We’ll look at different ways to get rid of it, from simple, natural methods to more effective chemical solutions. Whether you’re a seasoned gardener or just starting out, you’ll find helpful tips and tricks to reclaim your outdoor space from this persistent invader. Let’s get started!
Understanding Your Enemy: Bermuda Grass Basics
Before we jump into how to get rid of Bermuda grass, it’s important to understand what makes it tick. This knowledge will help you choose the most effective removal method and prevent it from coming back.
- What is Bermuda grass? Bermuda grass is a warm-season grass known for its rapid growth and tough nature.1 It spreads through rhizomes (underground stems) and stolons (above-ground stems), making it quick to colonize new areas.2
- Why is it so tough to control? Those rhizomes and stolons are the key to Bermuda grass’s resilience. They form a dense network that allows the grass to survive drought, heat, and even foot traffic. Plus, even a small piece of rhizome left in the soil can sprout a whole new plant.
- Where does it thrive? Bermuda grass loves sunny spots and warm temperatures.3 It’s common in southern states and thrives in areas with sandy or clay soil.4
How to Get Rid of Bermuda Grass Naturally
If you prefer to avoid chemicals, there are several natural methods you can try to eliminate Bermuda grass:
Solarization
- How it works: Solarization uses the sun’s power to bake the soil and kill Bermuda grass and its roots.5
- Steps:
- Water the area thoroughly.
- Cover the area with a clear plastic tarp, securing the edges with rocks or stakes.
- Leave the tarp in place for 4-6 weeks during the hottest part of the year. The heat trapped under the plastic will raise soil temperatures and kill the grass.
- Pros: Environmentally friendly, no chemicals needed.
- Cons: Takes time, may not be effective for deep-rooted infestations.
Smothering
- How it works: Depriving Bermuda grass of sunlight will weaken and eventually kill it.
- Steps:
- Cover the affected area with a thick layer of mulch (cardboard, newspaper, or wood chips) to block sunlight.
- Overlap the edges of the material to prevent the grass from escaping.
- Maintain the mulch layer for several months.
- Pros: Simple, uses readily available materials.
- Cons: Can take a long time, may not be suitable for large areas.
Manual Removal
- How it works: Digging out Bermuda grass by hand is labor-intensive but can be effective for small patches.6
- Steps:
- Use a shovel or garden fork to dig out the grass, making sure to remove all the roots.
- Dispose of the grass carefully to prevent it from spreading.
- Monitor the area for regrowth and repeat the process as needed.
- Pros: No chemicals, gives you a sense of accomplishment (and a workout!).
- Cons: Time-consuming, can be difficult to remove all the roots, may not be practical for large areas.
| Method | Pros | Cons |
|---|---|---|
| Solarization | Environmentally friendly, no chemicals | Takes time, may not be fully effective |
| Smothering | Simple, uses readily available materials | Can take a long time, may not be suitable for large areas |
| Manual Removal | No chemicals, good for small areas | Time-consuming, can be difficult to remove all roots |
How to Get Rid of Bermuda Grass with Herbicides
For larger infestations or more stubborn Bermuda grass, herbicides may be the most effective solution. Always follow the instructions on the herbicide label carefully and wear appropriate protective gear.
Non-Selective Herbicides
- How they work: These herbicides kill any plant they come into contact with, including Bermuda grass.
- Active ingredients to look for: Glyphosate (e.g., Roundup)
- Application: Apply the herbicide directly to the Bermuda grass, avoiding contact with desirable plants.
- Pros: Effective at killing the entire plant, including the roots. | Cons: Can harm other plants, may require repeated applications.
Selective Herbicides
- How they work: These herbicides target specific types of grasses, like Bermuda grass, while leaving other plants unharmed.7
- Active ingredients to look for: Sethoxydim, Fluazifop
- Application: Apply the herbicide according to the label instructions, usually when the Bermuda grass is actively growing.
- Pros: Can be used to control Bermuda grass in lawns or near desirable plants.
- Cons: May require repeated applications, may not be effective against all types of Bermuda grass.
| Herbicide Type | Active Ingredients | Pros | Cons |
|---|---|---|---|
| Non-Selective | Glyphosate | Effective, kills entire plant | Can harm other plants, may require reapplication |
| Selective | Sethoxydim, Fluazifop | Targets Bermuda grass, safer for other plants | May require reapplication, may not be fully effective |
Important Considerations When Using Herbicides:
- Timing: Apply herbicides when Bermuda grass is actively growing for best results.
- Safety: Wear gloves, protective clothing, and eye protection when handling herbicides.
- Environmental impact: Choose herbicides that are less harmful to the environment and follow label instructions carefully.
Preventing Bermuda Grass from Coming Back
Once you’ve successfully gotten rid of Bermuda grass, you’ll want to take steps to prevent it from returning:
- Maintain a healthy lawn: A thick, healthy lawn will help crowd out Bermuda grass and make it harder for it to take root.8
- Mulch bare spots: A layer of mulch in garden beds will suppress weed growth, including Bermuda grass.9
- Edge your lawn: Create a clear boundary between your lawn and garden beds to prevent Bermuda grass from spreading.
- Clean your garden tools: Bermuda grass can spread through rhizomes clinging to tools. Clean your tools after working in infested areas.
- Monitor for regrowth: Regularly inspect your lawn and garden for signs of Bermuda grass and take action immediately if you see it.
How to Get Rid of Bermuda Grass in Specific Areas
- Smothering: Use cardboard or newspaper to cover the affected area.
- Manual removal: Carefully dig out the grass, ensuring you remove all the roots.
- Herbicides: Use a selective herbicide to target the Bermuda grass without harming your flowers.
How to Get Rid of Bermuda Grass in Vegetable Gardens
- Solarization: Cover the garden bed with clear plastic during the hottest months.
- Mulching: Use a thick layer of organic mulch, such as straw or wood chips, to suppress the grass.
- Hand weeding: Regularly pull out any Bermuda grass seedlings you see.
How to Get Rid of Bermuda Grass in Lawns
- Selective herbicides: Apply a herbicide specifically designed to kill Bermuda grass without harming your desired lawn grass.
- Sod removal: For severe infestations, you may need to remove the existing sod and replant with a new lawn.
Summary
Getting rid of Bermuda grass can be a challenge, but with persistence and the right approach, you can succeed. Natural methods like solarization and smothering are environmentally friendly options, while herbicides offer a more efficient solution for larger infestations. Remember to choose the method that best suits your needs and always follow safety instructions.
By understanding the growth habits of Bermuda grass and implementing preventive measures, you can keep this persistent weed at bay and enjoy a beautiful, thriving lawn and garden.
FAQs
Can vinegar kill Bermuda grass?
While vinegar can kill the top growth of Bermuda grass, it’s unlikely to eliminate the roots. Repeated applications may be necessary, but it’s not a guaranteed solution.
What is the best time of year to get rid of Bermuda grass?
The best time to control Bermuda grass is during its active growing season, which is typically in the spring and summer. This is when herbicides are most effective.
Is there a way to prevent Bermuda grass from spreading to my neighbor’s yard?
Create a clear barrier, such as a trench filled with gravel or a physical edging, to prevent rhizomes from spreading to your neighbor’s property.
Will mowing help get rid of Bermuda grass?
While frequent mowing can help weaken Bermuda grass, it won’t eliminate it completely. The roots will remain and the grass will continue to grow.
Can I use boiling water to kill Bermuda grass?
Yes, pouring boiling water on Bermuda grass can kill it, but it may also harm surrounding plants and needs to be repeated consistently.
