common weeds in bermuda grass
Bermuda grass is a tough, sun-loving warm-season turf, but it isn’t invincible. Because it grows aggressively via stolons and rhizomes, it usually does a great job of crowding out competition. However, certain common weeds in bermuda grass are specifically adapted to thrive in the same conditions your lawn loves.
When you spot a weed, don’t panic! Most of these invaders fall into two main categories: grassy weeds and broadleaf weeds. Grassy weeds look like your lawn but have different growth habits, while broadleaf weeds are easy to spot with their wide leaves and occasional flowers.
Understanding which one you are dealing with is vital because the treatment for a dandelion will not work on crabgrass. Let’s take a closer look at the most frequent visitors you’ll likely encounter in your backyard sanctuary.
Crabgrass: The Summer Nightmare
If there is one weed that strikes fear into the heart of a gardener, it is crabgrass. This annual grassy weed thrives in the heat of summer, exactly when your Bermuda grass is at its peak. It spreads by seeds and can produce thousands of them in a single season.
You can identify it by its prostrate growth habit, meaning it grows low to the ground and spreads outward like the legs of a crab. It often has a slightly lighter green or yellowish tint compared to your dark green Bermuda blades.
Dandelions: The Persistent Perennials
Dandelions are perhaps the most recognizable broadleaf weeds. While kids love their yellow flowers and fluffy seed heads, gardeners know they possess a deep taproot that makes them incredibly difficult to pull manually.
If you leave even a small piece of that root in the ground, the plant will likely grow back. These are perennials, meaning they will return year after year unless you address the root system directly.
Nutsedge: The Sedge That Isn’t a Grass
Nutsedge, often called “nutgrass,” is a tricky one. It looks like grass, but it is actually a sedge. You can tell the difference by feeling the stem; sedges have triangular stems, which you can feel by rolling them between your fingers.
It grows much faster than Bermuda grass, often sticking up several inches above the lawn just a day or two after you mow. It loves wet, poorly drained soil, so its presence might be a sign you are overwatering.
Identifying Grassy Weeds vs. Broadleaf Weeds
To effectively manage common weeds in bermuda grass, you must be able to tell your “foes” apart. This distinction dictates which herbicides you buy and when you apply them. Using the wrong product can result in wasted money or, worse, a damaged lawn.
Grassy weeds are monocots, just like your turf. This makes them particularly difficult to kill because many chemicals that target them will also harm your Bermuda grass. Broadleaf weeds are dicots, which generally makes them easier to target with selective herbicides.
Common Grassy Weeds
- Goosegrass: Often found in compacted soil, this weed has a silver-white center and grows in a flattened rosette.
- Dallisgrass: A perennial that grows in thick clumps. It has tall seed stalks with black spots that are very distinct.
- Annual Bluegrass (Poa Annua): This winter weed pops up when your Bermuda is dormant, creating bright green patches in a brown lawn.
Common Broadleaf Weeds
- White Clover: Recognized by its three-lobed leaves and white ball-shaped flowers. It often indicates low nitrogen levels in your soil.
- Henbit: A winter annual with square stems and small purple flowers. It thrives in the early spring before the grass wakes up.
- Chickweed: This weed forms dense, fleshy mats and has small white star-shaped flowers. It loves cool, moist, and shady areas.
The Best Defense: Pre-Emergent Timing
The secret to a low-maintenance lawn isn’t killing weeds—it’s preventing them from ever showing up. This is where pre-emergent herbicides come into play. These products create a chemical barrier in the top layer of soil that stops weed seeds from successfully sprouting.
Timing is everything here. If you apply it too late, the seeds have already germinated, and the product will be useless. If you apply it too early, the barrier may break down before the seeds are ready to pop.
For summer weeds like crabgrass, you should apply your pre-emergent when soil temperatures reach about 55 degrees Fahrenheit for three consecutive days. For winter invaders, aim for the fall when soil temperatures drop below 70 degrees.
Pro Tip: Use a simple soil thermometer or check local agricultural extensions online to get the exact timing for your specific zip code. It makes a world of difference!
Post-Emergent Solutions for Stubborn Invaders
Even with the best prevention, a few common weeds in bermuda grass will likely sneak through. When they do, you need a post-emergent herbicide. These are designed to kill weeds that are already visible and growing.
When choosing a product, look for “selective” herbicides. These are formulated to kill the weed while leaving your Bermuda grass unharmed. Always read the label carefully; some products are safe for Fescue or St. Augustine but will turn Bermuda grass brown.
Spot-treating is usually better than “blanket” spraying your entire yard. It uses less chemical and reduces the stress on your turf. Use a small hand sprayer and target only the weeds you see.
Safety Warning: Never spray herbicides on a windy day. The “drift” can carry the chemicals onto your prized rose bushes or vegetable garden, causing accidental damage.
Cultural Control: How to Outsmart Weeds Naturally
The best weed killer is a thick, healthy lawn. When your Bermuda grass is dense and lush, there is simply no room for weed seeds to reach the soil and find sunlight. This is known as “cultural control.”
Think of your lawn as a competitive athlete. If you give it the right food, water, and “training,” it will outperform the competition every time. Here is how you can help your grass win the battle against common weeds in bermuda grass.
Mow High and Often
While Bermuda can be kept quite short, letting it grow to the higher end of its recommended height (around 1.5 to 2 inches) can help shade the soil. This shade prevents weed seeds from getting the light they need to germinate.
Always follow the one-third rule: never remove more than one-third of the grass blade in a single mowing. Scalping the lawn stresses the grass and opens up “bald spots” where weeds love to move in.
Water Deeply but Infrequently
Frequent, shallow watering encourages shallow roots. This is exactly what weeds like crabgrass love. Instead, water your lawn deeply—about one inch per week—in a single session or two.
This forces the Bermuda roots to grow deep into the soil to find moisture. Deep roots make your lawn more drought-tolerant and much more resilient against weed invasions.
Aeration and Thatch Management
Bermuda grass is prone to thatch buildup—a layer of dead organic matter between the grass and the soil. Too much thatch prevents water and nutrients from reaching the roots. Core aeration every year or two helps break up this layer and reduces soil compaction.
Weeds like goosegrass thrive in compacted soil where grass struggles. By keeping your soil “breathable,” you give your turf the advantage it needs to stay dominant.
Organic Weed Management for Eco-Friendly Gardeners
If you prefer to keep chemicals out of your backyard, you can still manage common weeds in bermuda grass effectively. It requires a bit more elbow grease, but the results are worth it for the environment and your pets.
Manual pulling is the most direct organic method. For weeds with taproots like dandelions, use a “weeding tool” or a long screwdriver to ensure you get the entire root. Doing this after a rain when the soil is soft makes the job much easier.
Corn gluten meal is a popular organic pre-emergent. It doesn’t work quite as effectively as synthetic versions, but it adds nitrogen to the soil while inhibiting seed germination. Just be sure to apply it at the correct time in early spring.
You can also use horticultural vinegar (20% acetic acid) for spot treatments on sidewalks or driveways. Be very careful, though—vinegar is non-selective and will kill your Bermuda grass just as quickly as the weeds!
Frequently Asked Questions About common weeds in bermuda grass
Does Bermuda grass choke out weeds?
Yes, a healthy and well-maintained Bermuda lawn is very effective at choking out weeds. Its aggressive growth habit allows it to fill in bare spots quickly. However, if the lawn is thin due to shade, poor nutrition, or improper mowing, weeds will take advantage of the weakness.
Will vinegar kill weeds without hurting my Bermuda grass?
No. Vinegar is a non-selective herbicide, meaning it will kill almost any green plant it touches. If you spray vinegar on a weed in the middle of your lawn, you will likely end up with a dead brown circle of grass surrounding the weed. Use vinegar only for cracks in pavement or areas where no grass is present.
When should I apply weed killer to my Bermuda lawn?
For pre-emergents, apply in early spring (February/March) and again in fall (September/October). For post-emergents, you can apply them whenever you see active weed growth, provided the temperature is not too high. Most herbicides should not be used when temperatures exceed 85-90 degrees Fahrenheit, as this can burn the grass.
Why do I have so much clover in my grass?
Clover is a “nitrogen fixer,” which means it can pull nitrogen from the air. It often appears in lawns that are nitrogen-deficient. If you see a lot of clover, it might be a sign that your Bermuda grass needs a high-nitrogen fertilizer to help it regain its strength and crowd out the clover.
Conclusion
Dealing with common weeds in bermuda grass doesn’t have to be a losing battle. By understanding the lifecycle of these plants and using a combination of prevention, proper maintenance, and targeted treatments, you can achieve that picture-perfect lawn you’ve always wanted.
Remember, the goal isn’t just to kill the weeds, but to create an environment where your grass is so healthy that weeds don’t stand a chance. Focus on deep watering, regular mowing, and timely fertilization.
Don’t get discouraged by a few yellow flowers or strange blades of grass. Gardening is a journey, and every weed is just a little reminder to give your lawn a bit more love. Go forth and grow—your emerald carpet is waiting!
