How to Get Rid of Bermuda Grass in St. Augustine
Understanding Bermuda Grass and Why It Invades St. Augustine Lawns
Bermuda grass is a warm-season grass that spreads quickly through stolons and rhizomes. It is highly resilient and often overtakes St. Augustine lawns, especially in warmer months. Knowing why Bermuda grass invades can help you develop effective removal strategies.
Bermuda thrives in full sunlight and well-drained soil. It’s resistant to drought and foot traffic, making it a tough competitor for your St. Augustine grass. Its rapid growth can quickly create patches that look unsightly and disrupt your lawn’s uniformity.
Identifying Bermuda Grass in Your Lawn
The first step to removing Bermuda grass is to accurately identify it. Bermuda has a fine-textured, dense appearance with dark green color. Its blades are narrow and grow in bunches or mats.
Bermuda spreads by runners that form a thick surface layer. You may notice it creeping over the edges of your St. Augustine grass or forming patches within it. Use a hand lens if needed to examine blades closely.
Why Is It Difficult to Remove Bermuda Grass?
Bermuda grass is difficult to eradicate because of its extensive root system and vigorous growth habits. Its rhizomes and stolons can survive underground and re-sprout even after mowing or surface removal.
Regular lawn maintenance often encourages Bermuda’s spread, making it persistent. Complete removal requires consistent effort and multiple techniques for best results.
Methods for Removing Bermuda Grass
Manual Removal: The First Step
Manual removal is best suited for small patches or as an initial step. Use a garden spade or sod cutter to carefully dig out Bermuda grass. Make sure to remove as much of the root system as possible to prevent regrowth.
After digging, collect all the cuttings and dispose of them properly. Leaving fragments behind can lead to new Bermuda patches. Be vigilant about inspecting your lawn regularly for emerging Bermuda shoots.
Chemical Control: Herbicides and Their Use
Applying selective herbicides is an effective way to target Bermuda grass without harming St. Augustine. Look for products containing glyphosate or sethoxydim.
Follow the instructions precisely, applying during warmer months when Bermuda is actively growing. Multiple applications may be necessary for complete eradication. Be cautious to avoid overspraying onto your St. Augustine grass.
Using Non-Selective Herbicides
In cases of severe Bermuda infestation, non-selective herbicides like glyphosate can be used to eliminate all grass. This method requires caution as it kills all plants it contacts.
After application, wait for the Bermuda grass to die off completely before reseeding or laying new sod. Always wear protective gear and follow safety guidelines when handling chemicals.
Preventing Bermuda Grass Returns
Prevention is key after successful removal. Maintain a healthy, dense St. Augustine lawn by proper watering and fertilization. A thick turf leaves less room for Bermuda to establish itself.
Regular mowing at the correct height (around 3 inches for St. Augustine) discourages Bermuda’s growth. Use lawn aeration and overseeding to keep your grass resilient against invaders.
Preventive Landscaping Tips
To reduce Bermuda’s chances of re-invasion, consider the following tips:
- Maintain proper lawn drainage to avoid waterlogging which Bermuda prefers.
- Limit foot traffic on the lawn to prevent spreading rhizomes and stolons.
- Use mulch or landscape fabric in problem areas to suppress Bermuda growth.
- Install physical barriers like edging to prevent Bermuda from creeping into your lawn.
Effective Lawn Care Practices to Combat Bermuda
Consistent lawn care helps keep Bermuda at bay. Regularly water your St. Augustine deep and infrequently to promote deep root growth.
Fertilize appropriately using nitrogen-rich formulas to improve turf density. Proper mowing height prevents Bermuda from gaining an advantage over your grass.
Alternative Methods to Control Bermuda Grass
Some homeowners opt for organic or natural remedies, though they might be less immediate. Applying vinegar solutions or boiling water can weaken Bermuda patches, but may also harm surrounding grass.
Using smothering techniques like plastic sheeting or black tarp over Bermuda patches for several weeks can starve the rhizomes of light and energy. These methods require patience but can be effective over time.
Professional Lawn Services
If Bermuda grass persists despite your efforts, professional lawn care services can provide specialized treatments. They can perform targeted herbicide applications and advise on best practices for your particular lawn situation.
Consulting with turf specialists ensures an integrated plan combining removal, prevention, and ongoing maintenance.

Frequently Asked Questions
What are effective methods to prevent Bermuda grass from invading St. Augustine lawns?
To prevent Bermuda grass from spreading into your St. Augustine lawn, maintain healthy turf through proper fertilization, watering, and mowing practices. Regular overseeding of dense, healthy St. Augustine grass creates a thick canopy that makes it difficult for Bermuda grass to establish. Additionally, avoid overwatering, which encourages Bermuda growth, and use sod or seed that are resistant to Bermuda grass intrusion. Installing physical barriers like edging can also hinder Bermuda grass from creeping into your lawn areas.
How can herbicides be used safely to eliminate Bermuda grass in St. Augustine lawns?
Select a selective herbicide formulated specifically for Bermuda grass control, ensuring it targets Bermuda while sparing your St. Augustine grass. Apply the herbicide during active Bermuda growth periods, typically in late spring or early summer, following the manufacturer’s instructions carefully. Avoid overlapping applications to prevent damage to your St. Augustine turf. Always water the lawn after application to help the herbicide penetrate Bermuda grass tissues, and monitor the site regularly for regrowth, reapplying as needed.
What are natural approaches to eradicate Bermuda grass from a St. Augustine yard?
Natural methods include manual removal of Bermuda grass by carefully digging out the roots and rhizomes, ensuring you remove all underground fragments to prevent regrowth. Apply thick layers of mulch or overseed with dense St. Augustine grass to shade out Bermuda patches, limiting sunlight exposure. Consistent mowing at the recommended height for St. Augustine helps weaken Bermuda grass over time. These approaches require patience but can effectively reduce Bermuda grass presence without chemical use.
How often should I monitor my lawn to control Bermuda grass reinfestation?
Regularly inspect your lawn every two to three weeks during the growing season to identify early signs of Bermuda grass spreading. Early detection allows you to take prompt action, whether through manual removal or targeted herbicide application. Consistent monitoring helps prevent Bermuda grass from establishing a strong foothold, maintaining the health and appearance of your St. Augustine lawn over time.
Can adjusting lawn care practices help suppress Bermuda grass growth?
Yes, adjusting your lawn care practices can effectively suppress Bermuda grass. Mow your lawn at the proper height for St. Augustine, typically around 3 inches, to promote dense growth that crowds out Bermuda. Water deeply but infrequently to encourage strong root development, and fertilize appropriately to maintain vigorous turf.
