What is Carpet Grass and Why is it a Problem in Bermuda Lawns?
Carpet grass is a warm-season grass species known for its low-growing habit and dense, mat-like appearance. This grass type is often considered a weed in Bermuda lawns. It thrives in warm, humid conditions, making it particularly problematic in areas where Bermuda grass is the desired ground cover.
The University of Florida’s Institute of Food and Agricultural Sciences defines carpet grass as “a creeping grass that forms a thick mat, growing well in poorly drained soils.” This definition highlights its vigorous growth and adaptability.
Carpet grass spreads rapidly through stolons, which are horizontal stems that root at the nodes. It can outcompete Bermuda grass for resources like water and nutrients. This aggressive growth can lead to a decline in the quality of Bermuda lawns.
According to the Texas A&M AgriLife Extension, “Carpet grass often takes over areas that are shady or improperly maintained,” reinforcing the idea that it thrives under specific conditions.
Poor lawn maintenance, inadequate sunlight, and high humidity contribute to the proliferation of carpet grass. These factors create a conducive environment for its growth.
In areas with improper lawn care, carpet grass can increase dramatically, making it hard to eliminate. Research from the University of Georgia reports that approximately 30% of homeowners struggle with carpet grass infestations in their Bermuda lawns.
The invasion of carpet grass can lead to reduced biodiversity and decreased functionality of lawns. This can diminish the aesthetic appeal of residential and commercial properties.
Healthier lawns contribute to a better environment by reducing soil erosion and improving air quality. Economically, infestations can increase maintenance costs for homeowners.
Specific examples include homes in southern states that experience annual battles against carpet grass, leading to ongoing lawn care expenses.
To address this issue, experts suggest improving lawn care practices. Recommendations include regular mowing, proper fertilization, and targeted herbicide applications.
The use of pre-emergent herbicides before carpet grass emerges is a proactive measure. Implementing regular lawn maintenance, such as aeration and overseeding with Bermuda grass, can also help mitigate growth.
How Can You Identify Signs of Carpet Grass Infestation in Your Bermuda Lawn?
You can identify signs of carpet grass infestation in your Bermuda lawn by looking for specific visual and growth patterns that signify the presence of this weed.

How Can Lawn Care Practices Prevent Carpet Grass from Returning?
Lawn care practices can effectively prevent carpet grass from returning by maintaining healthy turf, monitoring soil conditions, and using appropriate control methods.
Healthy turf is crucial for preventing carpet grass invasions. A lush and dense lawn competes well with carpet grass, reducing its chances of establishment. Regular aeration improves soil structure and allows for better root penetration. Aeration studies, such as one by Throssell et al. (2018), show that improved airflow and water absorption lead to healthier grass that outcompetes weeds. Fertilizing with appropriate nutrients supports robust growth. For instance, nitrogen promotes green, leafy growth and thickens the lawn, which inhibits the growth of carpet grass.
Monitoring soil conditions is essential to maintaining turf health. Testing soil pH helps ensure that it is within the ideal range for desired grass species, generally between 6.0 and 7.0. A study by McElroy et al. (2015) suggests that optimal pH levels promote healthy root systems, thereby enhancing grass competition. Additionally, managing moisture levels prevents stress on turf that allows weeds like carpet grass to thrive. An overwatered lawn can create conditions suitable for carpet grass, whereas drought-stressed grass may struggle to compete.
Using appropriate control methods is vital for preventing carpet grass from returning. Applying pre-emergent herbicides can stop seeds from germinating. Research by Hager et al. (2017) highlights their effectiveness when applied at the right time, usually in early spring. Moreover, hand-pulling carpet grass in small patches can be an effective control strategy, especially if done before it seeds. Regular mowing at the correct height also contributes significantly. Mowing too low can stress desirable grass species and allow carpet grass a better opportunity to establish. Keeping the mower blade sharp and mowing at a height that maintains preferred turf thickens helps crowd out the carpet grass.
By implementing these lawn care practices, homeowners can not only suppress carpet grass but also promote a healthier and more resilient lawn.
