The Grass Isn't Always Greener: Why Mixing Different Types of Grass in Your Lawn Is a Bad Idea
A well-manicured lawn is the crown jewel of many homeowners' landscapes. It's the outdoor carpet that invites you to relax, play, and bask in the beauty of your property. The allure of a lush, green lawn is undeniable, as it enhances your home's curb appeal and provides a perfect setting for outdoor activities. Achieving that emerald expanse under your feet is a testament to your dedication to lawn care.
In the quest for the perfect lawn, many homeowners may be tempted to mix different types of lawn grass to capitalize on each variety's strengths. Maybe you've heard that one grass type is more drought-tolerant while another is renowned for its lush, green appearance. This mixture, however, isn't always a guaranteed recipe for success. Mixing various grass types can lead to a host of complications and challenges that often outweigh the perceived benefits.
The Problem with Mixing Grass Types
Incompatibility of Growth Patterns
Varying growth rates: When you mix different grass types in your lawn, you're essentially blending plants with distinct growth habits. Some grasses are fast-growers, while others are slower to develop. This incongruity in growth rates can lead to uneven patches, where one type of grass outpaces the others, resulting in an aesthetically displeasing, patchy appearance.
Different mowing requirements: The dissimilarity in growth patterns also extends to mowing requirements. Some grasses thrive when kept short, while others prefer a slightly longer blade length. This divergence can make mowing a logistical headache as you attempt to accommodate the preferences of each grass type. The result? An inconsistent, unkempt lawn.
Herbicide choice complexity: Most selective herbicides are designed for use on either cool or warm-season grass. With a mixed-grass lawn, you are limited on herbicide choices that will effectively control weeds without injuring your lawn. For example, Celsius WG is an excellent broadleaf herbicide that controls over 150 weeds. While safe for most warm-season grasses, it can’t be used on a lawn composed of cool and warm-season grass without causing injury.
Pest and Disease Vulnerability
Bermuda grass and its invasive nature: One of the most notorious examples of a grass variety causing problems when mixed with others is Bermuda grass. While Bermuda is appreciated for its durability and resilience in warm climates, it is notorious for its invasive nature. It tends to encroach upon neighboring grasses, making it challenging to keep it contained within its boundaries.
Challenges of eliminating Bermuda from Zoysia or St. Augustine lawns: If you've ever tried to eradicate Bermuda grass from a Zoysia or St. Augustine lawn, you'll know that it's no small feat. Bermuda's tenacious growth habit, with its rhizomatous and stoloniferous nature, allows it to rapidly spread and infiltrate neighboring grasses. Removing it becomes an ongoing battle that requires strategic measures and patience.
Aesthetic Issues
Varied textures and colors: Different grass types come with distinct textures and shades of green. When you mix them, you'll likely notice a mismatch in the visual appeal of your lawn. This inconsistency in texture and color can create an eyesore, disrupting the visual harmony of your outdoor space.
Uneven growth and patchiness: Incompatibility in growth patterns, combined with the invasive nature of some grasses, can result in patchiness and irregular growth across your lawn. This creates an unattractive, disheveled appearance that's far from the lush, uniform carpet of green that many homeowners aspire to achieve.

The Bermuda Grass Challenge
Understanding Bermuda Grass
Characteristics and growth habits: Bermuda grass (Cynodon dactylon) is a warm-season grass that thrives in hot, sunny climates. Bermuda grass is a popular choice for lawns, golf courses, and sports fields and is known for its hardiness and resilience. It spreads through both rhizomes and stolons, allowing it to rapidly fill in open areas and recover from damage. However, these same characteristics can make Bermuda grass an invasive challenge in mixed lawns.
Why Bermuda is often unwanted in other lawns: While Bermuda grass has many qualities that make it a sought-after grass type for some homeowners, it is often unwelcome in lawns dominated by other grass varieties. Its vigorous growth and spreading tendencies can quickly overtake and smother the competing grass types, resulting in an unattractive and inconsistent lawn appearance. This is why it is important to understand the problems that may arise when Bermuda grass infiltrates other grasses.
How Bermuda Invades Other Grass Types
Bermuda grass invades other grass types primarily through its rhizomatous and stoloniferous growth. It sends underground rhizomes and above-ground stolons, creating a network that rapidly expands across your lawn. This invasive behavior allows Bermuda to outcompete and replace other grass varieties, often creating a two-toned, disruptive appearance.
Strategies for Removing Bermuda from Zoysia or St. Augustine Lawns
If you find yourself dealing with a battle between Zoysia vs Bermuda or St. Augustine grass vs. Bermuda, it's essential to take action promptly. Here are some strategies for managing and, if possible, eliminating Bermuda grass from your lawn:
Manual Removal
You can try carefully digging up and removing Bermuda grass rhizomes and stolons, but that could take quite a while, and the likelihood of getting all of Bermuda grass out is pretty slim. We’ve heard of a case where the top 8 inches of topsoil were removed in an attempt to eliminate Bermudagrass. 18 months later, it was back.
Traditional Herbicides
Traditional herbicides, like Fusilade II, are widely known but produce limited results when applied at the rates deemed safe for Zoysia lawns. The persistent nature of Bermuda grass often renders these methods ineffective in achieving the desired results, leaving homeowners frustrated in their efforts to maintain a uniform, healthy lawn.
A Game-Changing Solution: The Recognition and Fusilade II Herbicide Kit
Fortunately, a solution has emerged in the form of Syngenta's Recognition herbicide, used in combination with Fusilade II. This revolutionary herbicide will bring a sigh of relief to homeowners who have been struggling to control common or hybrid Bermudagrass while preserving their Zoysia and St. Augustine lawns.
Key Features of Recognition Herbicide:
- Broad-spectrum weed control: Recognition and Fusilade II go beyond the battle with Bermuda grass; they extend effectiveness to combat more than 85 different types of grassy, sedge, and broadleaf weeds. This comprehensive approach enables you to address multiple weed issues in a single step, streamlining your lawn maintenance.
- Sedge and Poa annua control: In addition to its Bermuda grass control, Recognition stands out as a reliable solution for managing various sedges, including nutsedge, kyllinga, annual sedges, and globe sedges. It also excels in curbing the notorious annual bluegrass, Poa annua, which can disrupt the aesthetics of your lawn.
While Bermuda grass has been a persistent problem in Zoysia and St. Augustine lawns, Syngenta's Recognition herbicide has emerged as a groundbreaking solution, offering homeowners an effective means of control. This innovative herbicide enables homeowners to enjoy the best of both worlds: a beautiful, lush lawn consisting of their preferred grass types while successfully managing Bermuda grass's invasive tendencies.

By combining the selective action of Recognition with the enhanced effectiveness of Fusilade II, this kit represents a significant leap forward in lawn care.
Frequent Mowing and Addressing Bare Patches
Mowing your lawn at the appropriate height for your desired grass type will encourage a thick lawn making it more difficult for Bermuda grass to establish. If you’ve used herbicides to eliminate Bermuda, bare areas can be filled by transferring plugs from your existing lawn or installing new sod.
Successfully managing Bermuda grass in a Zoysia or St. Augustine lawn can be a challenging and ongoing endeavor. It requires persistence and a combination of manual work, herbicide application, and strategic lawn care practices to ensure the invasive grass doesn't regain a foothold.

Grass Types That Work Well Together
Compatibility of Grass Types
Combining cool-season and warm-season grasses: An approach to harmonious grass mixing involves blending cool-season and warm-season grasses at different times of the year. This method is particularly useful in regions with varying climates. Cool-season grass that establishes quickly, like perennial ryegrass, can maintain a green lawn during cooler months.
Overseeding Bermuda with Perennial Ryegrass in the fall is a strategy some homeowners and professional turf managers use. Bermuda goes dormant in the fall which allows the Ryegrass to grow without competition. You’d get rid of the cool-season grass in spring allowing warm-season grasses like Bermuda or Zoysia to take over in the warmer seasons.
Complementary Features
Drought resistance: Combining drought-resistant grass types in your lawn can help conserve water and maintain a lush appearance even during dry periods. Grasses like Bermuda and Buffalo grass are known for their exceptional drought tolerance and can complement the water needs of other grass varieties.
Shade tolerance: In areas with varying degrees of sunlight, consider mixing grass types with varying shade tolerance. Shade-tolerant varieties like tall fescue or fine fescue or can thrive in areas with limited sun exposure, while sun-loving types can take care of the sunnier spots.
Avoiding the "patchwork quilt" effect: By selecting grass types that are compatible in terms of growth habits, you can prevent the "patchwork quilt" effect that often plagues mixed lawns. This results in a uniform, consistent appearance that enhances your lawn's overall appearance.
Lawn Care Tips for a Beautiful Lawn
A picturesque, green lawn is the result of diligent and consistent lawn care practices. It's essential to follow these lawn care tips to ensure your grass varieties thrive and maintain their lush appearance:
Soil Preparation and Maintenance
Soil testing: Before planting or renovating your lawn, conduct a soil test to determine its pH and nutrient levels. Adjusting the soil's pH and providing necessary nutrients will create an ideal environment for your chosen grass types.
Adequate aeration: Regularly aerate your lawn to alleviate soil compaction and improve the flow of air, water, and nutrients to the grassroots.
Proper soil drainage: Ensure proper drainage to prevent waterlogging, as standing water can damage grass roots and promote disease.
Proper Mowing Techniques
Appropriate mowing height: Adjust your mower to the recommended height for your chosen grass types. Mowing too short can stress the grass while mowing too tall can encourage thatch buildup.
Regular mowing: Stick to a consistent mowing schedule, removing no more than one-third of the grass blade's height at a time. This helps maintain a healthy and attractive lawn.
Sharp blades: Keep your mower blades sharp to prevent tearing and damage to the grass. Dull blades can lead to brown tips and make your lawn more susceptible to diseases.
Watering Guidelines
Deep and infrequent watering: Water your lawn deeply and infrequently to encourage deep root growth. Shallow, frequent watering can result in weak, shallow roots.
Morning watering: Water your lawn in the early morning to allow the grass to dry before evening, reducing the risk of fungal diseases.
Fertilization and Weed Control
Balanced fertilization: Apply fertilizers according to the specific needs of your grass types, focusing on nitrogen, phosphorus, and potassium (NPK) ratios. Over-fertilization can lead to excessive growth and thatch accumulation.
Weed prevention and control: Regularly inspect your lawn for weeds and implement weed control measures as needed. Use pre-emergent and post-emergent herbicides when appropriate.
Lawn care schedule: Create a lawn care schedule that outlines specific tasks and schedules for fertilization, aeration, pest control, and other essential lawn maintenance.
By implementing these lawn care tips, you can ensure the health and vibrancy of your grass types. Your lawn will not only look beautiful but will also resist the challenges that mixed grasses or invasive varieties might bring.
