St. Augustine vs. Bermuda Grass

St. Augustine vs. Bermuda Grass – Choosing the right type of grass for your lawn is a decision that every Texas homeowner will face at some point. It’s a critical decision that can impact not only the aesthetics of your outdoor space but also the time and resources you’ll need to maintain it. In the Lone Star State, two types of grass are perennial favorites: St. Augustine and Bermuda. 

Both have their unique sets of advantages and disadvantages, making it a truly tough call. In this blog, we’ll dive deep into the world of St. Augustine vs. Bermuda grass, dissecting their characteristics, maintenance requirements, and suitability for the Texas climate. We’ll provide you with the insights you need to make an informed decision for your green oasis. So, let’s get started and find out which of these grass types is truly the best for your Texas lawn.

Key Characteristics and Growth Habits of St. Augustine Grass

St. Augustine grass, scientifically known as Stenotaphrum secundatum, is a warm-season grass native to the Gulf Coast region. It has a distinct shade tolerance that makes it a popular choice among homeowners in Texas, particularly those with lawns receiving partial sunlight. Let’s delve into the key characteristics and growth habits of St. Augustine grass.

  • Appearance: St. Augustine grass exhibits a dark green hue and has wide, flat leaf blades that create a thick, carpet-like appearance when properly maintained. The dense coverage prevents weed growth and is visually appealing, making it an ideal choice for many Texas homeowners.
  • Shade Tolerance: One of the primary reasons why St. Augustine grass is so popular is its ability to thrive in both sunny and moderately shaded areas. It requires at least 4-6 hours of sunlight per day but can adapt well to partial shade, making it suitable for diverse landscaping situations.
  • Growth Rate: St. Augustine grass is known for its aggressive growth, which can be advantageous for covering bare spots and filling in the lawn quickly. However, this fast growth rate also means that it might require more frequent mowing during the peak growing season.
  • Drought Tolerance: St. Augustine grass has moderate drought tolerance, although it displays consistent performance during brief dry periods. Regular watering helps maintain its lush appearance and prevent it from entering dormancy during extended droughts.

Pros and Cons of Using St. Augustine Grass in Texas

St. Augustine grass offers several benefits to Texas homeowners but also comes with its share of challenges. Here’s an overview of the pros and cons associated with this grass type:


1. Excellent Shade Tolerance: St. Augustine grass can thrive in areas with partial shade, making it a versatile choice for homeowners with diverse sun exposure in their yards.

2. Dense Coverage: The thick growth of St. Augustine grass creates an appealing, carpet-like appearance, and helps suppress weed growth.

3. Rapid Establishment: St. Augustine grass grows quickly, filling in bare spots and creating a thick lawn within a relatively short period.


1. Higher Maintenance: The fast growth rate of St. Augustine grass can lead to more frequent mowing and watering requirements compared to other grass types.

2. Susceptibility to Pests and Diseases: St. Augustine grass is prone to pests such as chinch bugs, grubs, and diseases like brown patch and gray leaf spot, necessitating proactive pest control measures.

3. Cold Sensitivity: This grass type is sensitive to extreme cold and may suffer damage during unusually harsh winters.

Key Characteristics and Growth Habits of Bermuda Grass

Bermuda grass (Cynodon dactylon) is another popular warm-season grass native to Africa and grown extensively throughout the southern United States, including Texas. Known for its drought and heat tolerance, Bermuda grass is well-suited to the region’s climate, making it a go-to choice for many homeowners. Let’s explore its key characteristics and growth habits.

  • Appearance: Bermuda grass is characterized by its fine-textured, dark green blades that form a dense, low-growing turf. Homeowners appreciate its uniform look, and it is often used on athletic fields and golf courses due to its wear resistance.
  • Sunlight Requirements: Unlike St. Augustine grass, Bermuda grass requires a substantial amount of direct sunlight—at least 6-8 hours per day—to flourish. It does not fare well under shade, which is a critical consideration when selecting grass types for your lawn.
  • Growth Rate: Bermuda grass boasts a fast growth rate and spreads quickly through both above-ground runners (stolons) and below-ground stems (rhizomes). This trait enables it to fill in bare spots and recover from wear and tear with ease.
  • Drought Tolerance: One of the most impressive features of Bermuda grass is its excellent drought tolerance. When faced with restricted water intake, it enters a state of dormancy to conserve water, and its deep root system allows it to bounce back once water supply is restored.

Pros and Cons of Using Bermuda Grass in Texas

Much like St. Augustine grass, Bermuda grass presents unique advantages and challenges for Texas homeowners. Weighing these pros and cons will help in determining if Bermuda grass is the right fit for your lawn:


1. Excellent Heat and Drought Tolerance: Bermuda grass is well-adapted to the Texas heat and can withstand periods of drought without significant damage.

2. Rapid Growth and Recovery Rate: Its aggressive growth allows for quick establishment and recovery from wear and tear.

3. Low Maintenance: Bermuda grass can tolerate lower mowing heights and requires less frequent watering compared to St. Augustine grass.


1. Lack of Shade Tolerance: Bermuda grass is unable to flourish in shaded areas, posing a problem for homeowners with limited sunlight coverage in their yards.

2. Invasive Growth: The aggressive growth of Bermuda grass can sometimes encroach on flower beds, gardens, or other grass types in your lawn.

3. Winter Dormancy: Bermuda grass turns brown during the winter months and enters a state of dormancy, losing its visual appeal until the arrival of warmer temperatures.

Maintenance Requirements for St. Augustine and Bermuda Grass

Lawn maintenance is a crucial factor to consider in choosing the right grass type for your Texas lawn. While both St. Augustine and Bermuda grass require care, their specific needs differ, impacting your routine lawn care practices.

  • Watering: St. Augustine grass requires more frequent watering than Bermuda grass, especially during extended dry periods. In contrast, Bermuda grass is known for its deeper root system and excellent drought tolerance, which enable it to withstand water restrictions and dry spells more effectively.
  • Mowing: St. Augustine grass should be mowed to a height of approximately 3 to 4 inches, while Bermuda grass can be maintained at a lower height of 1 to 2 inches. The faster growth rate of St. Augustine grass may necessitate more frequent mowing sessions during the peak growing season compared to Bermuda grass.

Fertilization and Soil Requirements for St. Augustine and Bermuda Grass

Both St. Augustine and Bermuda grass types have distinct fertilization and soil requirements that play a crucial role in their overall health and appearance. Knowing their specific needs will help you make informed decisions on their overall maintenance.

  • Fertilization: St. Augustine grass has a high need for nitrogen, requiring approximately 4-5 pounds of nitrogen per 1,000 square feet per year, with applications during the growing season. In contrast, Bermuda grass requires slightly less nitrogen, at about 2-4 pounds per 1,000 square feet annually. It’s essential to follow a carefully planned fertilization schedule for each grass type to ensure optimal nutrient absorption and avoid problems like fertilizer burn or increased susceptibility to disease.
  • Soil: Both St. Augustine and Bermuda grass types prefer well-draining soil, but Bermuda grass is more adaptive to a wider range of soil types, including clay and sandy soils. For optimal growth, St. Augustine grass prefers a slightly acidic soil with a pH between 5.0 and 7.0, while Bermuda grass can tolerate a broader pH range between 4.5 and 8.5.

Pest and Disease Management for St. Augustine and Bermuda Grass

Keeping pests and diseases at bay is essential to maintaining a healthy, vibrant lawn. Both St. Augustine and Bermuda grass can fall prey to pests and diseases, and understanding their vulnerabilities will help you implement effective preventative and curative strategies.

  • St. Augustine Grass: Common pests that target St. Augustine grass include chinch bugs, grubs, and sod webworms. They can cause considerable damage if left unchecked, so it’s crucial to monitor your lawn and act quickly to control any infestations. Diseases such as brown patch, gray leaf spot, and take-all root rot can also plague St. Augustine grass. A combination of proper lawn care practices and professional pest control measures helps keep these threats under control.
  • Bermuda Grass: While Bermuda grass is generally more resistant to diseases and pests, it’s not impervious. Armyworms and grubs can cause damage, especially during drought conditions. Diseases like spring dead spot, dollar spot, and leaf spot can also affect Bermuda grass. Integrating preventive measures such as proper irrigation, mowing, and fertilization can reduce disease incidence and ensure lasting lawn health.

Making the Right Choice for Your Texas Lawn

The decision between St. Augustine and Bermuda grass ultimately comes down to your specific lawn care goals and circumstances. Consider the following factors to identify the most suitable grass type for your Texas lawn:

  • Sunlight Exposure: St. Augustine grass is well-adapted to moderately shaded areas, while Bermuda grass requires full sun for optimal growth. Take note of your lawn’s sun exposure to make an informed decision.
  • Maintenance Requirements: Both grass types require maintenance, but St. Augustine grass generally has higher watering and mowing needs compared to Bermuda grass, which is more drought-tolerant and can thrive on less frequent irrigation and mowing.
  • Pest and Disease Susceptibility: St. Augustine grass tends to be more susceptible to pest and disease issues than Bermuda grass. If you’re looking for a more disease-resistant grass type, Bermuda grass might be a better choice.
  • Aesthetics and Functionality: Consider the visual appeal and functionality of each grass type when making your decision. St. Augustine grass widely appeals for its dense, carpet-like appearance, while Bermuda grass is known for its uniform look and wear resistance.

Preparing Your Lawn for the Chosen Grass Type

Once you’ve made your decision between St. Augustine and Bermuda grass, proper lawn preparation is essential for successful establishment. Remove any unwanted weeds, vegetation, or debris from your lawn area, and till the soil to a depth of 2-4 inches. If necessary, incorporate soil amendments such as compost or livestock manure to improve soil fertility, tilth, and drainage.

For St. Augustine grass, lay sod or use plugs spaced 12-18 inches apart for a healthy, dense coverage. Bermuda grass can be established through both sodding and seeding, depending on your preference and budget. Ensure proper watering of the new grass, following guidelines specific to your chosen grass type, and avoid walking on the lawn area during the establishment period.

Seasonal Maintenance Tips for St. Augustine and Bermuda Grass

Proper seasonal care is vital for maintaining the health and aesthetics of your St. Augustine or Bermuda grass lawn. By following appropriate maintenance practices and adjusting your lawn care routine according to the changing seasons, you can ensure a thriving and visually appealing lawn throughout the year.

Spring Lawn Care

The arrival of spring signifies a period of active growth for both St. Augustine and Bermuda grass. Here are some essential spring lawn care tips for each grass type:

St. Augustine Grass:

1. Mowing: Resume regular mowing, maintaining a height of 3-4 inches. Avoid cutting more than one-third of the grass blade at a time to prevent shock to the grass.

2. Fertilization: Apply a slow-release fertilizer based on your lawn’s specific requirements, starting in late March or early April. Take care not to over-fertilize, as this can lead to increased disease susceptibility.

3. Irrigation: Ensure adequate watering, typically 1-1.5 inches of water per week through a combination of rainfall and supplemental irrigation.

Bermuda Grass:

1. Mowing: Begin mowing Bermuda grass in spring, maintaining a height of 1-2 inches. Frequent mowing promotes horizontal growth, resulting in a denser, more uniform appearance.

2. Fertilization: Apply the first round of fertilizer once your lawn turns green and is actively growing, typically in late April or early May. Use a slow-release fertilizer in accordance with your lawn’s needs.

3. Irrigation: Increase watering frequency and volume to support active growth, providing approximately 1-1.25 inches of water per week.

Summer Lawn Care

Summer’s high temperatures can put St. Augustine and Bermuda grass under stress. Adopt proper maintenance practices to help your lawn withstand the heat and maintain a lush, vibrant appearance:

St. Augustine Grass:

1. Mowing: Continue mowing at the recommended height of 3-4 inches, and always mow in the early morning or evening to reduce heat stress.

2. Fertilization: Avoid heavy fertilization during the summer months, as this can lead to lawn burn or heightened disease and pest risks.

3. Irrigation: Increase watering frequency to compensate for increased evaporation, aiming for 1.5-2 inches of water per week.

Bermuda Grass:

1. Mowing: Maintain the 1-2-inch mowing height during the summer months.

2. Fertilization: Apply a light application of slow-release fertilizer if needed, but avoid over-fertilization to prevent potential stress or damage.

3. Irrigation: Continue watering at a rate of 1-1.25 inches per week, adjusting based on local rainfall and temperature conditions.

Fall Lawn Care

As temperatures begin to drop in the fall, it’s crucial to prepare your lawn for the upcoming winter months:

St. Augustine Grass:

1. Mowing: Continue mowing at a height of 3-4 inches until growth slows or stops.

2. Fertilization: Apply a final round of fertilizer in early to mid-October to provide essential nutrients for winter dormancy and promote early spring green-up.

3. Irrigation: Gradually reduce watering frequency as temperatures drop and grass growth slows.

Bermuda Grass:

1. Mowing: Maintain the 1-2-inch mowing height until grass enters dormancy and stops growing.

2. Fertilization: Apply a final fertilization approximately six weeks before the first expected frost to promote healthy growth the following spring.

3. Irrigation: Reduce watering frequency as temperatures decline and grass growth slows.

Winter Lawn Care

During winter, both St. Augustine and Bermuda grass enter a state of dormancy. By following proper winter care practices, you can protect your lawn throughout the colder months:

St. Augustine Grass:

1. Mowing: Suspend mowing during winter dormancy.

2. Fertilization: Avoid fertilization during the winter months to prevent stimulating premature growth.

3. Irrigation: Water only when necessary to prevent excessive dryness, as overwatering can result in shallow root systems and increased winter damage.

Bermuda Grass:

1. Mowing: Cease mowing efforts during dormancy.

2. Fertilization: Refrain from fertilizing Bermuda grass during the winter months.

3. Irrigation: Water sparingly to maintain adequate moisture levels without promoting growth.

Thatch Management and Aeration for St. Augustine and Bermuda Grass

Both St. Augustine and Bermuda grass can accumulate thatch – a layer of partially decomposed grass clippings, roots, and other organic matter. Excessive thatch can suffocate your lawn, impede water and nutrient penetration, and encourage pest and disease issues. Regular dethatching and aeration are essential for maintaining a healthy lawn:

St. Augustine Grass:

1. Dethatching: Use a dethatching rake or machine for lawns with thatch layers exceeding 0.5 inches in thickness.

2. Aeration: Aerating your lawn every 2-3 years helps to break up soil compaction, allowing water, air, and nutrients to reach the grass roots.

Bermuda Grass:

1. Dethatching: Bermuda grass is more prone to thatch buildup due to its aggressive growth. Regular dethatching is necessary when the thatch layer exceeds 0.5 inches.

2. Aeration: Because of its rapid growth and susceptibility to soil compaction, Bermuda grass benefits from annual aeration, typically in the spring or early summer.

By implementing customized care, including proper mowing, fertilization, irrigation, pest and disease management, and seasonal maintenance, your St. Augustine or Bermuda grass lawn can thrive in Texas’s unique climate. Moreover, using professional lawn care services such as Real Green ensures that your chosen grass type receives the expert care and attention it needs to stay healthy and vibrant year-round.
