How to Kill Nutsedge in Bermuda Grass
Nutsedge can be a stubborn weed in Bermuda grass lawns. It grows quickly and spreads fast, making it tough to control once it takes hold. Effective removal requires understanding the weed’s behavior and applying targeted methods. This guide will help you learn how to eliminate nutsedge and keep your Bermuda grass healthy and weed-free.
Understanding Nutsedge and Why It Invades Bermuda Grass
Nutsedge, also known as yellow nutsedge or purple nutsedge, is a grass-like weed that looks similar to Bermuda grass. It prefers warm, moist conditions and often invades lawns that have poor drainage or compacted soil. Nutsedge spreads through underground tubers called “nuts,” which can remain dormant for years before sprouting.
Because of its underground tubers, nutsedge can quickly regrow even after surface removal. Knowing this helps you realize that killing nutsedge involves more than just pulling it out—it’s a battle against its underground storage system.
Identifying Nutsedge in Bermuda Grass
Proper identification is essential to control nutsedge effectively. It has a triangular stem shape, unlike Bermuda grass, which has round stems. Nutsedge usually grows taller than Bermuda grass, reaching heights of up to 3 feet.
Look for leaf blades that are V-shaped and pointed, with a rough texture. Additionally, nutsedge produces a seedhead that resembles a cone, which can help confirm its presence.
Early identification helps prevent nutsedge from spreading throughout your lawn and allows for timely weed control measures.
Preventative Measures to Keep Nutsedge Out of Bermuda Grass
Maintain Proper Lawn Care
Good lawn health reduces nutsedge invasion risk. Regular mowing, watering, and fertilization promote dense Bermuda grass that crowds out weeds.
Ensure your Bermuda grass is mowed to the correct height, about 1.5 to 2 inches, to shade out nutsedge and limit its growth.
Improve Drainage and Reduce Soil Moisture
Nutsedge thrives in moist conditions. Aerate your lawn to improve drainage and reduce excess moisture that encourages weed growth.
Address any areas with poor drainage or standing water to prevent nutsedge from establishing itself in your yard.
Avoid Overwatering
Consistent overwatering not only damages Bermuda grass but also creates perfect conditions for nutsedge to flourish.
Water deeply but infrequently, allowing the soil to dry out slightly between watering sessions.
Effective Methods for Killing Nutsedge in Bermuda Grass
Manual Removal Techniques
Removing nutsedge manually involves pulling the weeds and digging out tubers. Use a hand tool or a weeding fork to get under the plant and remove as much of the root system as possible.
Be thorough: leaving behind tubers can lead to rapid regrowth. Regular manual removal is vital in smaller infestations or as a supplementary method.
Using Herbicides Safely and Effectively
Selective herbicides are often necessary for controlling nutsedge without harming Bermuda grass. Look for products containing halosulfuron or sulfentrazone, which target nutsedge specifically.
Always follow label instructions for application rates and timing. Apply herbicides when nutsedge is actively growing for best results.
Apply the herbicide during warmer months, ideally when daytime temperatures are above 70°F, for higher effectiveness.
Timing and Frequency of Herbicide Application
Apply herbicides in early spring or late summer when nutsedge is most active.
Usually, a second application is necessary after 2 to 4 weeks to catch regrowth from tubers that survived the initial treatment.
Do not over-apply, as this can damage Bermuda grass and lead to chemical resistance.
Natural and Organic Controls for Nutsedge
Use of Organic Herbicides
Vinegar-based solutions and other natural herbicides can weaken nutsedge but may not eliminate it entirely. Use them as spot treatments for small patches.
Apply on sunny days to enhance effectiveness and avoid applying before rain, which can wash away the solution.
Mulching and Covering
Applying mulch or a weed barrier fabric can suppress nutsedge growth by blocking sunlight. However, this works best in garden beds rather than lawns.
Regularly replace mulch to prevent nutsedge from pushing through the cover.
Maintenance Tips to Prevent Re-infestation
- Consistent Mowing: Keep Bermuda grass at an optimal height to shade out weeds.
- Proper Fertilizing: Use balanced nutrients to promote dense turf growth.
- Regular Lawn Inspection: Catch nutsedge early before it spreads.
- Drainage Management: Fix areas with poor drainage to reduce moisture levels.
Combining these maintenance strategies with targeted weed control ensures a long-term reduction of nutsedge in your Bermuda grass lawn.
Getting rid of nutsedge in Bermuda grass requires a combination of accurate identification, proper lawn care, and targeted control methods. Regular inspection and maintenance are key to preventing its return. Whether you choose manual removal, herbicides, or organic options, persistence is essential for success. By following these steps, you can restore your lawn to a healthy, weed-free state and enjoy a lush, vibrant Bermuda grass yard.

Frequently Asked Questions
What are effective methods to eliminate nutsedge from Bermuda grass lawns?
To effectively eliminate nutsedge, hand-pull the plants carefully, ensuring you remove the entire tuber system. Applying a targeted herbicide formulated for sedges, such as halosulfuron or sulfosulfuron, provides a chemical solution that can suppress nutsedge growth. Maintaining a healthy Bermuda grass through proper mowing, watering, and fertilization also makes it more resistant to weeds, preventing nutsedge from establishing itself further.
When is the best time to treat nutsedge in Bermuda grass?
The ideal time to treat nutsedge is during its active growing season, typically in late spring and early summer. Applying herbicides when the sedge is actively growing allows the chemicals to be absorbed more effectively. Regular monitoring and early intervention help control the spread before the nutsedge becomes deeply rooted and more difficult to manage.
Can manual removal effectively control nutsedge in Bermuda grass?
Manual removal can help control small patches of nutsedge, but it often isn’t enough for extensive infestations. When pulling nutsedge by hand, ensure you remove the tubers and underground rhizomes completely to prevent regrowth. Combining manual removal with chemical treatments yields better results, especially in heavily infested areas.
Are there any preventative practices to reduce nutsedge recurrence in Bermuda grass?
Yes, preventing nutsedge involves maintaining a dense and healthy Bermuda grass turf through appropriate mowing height, watering practices, and fertilization. Proper drainage reduces standing water, which nutsedge favors. Additionally, avoiding over-application of nitrogen encourages healthy grass growth that can outcompete weeds, reducing the chances of nutsedge establishing in the lawn.
