Many homeowners cultivate a type of grass called centipede lawn grass in South Carolina and more for decorative characteristics and durability. Centipede grass prefers areas with full sun or some partial shade because of its long, thin blades and deep green leaves.
It grows well in wet and dry conditions and can be planted in clay or loam soil. Centipede grass is a hardy, pest and drought-resistant plant, so often used as a groundcover or a border plant for landscaping projects.

It may be essential to remove centipede grass from your lawn. While most people deal with broadleaf weeds, you can use many approaches to removing centipede from Bermuda grass without harming other grass and plants.
In our guide, you can learn more about what kills centipede grass. By the end, you’ll have enough options to treat your entire lawn and end up with a new lawn for mowing that looks the same during the summer months of the growing season.
How To Control Centipede Grass
Understanding this grass is one step toward effective control or removal of the grass from your yard. In mild-winter climates, centipede grass (Eremochloa ophiuroids) is frequently planted as turfgrass.
It thrives in zones 8 and 9 of the U.S. Department of Agriculture’s plant hardiness map. It usually perishes when temperatures fluctuate by as little as 5 degrees Fahrenheit for an extended period or when temperatures alternate between cold and warm.
But if it is thriving where you don’t want it, and can’t freeze it, you can kill it with a readily accessible chemical. (Read Does Mulch Have Manure In It)
Using a Liquid Herbicide
The chemical that will kill centipede grass is Glyphosate. Garden centers and hardware stores readily carry half a dozen Glyphosate commercial products.
Make sure Glyphosate is the first active ingredient when you purchase any herbicide.
- Depending on the manufacturer’s formula, a standard dilution rate is 2 2/3 ounces per gallon of water.
- Remember to follow dilution directions and warnings on the product label.
- Adding 4 pounds of ammonium sulfate per gallon of water to Glyphosate makes it more effective.
- Alkaline water above pH 7 is also helpful as Glyphosate becomes more effective with 4 to 6 pH water.
- The chemical should be mixed and poured into any sprayer, from handheld to backpack sprayers, and more significantly.
Another reason to alter soil pH is that centipede grass can’t survive in neutral soil.
When to use herbicides?
As important as the product you use is timing. As a perennial warm-season grass, centipede grass is most active from late spring to early fall when there are warmer temperatures around.
The grass stops growing in the fall as temperatures drop. Thus, you need to apply Glyphosate to actively growing centipede grass where it can absorb the post-emergent herbicide easily to be effective.
The ideal time to apply the herbicide is in the summer or fall when you can see results about a week after applying your Glyphosate.
Glyphosate should be applied in the late afternoon on a sunny day with no wind. Higher temperatures and sunny days produce faster absorption. Applying Glyphosate right before it rains is pointless because the rain will wash the chemical off before it has a chance to be absorbed.
Protective clothing and eyeglasses should be worn when spraying Glyphosate, a toxic chemical. At the time of application, any pregnant women should stay clear. Keep children and pets out of the spraying area until the chemical has dried.
Be careful when applying the chemical around landscape plants, as Glyphosate can kill flowering perennials, shrubs, and trees. Any light wind can carry the chemical to nearby plants and yards across the street or blocks away, so set the spray nozzle to a coarse spray, as this can reduce spray drift and direct the weedkiller to where you want it.

How To Choke Weeds With a Healthy Lawn
A strong, thick turf of this type is the best way to prevent centipede grass or any other weed from growing on your lawn. Weeds can’t hold because of a strong turf, which will outcompete them. This happens over time with appropriate cultural techniques, such as the proper irrigation schedule, mowing heights, and fertilizer applications.
Keep your Zoysia’s height all year long between.5-2 inches, per recommended grass care techniques. Additionally, Zoysia needs about one inch of water per week. Therefore, avoid overwatering your grass because doing so increases the risk of illness.
Regular fertilizer will also keep that your Zoysia has access to all the nutrients it needs to stay strong and healthy throughout the various seasons of the year.
You can buy a fertilizer plan to deliver nutrients to your lawn and other plants effectively. It has specific fertilizer boxes for the early spring, summer, and fall growing seasons.
Additionally, each box includes three different fertilizer bottles with various nutrient ratios. Instead of a liquid, you can also purchase these as granular fertilizer. You can also use a mulch to choke out centipede grass by preventing it from filling any sunlight, or you can use zoysia grass plugs to cover any bare spots. (Read St Augustine Grass Seeds Guide)
Because there is no competition for soil space, bare spots present a chance for weeds and other unwanted grasses to spread. In addition, they may be brought on by disease or shade, and thus, you may need a different disease control plan.
Filling those spots with other plants will help your grass continue to outcompete unwanted weeds.
How to Spot Treating Using a Selective Herbicide
In more challenging situations, there may be nothing else to do but use chemicals to eradicate the unwanted grass.
However, it’s crucial to use a herbicide at the proper time of year. Any weed killer used for weed control should not be applied during the summer, significantly when warm temperatures exceed 85 degrees, as this will burn your lawn and harm your grass.
A selective post-emergent herbicide weed killer only kills the weeds listed on its label. Avoid using non-selective herbicides because they will kill any plant they come into contact with, including your grass.
When applied correctly, selective herbicides with active ingredients treat Bermuda and centipede grass on a zoysia lawn without harming the lawn.
Spot Treating Using Non-Selective Herbicides
As was already mentioned, a non-selective herbicide weed killer will kill any plant it comes into contact with. This includes the grass in your yard and any other nearby plants. The active component of well-known non-selective herbicides is Glyphosate. If you decide to use a non-selective herbicide weed killer, you should also apply it as you exit the sprayed area by walking backward.
You risk spreading the non-selective herbicide on your shoes and the rest of your lawn if you walk through areas where you’ve used it.
