Bermuda grass creeping into your lawn or garden can feel like an endless battle. As a lawn specialist, I’ve seen how invasive Bermuda grass (sometimes dubbed devil’s grass) takes over flower beds and cool-season lawns, often frustrating gardeners. The good news is that with patience and the right approach, you can get rid of Bermuda grass or at least control it.

In this comprehensive guide, we’ll walk through all possible methods: from old-fashioned digging and smothering to selective herbicides, to help you regain control of your landscape. My goal is to share a cultural and tractable plan that covers how to remove, kill, or suppress Bermuda grass, whether you prefer natural methods or targeted chemical solutions. Let’s tackle this pesky grass together so you can restore a healthy, beautiful yard.

Understanding Bermuda Grass and Why It’s a Problem

Before we get into the “how,” it’s worth pausing to understand why Bermuda grass is so tough and tenacious.

Bermuda Grass Characteristics

Bermuda grass (Cynodon dactylon) is a warm-season perennial grass known for its aggressive growth. It thrives in full sun and high temperatures, which is why it’s a popular turf grass in the southern United States. It has a coarse texture and can form a dense mat of lawn when wanted, but when it invades areas it doesn’t belong, it behaves like a weed.

Bermuda grass spreads through multiple means: seeds, above-ground runners (stolons), and underground stems (rhizomes). This triple threat of reproduction makes it extremely persistent. In fact, the grass was once valued as a hardy pasture and turf species, but gardeners now know it as a “nightmare” because of how easily it invades and outcompetes other plants. It’s not picky about soil and can tolerate drought and foot traffic. About the only thing Bermuda grass doesn’t tolerate well is shade; it loves sunlight and open space to run.

Why Is Bermuda Grass So Hard to Kill?

Bermuda grass is hard to kill because it has multiple survival strategies:

• Spreading Stolons and Rhizomes: Parts of the adaptations of Bermuda grass are the spreading stolons (above the ground) and rhizomes (below the ground); these parts can develop roots at the nodes and create new plants. These runners can snake under fences, through flower beds, even over sidewalks; one gardener found stolons 3 feet long crawling across a driveway!. If any segment of stolon or rhizome is left in the soil, it can sprout a new plant.
• Deep Energy Reserves: Bermuda grass is known for storing lots of energy in its roots and rhizomes. Even if you kill the top growth, the deep roots use the stored energy to activate new growth and regrow new shoots. It can take a long, sustained effort to deplete these reserves so the plant finally dies.
• Fast Growth and Tough Foliage: In warm weather, Bermuda grass grows rapidly, which means it quickly rebounds after cutting or partial removal. It also can go dormant (turn brown) in cool weather or drought, then green up again when conditions improve. This survival tactic makes it “almost impossible to kill” outright in a single attempt.
• Viable Seed Bank: Besides its vines, Bermuda also spreads by seed. Seeds can remain viable in soil for years, waiting to germinate. This means even after you eliminate established grass, new seedlings can pop up later from the seed bank.
• Drought and Damage Tolerance: Bermuda grass can go dormant (turn brown) when conditions are bad, like in cold or drought, and then rebound from its roots when things improve. It’s not easily discouraged by lawn treatments that might kill other weeds.

There is no single “magic bullet” for eradicating Bermuda grass. Trust me, I wish there were! Instead, you’ll likely need to use a combination of approaches. The best method for you depends on your situation: how large the infested area is, whether it’s mixed into a lawn or among cherished plants, and your tolerance for using herbicides.

Below, I’ve outlined all the possible methods to get rid of Bermuda grass, including manual removal, smothering techniques, lawn care practices, and chemical options. You can choose one or use several together for a more effective strategy. Let’s explore each in detail.

Method 1: Manual Removal Strategies

When dealing with Bermuda grass, manual removal (physically digging or pulling it out) is the most straightforward approach. It’s labor-intensive, but it’s chemical-free and can be quite effective for smaller areas or initial cleanup. The key is to be thorough; you need to remove not just the green blades but also the stolons and as much of the root/rhizome as possible. Here are some manual methods and tips:

Hand-Pulling and Digging

For isolated patches or small garden beds, hand-pulling can work if you’re diligent. The soil should be moist (it makes it easier to pull roots). Use a weeding tool or garden fork to loosen the soil around the Bermuda grass clump, then pull slowly to extract the entire root system if possible. Don’t just rip the tops off! You want to get the wiry, spaghetti-like rhizomes out from underground. According to experts, even a tiny piece of Bermuda rhizome left behind can regenerate a new plant, so try to remove every bit you see.

After pulling Bermuda grass, do not toss it onto your compost pile or leave it lying around. This weed doesn’t need encouragement – even a discarded stolon on moist soil can take root again. Bag it up and dispose of it, or let it dry out completely on a hard surface (like baking in the sun on a driveway) before discarding. I’ve learned this the hard way by seeing “dead” runners spring back to life when left on the ground!

Hand-pulling Bermuda is not a one-and-done chore. Check back every week or two and yank out any new sprouts emerging from leftover roots. Persistence will gradually deplete the grass’s energy reserves.

Tip: Dig Deep: When hand-digging, get at least 6 inches (15 cm) deep if you can. Bermuda’s roots can dive that far or more. I often use a spade or fork to loosen a wide circle around the infestation, then sift through the soil for any white or light-brown rhizome pieces. Some determined gardeners even sift soil through a screen to catch small rhizome fragments. It’s tedious, but it shows how thorough you sometimes need to be.

Using a Sod Cutter for Large Areas

If a large section of lawn (or a whole garden plot) is overrun with Bermuda grass, manually digging each rhizome might be impractical. In such cases, a sod cutter can be a lifesaver. A sod cutter is a machine (available at many equipment rental shops) that slices under the grass and rolls it up like a carpet. Using it, you can remove the top 1–2 inches of turf and soil in strips. This will take the majority of Bermuda’s stolons and some shallow rhizomes with it. It’s a fast way to clear an area down to mostly bare soil.

However, note that Bermuda’s deeper rhizomes might still remain in the ground after using a sod cutter. Once you’ve peeled up the sod, it’s a good idea to go back over the area and dig up any remaining thick white roots you see. Also, dispose of the removed sod carefully (don’t reuse it elsewhere unless you want Bermuda there). This method basically gives you a clean slate to either re-sod or reseed with a desirable grass or to establish a garden bed.

• Pros: Sod cutters cover large areas quickly and can physically remove the bulk of the Bermuda grass in one go. Great for lawn conversion projects.
• Cons: They’re heavy machines and require some muscle to operate. You’ll lose whatever topsoil and other plants are in those strips. And if any rhizomes are deeper than the cut, they could regrow.

The Pitfalls of Tilling (and When to Use It)

It might be tempting to rototill an area full of Bermuda grass to “chew it up.” Be cautious with tilling! In many cases, tilling makes a Bermuda problem worse. Here’s why: the tiller blades chop the rhizomes and stolons into many small pieces and distribute them through the soil, and each little piece can potentially start a new plant. You could end up turning one Bermuda patch into dozens. Unless you plan to follow up with careful removal or herbicide, rototilling is usually not recommended as a first step for Bermuda removal.

That said, there are a couple of scenarios where tilling can help in the overall strategy (usually in combination with other methods):

• Expose Rhizomes to Elements: In cold climates, some folks till late in the season to bring rhizomes to the surface before winter, hoping the freeze will kill them. This might marginally weaken the grass, but don’t expect total eradication just from one freeze.
• Before Smothering: You might lightly till to break up the soil and existing turf if you plan to immediately do a smothering method (like sheet mulching, which we’ll cover next). This can make it easier to lay materials and might expose rhizomes to drying out. But again, you must then smother or remove all those bits you just churned up.
• In Combination with Herbicide: Occasionally, tilling after an herbicide treatment (once the grass is mostly dead) can help mix organic matter and speed up decomposition of the dead roots. But don’t till live Bermuda without a plan to deal with the consequences.

Bottom line: Avoid rototilling live Bermuda grass if you can. If you do till, be prepared to follow up by hand-picking rhizomes or immediately smothering the area to prevent re-sprouting.

Method 2: Smothering and Solarization Techniques

Since Bermuda grass needs sunlight to thrive, an effective non-chemical approach is to smother it or “cook” it by solarization. These methods aim to deprive the grass of light (and sometimes generate heat) until it dies out. Smothering is a go-to solution for organic gardeners and those converting a lawn to garden beds. Let’s go through the main techniques:

Cardboard, Newspaper, and Mulch Layering (Sheet Mulching)

Another effective smothering strategy is sheet mulching, sometimes called lasagna gardening. This involves layering cardboard or newspaper over the Bermuda grass and covering it with mulch or soil, creating a barrier that blocks light and physically hinders the grass. Unlike clear plastic solarization, this method doesn’t rely on heat as much as sheer light deprivation (occultation) and gradual decomposition to kill the grass.

Sheet mulching essentially suffocates the Bermuda grass. Without light for months, the grass uses up its root reserves and dies. I’ve had good success with this method for converting sections of Bermuda lawn into garden beds. It’s labor up front to gather cardboard and mulch, but then nature takes over. By the time you remove the covering (or it decomposes in place), you should have weed-free soil ready to plant. In one Organic Growers School case, the gardener reported this was effective with a long-term plan to do the whole yard over time.

Here’s how to do it:

Sheet Mulching Steps:

1. Scalp and Clean Up: Mow or weed-whack the Bermuda as low to the ground as possible, ideally scalping it. Remove any loose grass clippings or stolon pieces (you don’t want them lifting your cardboard).
2. (Optional) Compost Layer: Some gardeners add a thin layer of compost or manure on the ground before the cardboard. This isn’t to feed the Bermuda but to encourage soil microbes that will help break down the grass and cardboard over time. It’s optional but can enrich the soil during the process.
3. Lay Cardboard/Newspaper: Flatten large cardboard boxes (remove any plastic tape) and lay them two layers thick over the entire area to cover. Overlap the edges of cardboard generously (6 inches or more) so no gaps show. Alternatively, use 8-10 layers of newspaper. The goal is a continuous light-blocking sheet.
4. Wet It Down: Soak the cardboard/newspaper thoroughly with water. Wet cardboard molds to the ground better and helps start the decomposition.
5. Secure the Edges: Use garden staples, sod staples, or rocks to pin down the cardboard, especially at overlaps. This prevents Bermuda from sneaking under or wind from blowing material away.
6. Mulch Deeply: Cover the cardboard with a thick layer of mulch, about 3–6 inches of wood chips, straw, pine bark, or similar. A thick mulch layer further blocks light and also weighs down the cardboard. Plus, it makes the area look tidier (important if this is a front yard!). Plain mulch alone usually isn’t enough for Bermuda, but mulch on top of cardboard creates a formidable barrier.
7. Wait and Monitor: Leave the sheet mulch in place for several months. The recommendation is at least 4–6 months of coverage. During that time, periodically check for any Bermuda trying to creep in from the sides or popping up in weak spots. Do not dig through or plant into the cardboard during this period, you’d give Bermuda an opening. If you see any grass blades poking through, snip or pull them off immediately so they don’t get sunlight.

A few cautions: Make sure the coverage is complete; any gap or tear is an entry point for Bermuda to re-emerge. Also, Bermuda at the edges of your sheet mulch will try to creep on top if it can, so watch the borders (you might need to do extra trenching or edging there). And remember, this is a long game; patience is required, but it’s very environmentally friendly and improves your soil as a bonus (the cardboard and mulch break down into organic matter).

Solarization with Plastic Sheets

Solarization involves covering the infested area with plastic to trap heat from the sun, essentially baking the weeds underneath. Typically, clear plastic is used to let sunlight through and create a greenhouse effect, heating the soil to lethal temperatures for plants. For Bermuda grass, solarization can indeed kill a lot of the top growth and even some shallow roots by overheating them. It usually takes 4–6 weeks of summer sun for solarization to have a strong effect.

However, be aware: solarization alone may not completely eradicate Bermuda grass. Extension experts note that while it will suppress Bermuda (and can kill the leaves and some roots), the deeper rhizomes often survive, especially if the plastic isn’t left long enough. In one Q&A, an expert said clear plastic will kill the tops but “the underground stems (rhizomes) and roots will most likely survive and when you remove the plastic the grass will return”. So think of solarization as a way to greatly weaken Bermuda grass and make it easier to control afterward, rather than a guaranteed one-step cure.

How to solarize:

1. Mow and Moisten: First, mow or cut the Bermuda grass as low as possible and remove the clippings. Water the area well; moist soil conducts heat better.
2. Cover Tightly: Use a large sheet of clear plastic (2–6 mil painter’s plastic works). Spread it over the area and bury or weigh down the edges with soil, rocks, or boards. It’s crucial to seal the edges so heat can’t escape. You want essentially an oven under there.
3. Bake in the Sun: Leave the plastic in place for at least 4 weeks, preferably 6–8 weeks during the hottest part of summer. The sun will raise soil temps under the plastic significantly (often 140°F+/60°C in the top inches).
4. Monitor and Repeat if Needed: Peek under the plastic after a month; you should see browned, dead vegetation. If some hardy green patches remain, you might shuffle the plastic or re-cover for a few more weeks. In very bad infestations, you could solarize again the next summer.

One tip: you can enhance solarization by first tilling or disturbing the area, then immediately covering. Tilling exposes more rhizomes to heat and drying. One extension expert suggested tilling halfway through the solarization period (lift the plastic, till up any surviving roots, then cover again) to expose buried rhizomes to the high temps.

Solarization in action: a sheet of clear plastic covers a Bermuda grass area, with edges weighted down (in this case by tubs and bricks). The intense summer sun heats and steams the grass underneath, turning it brown within days.

Solarization has the bonus of killing other weeds and many soil pests too. According to the University of California IPM program, clear plastic solarization in summer can eradicate Bermuda grass plants and seeds in the soil under the right conditions. It’s one of the few methods that deal with the seed bank. Just remember that it’s weather-dependent; you need strong sun and warm temperatures for it to work effectively.

If done properly, solarization can significantly knock back the Bermuda grass. However, like other methods, you should stay vigilant for any new growth. Occasionally, a few survivors at the edges or stray seeds might return, so be prepared to do a follow-up treatment or hand-pull any stragglers.

Method 3: Lawn Care and Cultural Controls

When Bermuda grass invades a lawn of another grass type (like a fescue or bluegrass lawn), you have an extra challenge: you want to get rid of the Bermuda without destroying your desirable turf. This is tricky, because most methods that kill Bermuda (like non-selective herbicides or solarization) will also harm the lawn you want to keep. However, there are some cultural practices that can tilt the playing field against Bermuda grass and in favor of your lawn grass. Even in garden beds, certain cultural approaches can make the environment less friendly to Bermuda. Let’s discuss these:

Mowing High to Shade Out Bermuda

One of the simplest (and surprisingly effective) methods to combat Bermuda in a cool-season lawn is to raise your mowing height. Bermuda grass cannot tolerate shade or tall competition very well. Cool-season grasses like tall fescue, on the other hand, can grow taller and thicker. By mowing your fescue or bluegrass lawn at the upper end of its recommended height range, you create a canopy that shades the soil. This puts the sun-loving Bermuda at a disadvantage beneath the taller turf.

In fact, research has shown that mowing tall fescue at about 4 inches can completely kill Bermuda grass over time, even without herbicides. At that height, the fescue is so tall and dense that the Bermuda grass underneath essentially starves from lack of sunlight. As a lawn pro, I often advise clients with Bermuda encroachment to “embrace the shaggy”; let that lawn grow out a bit! It might not look like a golf course, but a slightly taller lawn is healthier and can naturally crowd out weeds like Bermuda.

How to do it: Adjust your mower to ~4 inches (or the highest setting if it doesn’t have measurements). Ensure the blades are sharp (tall grass cuts better with sharp blades). You may need to mow a bit more frequently since the grass can flop over if it gets too tall between mowings. But the goal is a consistently higher cut. Over a season or two, you may notice the Bermuda patches thinning or disappearing as the fescue thrives above it.

Bonus Benefits: Higher mowing heights not only shade out Bermuda, but also improve your lawn’s drought resistance and disease resistance. It’s a win-win for your desirable grass. Just remember, if you ever scalp the lawn or drop mowing height, the Bermuda could resurge; so keep it tall consistently if Bermuda is a known problem.

Encouraging Dense Turf or Cover Crops

Another cultural strategy is to make sure Bermuda grass has competition. In lawns, this means keeping your desired turfgrass thick and healthy. In gardens, it could mean using cover crops or dense plantings to occupy space. The idea is that bare soil or thin spots are an open invitation for Bermuda to invade (or re-invade). By minimizing bare patches, you reduce the foothold Bermuda can get.

For lawns:

Fertilize and Overseed: Maintain a proper fertilization schedule for your lawn grass and overseed any thin areas each year (for example, overseeding fescue in fall). A lush lawn will leave little room for Bermuda runners to take hold. Also, water and care for the lawn appropriately; stress to the lawn (like drought or disease) can weaken it and give Bermuda an opening. The Virginia Cooperative Extension emphasizes that a strong cool-season turf, managed well, is crucial if you want to beat Bermuda. Cultural control isn’t just an “extra”; it’s a necessary part of the program.

Shade and Landscape Design: If you have areas where Bermuda is persistent, consider if you can add a shade tree, shrub, or taller plants. Increasing shade is a long-term approach, but since Bermuda hates shade, a shift in the environment can naturally suppress it. I’ve seen clients effectively push Bermuda back by planting groundcovers or shrubs in former Bermuda-invaded open areas. Obviously, this depends on your landscape goals, but it’s a thought.

For gardens or bare soil:

Plant Cover Crops: If you have a vegetable garden or a patch of soil you’re resting, planting a cover crop can help compete with Bermuda. Certain cover crops (like sorghum-sudangrass) grow tall and thick, shading the soil heavily. They also use up water and nutrients that Bermuda would need. One study noted sorghum-sudangrass cover crop “exhausts bermudagrass from its desired full sun requirements by blocking sunlight”. After the season, you can till in the cover crop (being mindful of Bermuda pieces as discussed). While cover cropping won’t eliminate Bermuda alone, it’s an organic tool to suppress it and improve soil in the meantime.

Dense Plantings & Mulch: In landscape beds, aim for dense plant spacings so that Bermuda has fewer gaps to exploit. Use thick mulch layers (3–4 inches of wood chips or bark) between plants to block light to the soil. Be aware, however, that mulch by itself can sometimes act as a nice loose surface for Bermuda runners to creep through unless it’s very thick. As one study cautioned, four inches of mulch alone wasn’t enough; Bermuda grass happily crawled through it unless combined with other measures.

Method 4: Chemical Control Options

When natural or manual methods aren’t enough (or are too laborious), herbicides can be effective tools for getting rid of Bermuda grass. As a professional, I always recommend using chemicals carefully and according to label directions, but I also know that for tough weeds like Bermuda, the right herbicide can save a lot of time and frustration. Here we’ll discuss both non-selective and selective herbicide options, as well as some “natural” or organic herbicide ideas and their limitations.

Non-Selective Herbicides (Glyphosate & Others)

“Non-selective” herbicides are those that kill any vegetation they contact. The most common example is glyphosate, widely sold under brand names like Roundup®. Glyphosate is a systemic herbicide, meaning it’s absorbed by the leaves and travels throughout the plant to the roots. This makes it particularly effective on Bermuda grass because it can reach those deep rhizomes and stolons.

According to an Oklahoma State University study, glyphosate was one of the very few treatments that provided significant long-term suppression of Bermuda grass. It essentially kills the whole plant, not just the foliage, which is what you need for a pernicious weed like this.

Using glyphosate for Bermuda grass:

When to apply: It’s best to apply when Bermuda grass is actively growing and green. Many experts suggest treating in late summer (August/early September) when the plant is storing energy in its roots for winter; that way, it will draw the herbicide down into the roots more effectively. Warm, sunny weather (but not drought-stressed conditions) is ideal. Avoid spraying if rain is expected within 24–48 hours (check the label; many glyphosate products need rain-free period to fully absorb).

How to apply: For spot-treating small patches, use a handheld spray or a wicking applicator (some gardeners use a sponge or foam brush to “wipe” glyphosate onto Bermuda runners in a flower bed, for precision). For larger areas or a whole lawn renovation, you might use a pump sprayer or even a hose-end sprayer. Ensure good coverage on the Bermuda leaves, it needs to hit the green parts. But be very careful to avoid drift onto plants or lawn you want to keep; remember, non-selective means it can kill your roses or tomato plants or fescue just as easily as the Bermuda! I often do a calm-wind morning or evening to spray, to minimize drift.

Multiple applications: One glyphosate treatment usually won’t completely kill established Bermuda. You’ll likely see it yellow and brown out in a couple weeks, then some survivors will green up again. Plan on at least 2–3 rounds of spraying, spaced a few weeks apart. A common lawn renovation approach is: spray in midsummer, water and let regrowth happen, spray again late summer, then a third time if needed. Only then replant your new grass in early fall. This ensures you really knocked it down. (In a Virginia Tech guide, they specifically advise glyphosate in late June/July, repeat in 3-4 weeks, then re-seed in early September.)

Other non-selective herbicides are glufosinate or diquat (which often is combined with glyphosate in products). Those can scorch Bermuda quickly but may not translocate to roots as effectively as glyphosate. In the OSU study, a glyphosate + diquat mix showed good short-term burn and some control – diquat gives the “quick visual kill” while glyphosate does the deep work. There are also organic non-selectives like strong acids or oils (e.g. pelargonic acid, clove oil mixtures). These burn down the foliage but, as the study noted, they didn’t really touch the rhizomes.

Always read the label for any herbicide. Wear protective clothing and apply as directed. Glyphosate has specific instructions like not mowing a few days before/after application, etc.

Selective Grass-Specific Herbicides

Selective herbicides are those that target certain types of plants while sparing others. When dealing with Bermuda grass in, say, a fescue lawn or in flower beds, a selective herbicide can be a game-changer because it can knock back the Bermuda without killing everything else in the vicinity.

For Bermuda grass, the selective options usually fall into grass killer herbicides (also known as graminicides). These are formulated to kill grassy weeds in broadleaf settings or sometimes to selectively kill one grass in the presence of another. A few examples and scenarios:

• Fusilade II (fluazifop-P-butyl): This is a grass killer that is often mentioned as effective on Bermuda. It’s labeled to selectively remove Bermuda grass from certain settings. For example, Fusilade can be used to kill Bermuda out of zoysia grass lawns, fescue lawns, and even out of groundcover beds.
• Fenoxaprop (Acclaim Extra): Fenoxaprop is another post-emergent grass herbicide that can suppress Bermuda in cool-season lawns. It’s primarily for annual grasses, but at high rates it can damage Bermuda. It tends to be more effective in late season and often is tank-mixed with other products like triclopyr (Turflon) for synergy.
• Triclopyr (Turflon Ester): Triclopyr is actually a broadleaf herbicide, but interestingly, when combined with some grass killers, it boosts the effect on Bermuda. Some selective Bermuda control programs use Turflon + Fenoxaprop, or Turflon + fluazifop, or even newer ones like Turflon + topramezone (Pylex).
• Sethoxydim (Bonide Grass Beater, etc.): Sethoxydim is an ingredient in some homeowner products that kills grasses but not most broadleaf plants. It’s commonly used to kill grassy weeds out of flower beds or around shrubs. It can injure Bermuda grass as well.

It’s worth mentioning that selective control of Bermuda is usually a slow process. Unlike glyphosate which browns it out in a couple weeks, the selective herbicides often only suppress Bermuda at first, especially if it’s well established. You often have to do multiple applications over a season or even year-after-year to finally see the Bermuda gone. It’s more of a “management” approach than a quick kill. The upside is your desirable plants or lawn fill in during that time and you (hopefully) don’t have big bare spots.

Pro Tip: For cool-season lawns (fescue, bluegrass) with Bermuda intrusion, one strategy is a season-long program: e.g., apply a combo like Pylex + Turflon in late summer for a few treatments, or Acclaim + Turflon in fall, then overseed in fall to let fescue fill in, and possibly hit any survivors in spring. This coordinated attack, plus mowing high and good lawn care, can drastically reduce Bermuda after a year or two. It requires commitment, but it’s how the pros often do it.

Always check which selective herbicide is safe for the plants you have. For example, Ornamec (fluazifop) is great in ornamental beds and fescue lawns, but it’s not safe on some grasses like ryegrass or bluegrass lawns; it would kill those too. Likewise, some products can’t be used around edible plants/veggies. Read the fine print to avoid collateral damage. If in doubt, consult an extension recommendation or a professional for the right product.

Method 5: Natural and Organic Herbicide Alternatives

Understandably, many people want to avoid harsh chemicals and seek a natural way to kill Bermuda grass. There are products and home remedies often touted as “organic weed killers,” so let’s address what those are and how they fare against Bermuda:

Vinegar

Household vinegar (5% acetic acid) or horticultural vinegar (20% acetic acid) is a common suggestion for weed control. Vinegar can indeed burn the leaves of Bermuda grass, especially the stronger horticultural kind. If you spray vinegar on a hot sunny day, you’ll likely see the Bermuda foliage turn brown and crispy within hours. However, vinegar is a contact herbicide; it does not move into the plant’s roots. Bermuda’s roots and rhizomes typically survive vinegar applications. The grass may appear dead, but often it’s just the top growth; new shoots can emerge from the unharmed roots a week or two later.

Additionally, vinegar is non-selective and can lower soil pH temporarily, so you have to be careful not to douse your nearby plants. In summary, vinegar might be okay for a quick knockdown of Bermuda in cracks or spots where you plan to follow up with something else, but it’s not a one-time cure for established Bermuda grass.

Boiling Water

Pouring boiling water will also kill or severely scorch any plant it touches. This can work for very localized issues, say a clump of Bermuda coming up between patio stones. If you consistently pour boiling water on a patch, you might eventually exhaust it. But like other methods, boiling water typically won’t reach deep rhizomes unless you literally cook the soil repeatedly. It’s a bit impractical for large areas (and dangerous to lug around pots of boiling water). Still, it’s a chemical-free tactic for spots where you just need to kill a little grass and don’t mind if it also kills everything else in that spot.

Salt

Some folks consider salt (sodium chloride) to kill weeds. Salt will indeed kill plants by drawing out water and essentially poisoning the soil. But using salt in your yard is generally a bad idea; it can ruin your soil structure and prevent anything from growing there for a long time. It’s not selective either. I would avoid salt except maybe in a last-resort situation on a gravel driveway or something far from any desirable plants.

Flame Weeding

Using a torch or flame weeder to burn Bermuda grass is another idea. Like boiling water, fire can burn off top growth effectively. However, Bermuda’s growing points are at or below ground level, so superficial flames might not kill the whole plant. And any surviving root will come back. Plus, there’s obvious fire risk and safety concerns. It might be useful to quickly clear dried Bermuda stolons along a driveway edge, but it won’t eradicate the problem fully.

Organic Herbicide Products

There are many OMRI-listed or “natural” weed killers on the market. They often contain ingredients like clove oil, citric acid, fatty acids, or ammoniated soaps. Examples: BurnOut (contains clove oil and citric acid) or Avenger (citrus oil). These work similarly to vinegar; they cause fast burn of above-ground growth by desiccating or “burning” the plant tissue. The OSU trials showed that while these natural products “provided a very temporary sense of control,” the bermudagrass nearly always grew back from the roots. They simply don’t penetrate to kill the rhizomes. I have used some for general weed control and they’re fine for annual weeds or young seedlings, but for Bermuda? Expect only temporary results.

Given all that, natural methods to kill Bermuda grass are largely about persistence. You might weaken it with vinegar or organic sprays, then immediately cover or dig it out. If you refuse to use synthetic herbicides, you certainly can still win the battle, but you’ll need to combine the non-chemical approaches (smothering, diligent digging, shading) and be prepared for a longer campaign. The extension experts often gently note that no organic product truly eradicates Bermuda’s roots; it usually “requires a chemical” to fully kill it. But you can suppress and manage it organically to a tolerable level with effort.

One compromise some gardeners do: use a targeted application of a less persistent herbicide like glyphosate to knock it down, then use organic methods to keep it out. Glyphosate doesn’t linger in the soil long, so your garden can still be “organic” moving forward after that intervention. Of course, the choice is personal, and I’m here to support whatever route you choose by providing the facts.

Preventing Bermuda Grass from Returning

After all the hard work of getting rid of Bermuda grass, the last thing you want is to watch it creep back in. Prevention is critical because Bermuda is a sneaky adversary that can re-enter your yard in various ways (from neighboring lawns, stray seeds, etc.). Here’s how to keep a Bermuda-free area protected:

Lawn Maintenance to Deter Bermuda

If you’ve cleaned Bermuda out of a lawn or are keeping it at bay, maintain that lawn in tip-top shape:

• Mow High and Often: As discussed, a taller mowing height (3–4 inches for fescue) shades soil and prevents any new Bermuda seedlings or stolons from getting light. Also, frequent mowing (at proper height) ensures that if any Bermuda does start growing, it gets cut before it can form seeds or long runners.
• Proper Feeding and Watering: Fertilize your lawn appropriately (usually fall for cool-season, summer for warm-season lawns) so the desirable grass is thick. Water deeply but infrequently for deep roots. A healthy lawn will outcompete a lot of invaders. Conversely, a weak, thin lawn is an open invitation for Bermuda to move in again.
• Watch for “Off-Color” Patches: In a cool-season lawn, Bermuda often reveals itself by going brown in the fall (dormancy) or looking lighter green in summer. If you see a spot that doesn’t match the rest of your lawn, inspect it. Early detection of a small Bermuda patch can allow you to dig it out or spot-treat it before it spreads widely.

Edging and Physical Barriers

As the saying goes, “good fences make good neighbors” – this applies to grass too! If your neighbor’s lawn is full of Bermuda or there’s wild Bermuda in an adjacent field, you might need a physical barrier at the boundary. Some options:

• Edging Materials: Install steel or heavy plastic edging 6–8 inches deep along the border. While Bermuda can jump or go under shallow barriers, a deeper barrier can slow it down significantly. It won’t stop roots that go deeper, but most spreading stolons are near the surface. This is especially useful between your flower bed and your Bermuda lawn area; it makes maintenance easier.

• Mow Strip or Trench: Create a bare soil or brick mow strip around the perimeter. A 6-inch wide trench or a paved edge means any Bermuda crossing it is exposed and easy to spot and kill. Essentially, you’re forcing the grass to reveal itself instead of sneaking underground unseen.
• Regular Edging Cuts: If you edge along sidewalks or beds, do it religiously (at least monthly growing season). Cutting the rhizomes at the border each time helps prevent them from creeping further. Think of it like cutting off reinforcements before they invade.

Keep in mind, barriers reduce spread but rarely eliminate it entirely, vigilance is still needed. Bermuda might still flower and drop seeds that blow into your area, or find a tiny crack under a fence line to invade. But barriers buy you time and make it easier to intercept.

Frequently Asked Questions (FAQs)

Q1: How do I permanently kill Bermuda grass?

A: Permanently killing Bermuda grass usually requires a systemic herbicide and multiple treatments. The most reliable method is to apply a glyphosate-based herbicide (which goes down to the roots) in late summer when Bermuda is actively growing, repeat the application after a few weeks, and then remove or till under the dead turf.

Q2: What kills Bermuda grass but not my lawn?

A: To kill Bermuda grass in a cool-season lawn (like fescue or bluegrass) without killing the good grass, use a selective herbicide labeled for that situation. Products containing fluazifop (Fusilade II) or fenoxaprop (Acclaim) can suppress/kill Bermuda in fescue with minimal harm to the fescue. Often these are used in combination with triclopyr (a broadleaf herbicide) for better results.

Q3: Does vinegar or boiling water kill Bermuda grass?

A: Household remedies like vinegar or boiling water will only kill the top growth of Bermuda grass, not the deep roots. Strong vinegar (acetic acid) can burn the leaves and you’ll see it turn brown. Boiling water will do the same on contact. However, Bermuda’s underground rhizomes usually survive these treatments and the grass can resprout.

Q4: How can I prevent Bermuda grass from spreading?

A: To prevent Bermuda grass from spreading into areas you don’t want it, maintain barriers and vigilance. Install deep edging or borders between Bermuda-infected areas and clean areas. Keep your lawn thick and healthy so Bermuda can’t easily infiltrate bare spots (in a fescue lawn, this means regular overseeding and feeding). Remove any stolons or sprigs immediately when you see them, don’t let them take root. Along fences or driveways, check for Bermuda runners creeping under or over and pull them out. In garden beds, a thick layer of mulch and even landscape fabric underneath can deter spread.

Q5: When is the best time to spray Bermuda grass with glyphosate?

Late summer or early fall is best. Apply glyphosate to actively growing plants with lots of leaf surface, allow regrowth, and spray again after 3–4 weeks. Avoid mowing for two to three weeks before treatment to maximize herbicide uptake.

Conclusion

Removing Bermuda grass isn’t easy, I won’t sugarcoat it. It’s often said that Bermuda grass can’t be controlled with a one-time effort; it requires a plan and perseverance. Hopefully this guide has given you a clear plan of attack and confidence that it can be done. Remember:

• Identify and understand the enemy: Knowing how Bermuda spreads (rhizomes, stolons, seeds) and why it’s tough helps you choose the right methods.
• Use multiple methods in combination: Dig, solarize, spray, mulch; layer these approaches for best results. One method by itself might not do it, but two or three together just might.
• Be patient and persistent: You may have to repeat treatments or keep areas covered for a season. Don’t give up if you see a few green shoots later – that’s normal. Just hit them again.
• Promote healthy desired plants: A strong lawn or dense garden planting is your long-term defense against Bermuda coming back.
• Stay vigilant: Once you’ve won the major battle, stay on guard at the borders and catch any resurgence early.

As an experienced gardener, I’ll add that it can be satisfying to outwit this “devil’s grass.” There’s nothing more rewarding than looking at a flower bed that was once choked with Bermuda and seeing it clean and blooming with your favorite plants. With the tips above, a bit of elbow grease, and the right timing, you’ll be well on your way to reclaiming your yard from Bermuda grass. Good luck, and happy gardening! You’ve got this!
