mulching around plants and trees. This could prevent condensation that may encourage fungi to grow.
