Pour éliminer le gazon de Bermuda, utilisez un herbicide à base de glyphosate pour une solution rapide et efficace. La chaleur extrême et le désherbage manuel peuvent également faire leur travail, mais cela demande plus de patience. La clé est de cibler et de supprimer complètement le Bermuda pour éviter qu’il ne repousse.
Pour tuer le Bermuda grass, l’herbicide glyphosate est souvent la méthode la plus efficace. La chaleur intense peut aussi le brûler, mais cela prend du temps et nécessite des températures très élevées ou du feu contrôlé. La suppression manuelle implique de bêcher ou d’arracher les touffes, mais cela ne garantit pas une élimination totale. Dans cet article, découvrez comment choisir la meilleure méthode pour éradiquer ce gazon tenace, et les conseils pour prévenir sa réapparition afin d’obtenir une pelouse uniforme et saine.
What Will Kill Bermuda Grass?
Bermuda grass is a popular choice for lawns because it stays green and looks lush during warm months. However, sometimes homeowners need to remove it so they can plant something new or fix damaged areas. Knowing what can kill Bermuda grass helps you decide the best way to do it without harming other plants.
Understanding Bermuda Grass and Its Resilience
Bermuda grass is a tough, warm-season grass that spreads quickly using both roots and runners. This grass is very hardy and often resists many common weed killers. Because of its resilience, removing Bermuda grass takes some planning and persistence. Understanding how it grows and survives helps you pick the right method to kill it effectively.
Natural Methods to Kill Bermuda Grass
Many people prefer natural ways to remove Bermuda grass without harmful chemicals. These methods might take longer but are safer for your family and environment.
Solarization with Plastic Covers
Covering Bermuda grass with heavy black plastic traps heat from the sun. This heat can kill the grass and roots over several weeks. You need to:
- Clear the area of debris
- Lay down thick black plastic sheeting
- Secure the edges to prevent heat escape
- Leave the plastic in place for 4 to 6 weeks during hot weather
This method works best in sunny, hot climates and helps reduce the grass’s root system naturally.
Applying Organic Mulches
Using thick layers of organic mulch like wood chips can smother Bermuda grass over time. The mulch prevents sunlight from reaching the grass, slowly killing it. This process might take a few months but is eco-friendly and safe.
Manual Removal and Digging
Regularly digging out Bermuda grass using a shovel or garden fork can help control its spread. Consistent removal of runners and roots prevents regrowth. This method works well for small patches and requires patience and effort.
Chemical Solutions to Kill Bermuda Grass
Chemicals can be very effective in removing Bermuda grass quickly. However, choosing the right herbicide and applying it carefully is crucial.
Using Non-Selective Herbicides
Non-selective herbicides like glyphosate are designed to kill all plants they contact, including Bermuda grass. To use:
- Apply on a dry, calm day to avoid drift
- Use a sprayer to target only the Bermuda grass
- Follow manufacturer instructions for safety and effectiveness
Be cautious, as these herbicides will also kill nearby plants if not applied carefully, so protect other vegetation.
Selective Herbicides for Bermuda Grass
Some herbicides target specific grasses and weeds while leaving most other plants unharmed. These are less common but can be useful if Bermuda grass is mixed with desirable plants. Always read labels carefully and choose products compatible with your existing lawn.
How to Effectively Use Herbicides for Bermuda Grass
Applying herbicides correctly improves their success and prevents damage to your landscape.
Timing the Application
The best time to spray herbicides is late summer or early fall when Bermuda grass is actively growing. Application during dormancy is less effective.
Preparation and Application Tips
- Mix the herbicide thoroughly according to instructions
- Spray during dry, windless days
- Use a pump or backpack sprayer for even coverage
- Reapply if necessary after a few weeks
Proper timing and precise application increase killing efficiency.
Additional Tips for Killing Bermuda Grass
Apart from methods discussed, consider these strategies for complete removal.
Consistency Is Key
Repeated treatments, whether natural or chemical, are essential for thorough Bermuda grass removal. Don’t expect instant results; patience leads to success.
Combine Methods for Better Results
Using solarization plus herbicides or manual removal with chemical treatments often produces the best outcome. Combining methods targets different parts of the grass system.
Preparing Your Soil for New Plants
After Bermuda grass is gone, amend your soil and prepare it for new grass, flowers, or vegetables. Proper preparation guarantees better growth and prevents Bermuda grass from returning.
Related Topics to Consider
Preventing Bermuda Grass Return
Applying a thick layer of mulch or installing a weed barrier fabric can prevent Bermuda grass from coming back.
Choosing Alternative Lawns
If Bermuda grass is too difficult to control, consider planting cool-season grasses or ground covers that are easier to maintain.
Professional Lawn Removal Services
For large areas or tough cases, hiring professionals ensures complete removal using advanced equipment and proven techniques. This option is faster but may cost more.
Environmental Impact and Safety
Always weigh the environmental effects of chemical herbicides. Use non-chemical methods when possible and follow safety guidelines to protect your family, pets, and nearby plants.
Cost and Time Investment
Consider the resources needed for each method, including time, money, and effort. Natural methods may need months, while chemicals can work in weeks but require careful handling.
By understanding what can kill Bermuda grass and how to apply these techniques properly, you can reclaim your lawn and create the outdoor space you want. Whether you choose natural or chemical options, consistency and patience will lead to the best results.

Frequently Asked Questions
What chemical options are effective for eliminating Bermuda grass?
Herbicides containing glyphosate or selective post-emergent herbicides can effectively kill Bermuda grass. Applying these chemicals during active growth periods ensures better absorption and results. Always follow the manufacturer’s instructions and consider spot treating to minimize impact on surrounding plants.
How does soil treatment help in killing Bermuda grass?
Adjusting soil conditions by lowering soil pH or removing the rhizomes can weaken Bermuda grass. Solarization, which involves covering the area with clear plastic during hot weather, heats the soil and destroys the grass’s roots. Consistent soil treatment can significantly reduce Bermuda grass presence.
Can physical removal methods effectively eradicate Bermuda grass?
Yes, digging out Bermuda grass, including its rhizomes and stolons, can help control its spread. However, this process requires continuous effort, as any remaining underground parts may sprout anew. Combining physical removal with other methods enhances overall effectiveness.
Are there natural or organic ways to control Bermuda grass?
Applying thick mulch layers can suppress Bermuda grass growth by blocking sunlight. Additionally, smothering it with newspaper or cardboard can be effective temporarily. Regular manual removal combined with these methods helps reduce Bermuda grass without chemicals.
What maintenance practices prevent Bermuda grass from returning after removal?
Maintaining a healthy, dense turf with proper watering, fertilization, and mowing can prevent Bermuda grass from re-establishing. Regularly auditing your lawn and promptly removing any new growth helps keep Bermuda grass at bay effectively.
Final Thoughts
What will kill Bermuda grass? Strong herbicides like glyphosate effectively eliminate it, especially when applied correctly. Manual removal by digging out roots also helps, but it requires effort and persistence. For stubborn patches, combine herbicide use with proper lawn care practices to prevent regrowth. Ultimately, understanding the causes and applying targeted treatments ensures Bermuda grass does not takeover your lawn.
