The Unique Benefits of Growing Coastal Bermuda Grass
When you think of a resilient, sun-loving pasture or a durable lawn, coastal bermuda grass is often the first name that comes to mind. This specific hybrid variety has been a staple in the southern United States for decades, and for very good reason.
One of the most impressive features of this grass is its incredible drought resistance. Unlike many other turf options, it possesses a deep, aggressive root system that can reach several feet into the soil to find moisture during dry spells.
Because it is a sterile hybrid, it does not produce viable seeds. This means it won’t spread uncontrollably into your neighbor’s flower beds via wind-blown seeds, giving you much more control over your landscape’s boundaries.
Exceptional Forage Quality
For those of you with livestock, this grass is a nutritional powerhouse. It provides high-quality hay and grazing material that is rich in protein when managed correctly with regular fertilization.
It responds incredibly well to nitrogen, meaning the more you care for it, the more it rewards you with rapid growth. This makes it a favorite for hay production and intensive grazing rotations.
Durability and Recovery
Do you have dogs running around or kids playing soccer? This grass variety is famous for its ability to recover from heavy foot traffic and wear.
Its growth habit involves both stolons (above-ground runners) and rhizomes (underground stems). This dual-action spreading mechanism allows it to quickly fill in bare spots and maintain a thick, protective carpet.
Preparing Your Soil for Success
Before you ever put a single sprig in the ground, you need to focus on the foundation. Think of your soil as the “engine room” for your garden; if the engine isn’t tuned, the grass won’t perform.
Start by conducting a comprehensive soil test. Most local university extension offices offer this service, and it is the best ten dollars you will ever spend on your land.
Coastal varieties thrive best in sandy loam soils, but they are remarkably adaptable. However, they are sensitive to pH levels, so you want to aim for a range between 5.5 and 7.0 for optimal nutrient uptake.
Adjusting pH and Nutrients
If your soil test comes back showing high acidity, you will likely need to apply lime. Doing this several months before planting gives the lime time to react with the soil and balance the pH.
Phosphorus and potassium are also vital during the establishment phase. While nitrogen drives top growth, these two elements focus on building that massive root system we talked about earlier.
Eliminating Competition
You want your new grass to have all the resources to itself. This means you must clear the area of existing weeds and “common” bermuda varieties before you begin.
A non-selective herbicide can be used to clear the site. Just be sure to follow the label instructions carefully and allow the appropriate waiting period before you start planting your new sprigs.
The Art of Sprigging and Establishment
Since coastal bermuda grass does not grow from seed, you will need to use a process called sprigging. This involves planting live pieces of the plant, including the roots and stems.
The best time to do this is in the late spring or early summer. You want the soil temperatures to be consistently above 65 degrees Fahrenheit so the plants can “wake up” and start growing immediately.
Timing is everything here. If you plant too early, a late frost could damage the tender sprigs; if you plant too late, the intense July heat might dry them out before they can take root.
Sourcing High-Quality Sprigs
Always buy your sprigs from a reputable grower who can guarantee they are fresh. Fresh sprigs should look green and succulent, not dry, brown, or brittle.
Keep the sprigs moist and shaded until the very moment they go into the ground. If they dry out, the survival rate drops significantly, and you’ll end up with a patchy lawn.
Planting Depth and Spacing
You can broadcast the sprigs over the soil and then use a disc or a specialized sprigging machine to push them into the earth. Aim for a depth of about 2 to 3 inches.
Ensure that a portion of the sprig remains in contact with the moist soil while a small part is near the surface. Firming the soil after planting is crucial to remove air pockets that could dry out the roots.
Nutrient Management: Feeding Your Green Giant
Once your grass is established, it becomes a hungry feeder. To keep it looking like a professional golf course or a high-yield pasture, you need a solid fertilization schedule.
Nitrogen is the primary fuel for coastal bermuda grass. However, applying it all at once is a mistake; the grass can’t use it all, and much of it will simply leach away into the groundwater.
Instead, use split applications. Apply a balanced fertilizer in the spring when the grass starts to turn green, and then follow up with nitrogen-only applications every 4 to 6 weeks during the growing season.
The Importance of Potassium
Many gardeners focus so much on nitrogen that they forget about potassium. This is a huge mistake, especially as you head into the autumn months.
Potassium acts like “antifreeze” for your grass. It strengthens the cell walls and helps the plant store energy, which is vital for surviving winter dormancy and bouncing back quickly in the spring.
Micronutrients and Iron
If your grass looks a bit pale despite plenty of nitrogen, it might be lacking iron or magnesium. A foliar spray of chelated iron can provide a quick “green-up” without forcing excessive growth.
Always water your fertilizer in immediately after application. This prevents “burning” the blades and ensures the nutrients reach the root zone where they are needed most.
Mowing and Maintenance for Peak Performance
Mowing isn’t just about keeping the grass short; it’s a way to stimulate the plant to grow thicker. For a lawn setting, you should aim to keep the height between 1 and 2 inches.
The “one-third rule” is your best friend here. Never remove more than one-third of the leaf blade in a single mowing. If you let it get too long and then scalp it, you stress the plant and invite disease.
For hay production, the strategy changes. You typically want to harvest when the grass is about 12 to 15 inches tall to get the best balance of yield and nutritional value.
Managing Thatch Build-up
Because this grass grows so aggressively, it can develop a layer of “thatch”—a mix of living and dead organic matter between the green blades and the soil surface.
A little thatch is fine, but more than half an inch can block water and nutrients from reaching the roots. Using a vertical mower or power rake in the spring can help keep this under control.
Irrigation Best Practices
While this grass is drought-tolerant, it still needs water to stay green and growing. It is much better to water deeply and infrequently than to give it a light sprinkle every day.
Deep watering encourages the roots to grow further down into the soil. Aim for about one inch of water per week, either from rainfall or irrigation, during the peak of summer.
Managing Pests and Common Challenges
Even the toughest plants have their enemies. Keeping your coastal bermuda grass healthy involves staying vigilant for a few common pests that love this variety as much as we do.
Fall armyworms are perhaps the most notorious threat. These caterpillars can march across a field and strip it bare in just a few days. Check your grass regularly for small, striped larvae, especially in late summer.
If you notice “bird activity” in a specific area of your lawn, it’s often a sign they are feeding on armyworms. Catching them early with a targeted insecticide can save your entire stand of grass.
Dealing with Fungal Issues
During periods of high humidity or excessive rain, you might see signs of leaf spot or rust. These look like small orange or brown freckles on the grass blades.
Usually, these issues resolve themselves when the weather dries out. However, avoiding late-evening watering can help prevent these fungi from taking hold in the first place.
Winter Survival and Greening Up
In colder climates, this grass will go completely dormant and turn a tan color in the winter. Don’t worry—this is perfectly normal and acts as a defense mechanism against the cold.
To ensure a fast “green-up” in the spring, avoid grazing or mowing too low in the late fall. Leaving a little extra height provides insulation for the crown of the plant, where the new growth begins.
Frequently Asked Questions About Coastal Bermuda Grass
Can I plant coastal bermuda grass from seed?
No, you cannot. This variety is a sterile hybrid and does not produce viable seeds. It must be established using sprigs or sod. If you see “Bermuda seed” in a store, it is likely a common variety or a different hybrid blend, but it is not true Coastal.
How much nitrogen does it need per year?
For high-quality hay or a very lush lawn, you may need between 200 and 400 pounds of actual nitrogen per acre, per year, split into several applications. For a standard home lawn, much less is required to maintain a healthy appearance.
Is it safe for horses and cattle?
Absolutely! It is one of the most popular forage grasses for horses and cattle in the South. It provides excellent fiber and, when fertilized properly, has a high protein content that supports healthy weight gain and milk production.
How do I get rid of weeds without killing the grass?
There are many “selective” herbicides designed specifically for use on bermuda grass. These will kill broadleaf weeds like dandelions or clover while leaving your grass unharmed. Always read the label to ensure the product is safe for your specific grass variety.
Conclusion
Growing a beautiful, resilient stand of grass doesn’t have to be a mystery. By focusing on soil health, proper sprigging techniques, and a consistent nutrient schedule, you can create a landscape that is both functional and stunning.
Remember that coastal bermuda grass is a high-performance plant that rewards your efforts. Whether you are raising livestock or just want the best-looking lawn on the block, this grass is a fantastic choice for any sun-drenched property.
