    Bermuda grass, a common lawn pest, is renowned for its aggressive growth and persistence, often frustrating homeowners and gardeners alike. This perennial lawn grass, also known as “devil’s grass,” can invade lawns, flower beds, and gardens, causing various maintenance problems. Yet, as challenging as this invader might be, there are effective strategies to curb its spread and restore the beauty of your outdoors. This comprehensive guide will provide you with the tools and techniques you need to control and get rid of Bermuda grass effectively.

    Understanding the nature of Bermuda grass, identifying it correctly, and implementing efficient preventive and eradication strategies are crucial to reclaim your lawn. This guide aims to equip you with knowledge and practical tips to not only eliminate Bermuda grass but also to prevent its re-infestation. 

    Understanding Bermuda Grass

    Bermuda grass (Cynodon dactylon) is a warm-season grass originating from Africa. It is now widespread across the world, particularly in tropical and subtropical regions. Bermuda grass is characterized by its robust growth, deep root systems, and ability to withstand a range of soil conditions and climates. This versatility contributes to its popularity as a turfgrass for sports fields, golf courses, and lawns in warm climates. However, these same characteristics also make Bermuda grass a formidable weed in areas where it’s not wanted.

    The problem with Bermuda grass arises from its invasive nature. It grows rapidly, often outcompeting other grass types and plants for nutrients, water, and sunlight. Its extensive root system, which can reach depths of up to six feet, makes it incredibly resilient and difficult to eradicate. Bermuda grass spreads through both its roots (rhizomes) and horizontal shoots (stolons), quickly taking over new areas and choking out other plants.

    Bermuda grass thrives in full sun and prefers warm temperatures. While it can tolerate a variety of soil types, it grows best in well-drained, fertile soils. However, it also exhibits an admirable level of drought tolerance, enabling it to survive in less-than-optimal conditions.

    Understanding the biology and growth habits of Bermuda grass is the first step towards its effective control and management. Armed with this knowledge, you’ll be better prepared to tackle this invasive grass head-on and restore the health and aesthetic appeal of your lawn or garden.

    Identifying Bermuda Grass

    Accurate identification is a crucial first step in managing any weed, and Bermuda grass is no exception. Misidentification can lead to improper management strategies that may exacerbate the problem or harm the surrounding vegetation. Bermuda grass possesses several distinct features that can help distinguish it from other grass types.

    Bermuda grass is a perennial grass species with a deep and extensive root system. It produces both above-ground runners known as stolons and below-ground runners called rhizomes. Its leaves are flat and rough, typically 1/8 to 1/4 inch wide and 1 to 3 inches long. They’re gray-green to bluish-green in color, with a noticeable midrib and smooth margins. The leaf sheath, the part that wraps around the stem, is usually hairless. 

    The stems are slightly flattened and can grow to a height of about 4 to 12 inches. Bermuda grass produces seed heads that appear like a bird’s foot or a pitchfork, extending outward from the stem.

    When comparing Bermuda grass to other lawn grasses, look for the fast growth, the vigorous spreading habit through stolons and rhizomes, the distinctive seed head, and the ability to withstand high temperatures and dry conditions. These key features will help you differentiate Bermuda grass from other common grass types like St. Augustine grass or Zoysia grass.

    Bermuda Grass Lifecycle and Growth Habits

    Understanding the lifecycle and growth habits of Bermuda grass can provide insights into its resilience and strategies for its control. Bermuda grass is a warm-season grass, which means its period of active growth typically begins in late spring or early summer when soil temperatures reach 65 to 70 degrees Fahrenheit. The growth continues throughout the summer and slows down with the arrival of cooler fall temperatures.

    Bermuda grass spreads aggressively via its rhizomes and stolons. The stolons stretch out from the main plant and establish new plants where their nodes touch the ground. Similarly, the rhizomes extend underground, enabling the grass to penetrate deep into the soil and emerge far from the parent plant. 

    This dual system of propagation makes Bermuda grass incredibly invasive and tough to control. Even small fragments left in the soil can regrow and establish new plants, leading to reinfestation.

    Bermuda grass produces seeds during the summer. Although seed production plays a lesser role in its spread compared to the stolons and rhizomes, it is still a viable means of propagation. Once matured, the seeds can be spread by wind, water, animals, and even garden equipment, facilitating the grass’s invasion into new areas.

    With a comprehensive understanding of the biology, identification characteristics, and growth habits of Bermuda grass, you’re now ready to explore prevention and eradication strategies.

    Prevention Strategies for Bermuda Grass

    Preventing the invasion of Bermuda grass is easier and often more cost-effective than trying to eradicate it once established. Here are some effective strategies to keep Bermuda grass at bay:

    Lawn Care Practices

    Mowing your lawn at the correct height is crucial to discourage Bermuda grass. Taller grass can shade the soil, making it difficult for Bermuda grass seeds to germinate and grow. The correct mowing height varies depending on the type of grass you have in your lawn. 

    Fertilization and Watering

    Proper watering and fertilization can encourage the growth of your desired grass type, helping it compete against Bermuda grass. Overwatering or underwatering can stress your lawn, making it more susceptible to Bermuda grass invasion. Similarly, proper fertilization encourages healthy growth, which can outcompete Bermuda grass.

    Choosing the Right Grass Type

    If you live in an area prone to Bermuda grass, consider planting grass types that can effectively compete with it. These could be cool-season grasses or warm-season grasses that are better adapted to your specific location. 

    How To Get Rid of Bermuda Grass

    Natural Methods

    Even with the best preventive measures, Bermuda grass can find its way into your lawn or garden. Here are some natural methods to help you get rid of it:


    Solarization is a process that uses the sun’s energy to heat the soil, thereby killing Bermuda grass and its seeds. This method involves covering the infested area with a clear plastic sheet for several weeks during the hottest part of the year. The heat trapped under the plastic can effectively kill Bermuda grass and other weeds.

    Organic Mulching

    Mulching can be a very effective way to suppress Bermuda grass. Cover the infested area with a thick layer of organic mulch. This blocks the sunlight, inhibiting the growth of Bermuda grass. However, keep in mind that Bermuda grass is quite tenacious, and this method may require persistent efforts.

    Manual Removal

    For small patches, manual removal can be an effective approach. This involves digging out the Bermuda grass, ensuring you remove as much of the root system as possible. The key to success with manual removal is persistence and regular monitoring to prevent regrowth from any missed roots or rhizomes.

    Remember, using these natural methods requires consistency and patience. Bermuda grass is resilient, and it may take multiple attempts and a combination of different methods to effectively eradicate it.

    Using Herbicides to Control Bermuda Grass

    If natural methods are not enough or the infestation is too extensive, herbicides may be a viable option. They can be highly effective but should be used judiciously to minimize their impact on the environment and non-target plants.

    Post-emergent Herbicides

    These are applied directly to Bermuda grass after it has emerged from the soil. They are typically used during the growing season when the grass is actively absorbing nutrients. Glyphosate is a common active ingredient in many post-emergent herbicides, known for its effectiveness against Bermuda grass.

    Pre-emergent Herbicides

    These are applied to prevent Bermuda grass seeds from germinating. They create a barrier in the soil that inhibits the growth of new shoots. Pre-emergent herbicides, such as prodiamine and dithiopyr, are typically applied in early spring before soil temperatures reach the level at which Bermuda grass seeds germinate.

    Restoration of Your Lawn After Bermuda Grass Eradication

    Once you have successfully eradicated Bermuda grass, it’s time to restore your lawn. It’s crucial to act promptly to prevent Bermuda grass or other weeds from taking advantage of the bare soil.

    Restoring Your Lawn

    Begin by testing and amending your soil as needed to ensure it provides a hospitable environment for your chosen grass type. Reseed or sod the area with a grass that’s well-suited to your region and the specific conditions of your yard.

    Maintaining a Healthy, Bermuda Grass-free Lawn

    Regular mowing, proper watering, and appropriate fertilization can keep your lawn healthy and resistant to Bermuda grass invasion. Encourage dense growth to crowd out any potential Bermuda grass sprouts.

    Reseeding Your Lawn

    The best time to reseed your lawn depends on the type of grass you’re planting. For most cool-season grasses, early fall is ideal. For warm-season grasses, late spring to early summer is usually the best time. Proper care after reseeding is vital to ensure the new grass establishes well and thrives.

    Remember, patience is key when restoring a lawn. It might take a few seasons for your lawn to fully recover and flourish. Regular care and maintenance are critical to keep Bermuda grass at bay in the long term.

    Common Mistakes in Bermuda Grass Control and How to Avoid Them

    Even with the best intentions, it’s easy to make mistakes that can impede your Bermuda grass control efforts. Let’s explore some common mistakes and how to avoid them:

    Mistake #1: Inadequate identification and understanding of Bermuda grass: Misidentifying Bermuda grass or misunderstanding its growth habits can lead to ineffective control measures. Before taking action, ensure you’re dealing with Bermuda grass and familiarize yourself with its lifecycle and propagation methods.

    Mistake #2: Incorrect use of herbicides: Overuse or incorrect application of herbicides can harm non-target plants and may not effectively control Bermuda grass. Always read and follow the manufacturer’s instructions for the best results.

    Mistake #3: Failure to maintain a consistent lawn care routine: Regular lawn care practices, including appropriate watering, mowing, and fertilization, are crucial in maintaining a healthy lawn that can resist Bermuda grass invasion. Neglecting these routines can give Bermuda grass the upper hand.

    Case Study: Successful Bermuda Grass Eradication Efforts

    To further illustrate the discussed control methods, let’s look at a real-world example of successful Bermuda grass eradication:

    John, a homeowner from Texas, was struggling with a persistent Bermuda grass problem in his St. Augustine lawn. After correctly identifying the problem, he decided on a combined approach of manual removal, solarization, and selective post-emergent herbicide use.

    John regularly removed Bermuda grass patches by hand over a few weeks. During the peak summer heat, he applied the solarization method to more significant problem areas, leaving clear plastic sheeting in place for six weeks. After the solarization, he carefully applied a post-emergent herbicide to remaining patches. 

    After a season of diligent efforts, John’s lawn showed significant improvement, with St. Augustine grass thriving and Bermuda grass drastically reduced. This case demonstrates the effectiveness of a multi-method approach, patience, and persistence. It also highlights that Bermuda grass control is an ongoing process rather than a one-time fix.


    Successfully controlling and eradicating Bermuda grass is no small feat, requiring a good understanding of the grass’s characteristics, patience, and consistent efforts. From preventive measures like proper lawn care practices to control methods like solarization, manual removal, and judicious use of herbicides, you now have a suite of strategies at your disposal. 

    Remember that each lawn is unique, and what works for one might not work for another. Therefore, you may need to test different strategies or use a combination of them to find what works best for your situation. Keep in mind that maintaining a healthy, desirable lawn is an ongoing process and the best defense against Bermuda grass invasion.
