Yes, glyphosate can kill Bermuda grass, but it’s not always the most effective or selective method. It’s a powerful herbicide that targets a wide range of grasses and weeds, including Bermuda, so use it carefully if you want to eliminate Bermuda grass without harming other plants.
Glyphosate will generally kill Bermuda grass if applied directly, but it can also affect surrounding plants if not used precisely. For those looking to remove Bermuda grass quickly and effectively, glyphosate offers a solution; however, it may require multiple applications for complete eradication and can harm desirable vegetation nearby. Understanding how this chemical works and its proper application can help you decide whether glyphosate is the right choice for your lawn or landscape. In this article, we’ll explore how glyphosate interacts with Bermuda grass, best practices for application, and alternative methods to consider for weed control.
Does Glyphosate Kill Bermuda Grass? An In-Depth Look
Many homeowners and landscapers wonder whether glyphosate is effective at killing Bermuda grass. This question is common because Bermuda grass is known for its resilience and fast growth. Understanding how glyphosate interacts with Bermuda grass can help you decide the best weed control methods.
What Is Glyphosate?
Glyphosate is a popular herbicide used to eliminate weeds and unwanted plants. It works by blocking an enzyme essential for plant growth. Since this enzyme is absent in animals, glyphosate is considered relatively safe for humans when used properly.
It is a non-selective herbicide, meaning it can kill most plants it contacts. That makes it very effective against a wide range of weeds but also requires careful application to avoid damaging desirable grasses like Bermuda.
How Does Glyphosate Work on Bermuda Grass?
Glyphosate targets the plant’s ability to produce certain amino acids necessary for growth. When applied to Bermuda grass, it is absorbed through the leaves and transported throughout the plant. This process eventually kills the entire plant, including roots.
However, Bermuda grass’s vigorous root system can sometimes make it resistant to partial treatments. The effectiveness of glyphosate depends on factors like application timing, concentration, and the health of the Bermuda grass.
Is Glyphosate an Effective Solution for Killing Bermuda Grass?
In most cases, glyphosate can kill Bermuda grass when used correctly. It is especially useful for spot treatment or when removing Bermuda from specific areas. But because Bermuda is hardy, multiple applications may be necessary.
It is important to note that glyphosate may take several days to weeks to fully kill Bermuda grass. Patience and proper application are key to success.
Factors That Affect Glyphosate’s Effectiveness on Bermuda Grass
Timing of Application
The best time to apply glyphosate is when Bermuda grass is actively growing, typically during late spring and summer. Applying during dormancy or when the grass is stressed may reduce effectiveness.
Concentration and Dosage
Using the proper concentration is crucial. A higher concentration can improve kill rates but may increase the risk of damaging surrounding plants. Always follow manufacturer instructions for dilution.
Application Technique
Ensure thorough coverage of the leaves for maximum absorption. Use a spray nozzle that provides even distribution. Avoid overspray onto desirable plants or turf areas where you do not want to kill the grass.
Weather Conditions
Applying glyphosate during dry, windless days enhances effectiveness. Rain shortly after application can wash away the herbicide and reduce its impact.
Will Glyphosate Kill Bermuda Grass Roots?
Yes, glyphosate can reach and kill Bermuda grass roots if applied properly. It is transported through the plant to the roots, causing the entire plant to die. Multiple applications may be necessary to ensure complete root elimination.
Deep roots can sometimes survive initial treatments, so monitor the area and reapply if new growth appears.
How to Use Glyphosate Safely and Effectively on Bermuda Grass
- Wear protective gear: gloves, goggles, and long sleeves to prevent skin contact.
- Apply on a calm day: avoid windy conditions to prevent drift onto other plants.
- Use targeted spraying: apply only to Bermuda grass areas to avoid damaging other plants.
- Follow label instructions: use recommended concentrations and application methods.
- Repeat treatments: be prepared for multiple applications for complete eradication.
Alternatives to Glyphosate for Killing Bermuda Grass
Non-Chemical Methods
- Manual removal: dig out Bermuda grass using shovels and tools.
- Smothering: cover the grass with black plastic or cardboard to block sunlight.
- Heat treatment: use a propane torch or steam to kill grass patches.
Other Chemical Options
- Other herbicides: products containing MSMA or sethoxydim may be effective but check local regulations.
- Selective herbicides: certain products target Bermuda grass specifically without harming other grasses.
Preventing Bermuda Grass Regrowth
After killing Bermuda grass, maintaining a healthy lawn can prevent its return. Regular mowing, proper fertilization, and overseeding with desired grasses help suppress Bermuda. Avoid overwatering or leaving bare patches where Bermuda can re-establish.
Environmental Considerations and Safety Tips
Glyphosate’s impact on surrounding plants and water sources should not be overlooked. Always apply it carefully and avoid runoff into waterways. Store herbicides safely, out of reach of children and pets.
Follow local regulations regarding herbicide use to protect the environment and comply with laws.
Summary of Key Points
| Factor | Impact on Bermuda Grass |
|---|---|
| Application Timing | Best during active growth seasons |
| Concentration | Proper dosing increases effectiveness |
| Weather Conditions | Dry, calm days are ideal |
| Number of Treatments | Multiple applications often needed |
While glyphosate can kill Bermuda grass effectively when applied properly, it requires patience and careful execution. Combining chemical treatments with manual and cultural controls offers the best chance for complete eradication. Always prioritize safety and environmental considerations during the process to protect your lawn and surrounding areas.

Frequently Asked Questions
Will glyphosate effectively eliminate bermuda grass?
Glyphosate can kill bermuda grass if applied directly and thoroughly. It works by targeting the plant’s entire system, so applying it properly over the affected area will typically result in effective removal. However, bermuda grass is resilient and may require multiple treatments for complete eradication.
How long does it take for glyphosate to show results on bermuda grass?
After applying glyphosate to bermuda grass, you may start to see signs of the grass dying within a few days. Full results often become visible within one to two weeks. Patience is essential, as multiple applications might be necessary for total removal.
Can I use glyphosate on bermuda grass without harming nearby plants?
Glyphosate is a non-selective herbicide, so it can affect surrounding plants if it comes into contact with them. To protect other vegetation, apply glyphosate carefully using spot treatments or barrier methods to avoid overspray. Always follow the manufacturer’s instructions to reduce unintended damage.
Does weather influence the effectiveness of glyphosate on bermuda grass?
Yes, weather conditions impact glyphosate’s performance. Cooler, dry days with low wind are ideal for application. Rain can wash away the herbicide before it absorbs or cause runoff, reducing its effectiveness. Wait for suitable weather to ensure the best results.
Is there a risk of bermuda grass regrowing after glyphosate treatment?
Bermuda grass may regrow if roots are not fully killed or if the herbicide was applied selectively. Follow-up treatments and proper application techniques help prevent regrowth. Combining glyphosate with other control methods can also improve long-term management.
Final Thoughts
Glyphosate can effectively kill bermuda grass, especially when used correctly. However, it may require multiple applications to completely eradicate stubborn patches. Always follow the manufacturer’s instructions for safe and effective results.
In conclusion, does glyphosate kill bermuda grass? Yes, it does. Proper application is key to ensuring complete removal without damaging surrounding plants.
