How To Kill Fescue In Bermuda Grass?

If you have a lawn that is a mix of fescue and Bermuda grass, you know how difficult it can be to keep them both healthy and looking good. Fescue is an aggressive grass that can quickly overtake Bermuda grass, leaving you with a patchy, uneven lawn. Fortunately, there are steps you can take to kill the fescue and restore your Bermuda grass to its former glory. In this article, we’ll discuss how to kill fescue in Bermuda grass and get your lawn looking great again.

  1. Identifying Fescue in Your Lawn

Identifying Fescue in Your Lawn is essential for maintaining a healthy Bermuda Grass lawn. Fescue, a cool-season grass, is a common weed that can quickly take over your Bermuda grass lawn and prevent it from growing at its full potential. Fescue is identifiable by its fine blades, which are much thinner than those of Bermuda grass. Its color is usually lighter green than that of Bermuda grass and its blades grow in an upright position. In addition, Fescue has a clumping growth pattern as opposed to the spreading growth pattern of Bermuda grass. To further distinguish between these two species of grass, look at the root system: Fescue has an extensive root system while Bermudagrass typically has shallower roots that spread and tiller horizontally close to the soil surface.

  1. Benefits of Removing Fescue

Removing fescue from a bermuda grass lawn is an essential step in maintaining a healthy, aesthetically pleasing lawn. Fescue, if left unchecked, can disrupt the growth of bermuda grass and cause dead patches in your lawn. When it spreads too far, it can even kill off bermuda grass entirely.

When removing fescue from your bermuda lawn, there are several benefits you can reap. First of all, eliminating fescue helps to prevent the spread of disease and pests that may be attracted to its presence. Fescue also has a shallow root system which makes it an ineffective competitor for water and nutrients with other grasses like Bermuda. This means the removal of fescue can make sure that your desired grass receives enough water and nutrients to thrive and look lush.

Another benefit of removing fescue is that it allows you to control the appearance of your lawn more easily as well as reduce maintenance costs associated with weeding out unwanted plants. Fescue tends to grow faster than Bermuda grass so its presence requires frequent mowing in order to keep it under control – this can quickly add up over time and become quite costly. Removing fescue ensures that only the desired grass remains in your yard and reduces the amount of maintenance required overall.

  1. Killing Fescue with Herbicides

Killing fescue with herbicides is the most effective way of getting rid of it in a Bermuda grass lawn. Herbicides are chemical agents that act to restrict plant growth and they are available in both liquid and granule form.

When selecting an herbicide, make sure you choose one that specifically targets fescue, such as Fescue-Kill or Turflon Ester. These products contain active ingredients like 2,4-D and Dicamba that are designed to kill fescue without damaging your Bermuda grass lawn. You should also read the product label carefully and follow all directions for application.

For best results, apply herbicides when temperatures are above 65 degrees Fahrenheit (18 degrees Celsius). This will ensure the active ingredient is absorbed into the plant quickly and effectively. When applying herbicides, spray them onto dry foliage until the entire targeted area is evenly covered. If using a granular form of herbicide, spread it evenly over the entire targeted area using either a hand spreader or drop spreader.

After application, be sure to water your lawn thoroughly to activate the herbicide’s effectiveness and help it to enter the soil and reach its target plants. Depending on the type of herbicide you use, you may need to treat your lawn several times before all fescue has been eliminated. Be sure to read all labels for instructions on proper usage and follow any re-treatment guidelines for best results and safety.

Maintaining a healthy Bermuda grass lawn requires regular maintenance to ensure it has the best chance of growing and thriving. This includes properly fertilizing, mowing and watering the grass, as well as removing any weeds or pests that might threaten its health. Fescue is one of these unwelcome intruders, as it can quickly overtake a Bermuda grass lawn if left unchecked. To keep your lawn healthy and lush, you’ll need to regularly inspect your lawn for signs of fescue and then take action to kill it off before it takes root.

Start by examining the color and texture of your lawn; fescue can be identified by its higher growth rate compared to Bermuda grass, its thin blade-like leaves and light green coloration. If you notice patches of grass that don’t match these characteristics, you may have a fescue infestation on your hands. Once you’ve identified fescue in your lawn, you should act quickly to get rid of it before it spreads further and causes more damage.

Killing fescue with herbicides is an effective way to remove it from your lawn; an application of post-emergent herbicides such as glyphosate or 2,4-D will help control the spread without damaging the surrounding Bermuda grass. For maximum effectiveness, make sure to apply the herbicides directly onto the affected areas while taking care not to spray any other plants in the vicinity. As always when using herbicides, make sure to read all instructions before applying them on your lawn and wear protective clothing such as gloves, long sleeves and eyewear while doing so.

This means continuing with regular mowing and watering schedules as well as inspecting for pests or weed growth on a weekly basis – catching any potential issues early on will go a long way in keeping your Bermuda grass looking its best!


In conclusion, when it comes to killing fescue in bermuda grass, it is important to be able to identify the weed and understand the benefits of removing it. The most effective way to do this is through using an herbicide. Once the fescue has been eradicated, you should practice proper lawn maintenance techniques such as mowing regularly and fertilizing regularly to ensure a healthy bermuda grass lawn. With these steps combined, you can keep your lawn safe from any pesky weeds that try and invade your beautiful green grass!
