Tall Grass Weed With Seeds On Top

Having a difficult time identifying lawn weeds that look like grass? I've rounded up a list of common grass-like weeds to help you ID weeds in your lawn. Differentiating weeds from grass is important to treat the issue. How can you tell the difference? If you’ve noticed some weeds that look like wheat appearing all over your lawn, you might be wondering what they are. I’ll explain what they are in this post.

List of Common Weeds That Look Like Grass

You’ve been working hard on cultivating the perfectly manicured lawn, taking all the necessary steps to plant seed or sod, fertilize, and mow appropriately. Despite your best efforts, there seem to be patches of your lawn that don’t match the rest. There are some common weeds that look like grass which tend to blend in with a lawn and thus can be more difficult to identify and target when compared to the average dandelion.

In this article I’ll help you identify these grass-like weeds and offer advice for how to combat and eliminate them from your lawn.

Common Weeds That Look Like Grass

Crabgrass

Also known as finger grasses, crabgrass can be an invasive type of weed that looks very much like grass.

It often sprouts in smaller patches throughout your lawn and has a distinctly coarse texture compared to the rest of your lawn. Thankfully, crabgrass is an annual plant so it only survives for the season and then dies.

That said, it spreads quickly, and because of its thick blades and lateral growth, it can quickly do permanent damage to your lawn by crowding out and smothering the grass surrounding it.

This is why it’s important to be vigilant and act right away if you see crabrass in your lawn.

The best way to get rid of crabgrass is by preventing its germination using a pre-emergent herbicide that can be commonly found in combination with fertilizer that you can spread in early spring.

Once crabgrass has germinated, the best way to get rid of it is by pulling it or using a direct herbicide.

Thankfully, crabgrass is not perennial so it is relatively easy to get rid of it with some diligence, and once you improve your lawn the canopy will be too dense for crabgrass to grow.

Wild garlic and onion

While it looks very much like a tall grass, wild onion and wild garlic are very fragrant and thus these grass-like weeds are pretty unmistakable once you get close enough to smell them.

If you finish mowing and it smells like you’ve been making pasta sauce, there’s a good chance you have some wild onion and/or wild garlic hiding in your lawn.

Wild onion and wild garlic also become noticeable as they grow faster than regular grass and quickly surpass the height of your lawn.

They grow in clumps, so if you have them, the rate of growth and growth habit make them pretty easy to identify.

For those who love garlic and onion as an addition to many dishes, this may be more of a fortuitous find (transplant them!). However, even the biggest garlic fans probably don’t want a swath of it in the middle of their lawn.

Thankfully, these weeds that resemble grass tend to only grow in early spring and late fall, becoming dormant in the summer season.

To remove them from your yard, dig them up (I recommend transferring them to a pot or herb garden) – just make sure to get bulb and all, or they’ll come back.

Herbicides will also work to kill wild garlic and onion, just make sure to check the label of the product your purchase to ensure that wild garlic and onion are included in the list of weeds it treats.

Nutsedge

Before it matures and blooms, nutsedge can look much like a tall grass.

Unlike crabgrass, Nutsedge is a perennial weed that can be quite invasive and difficult to get under control due to its hardy root systems.

It can also be spread throughout your lawn (or from a neighbor’s lawn) both by airborne seeds as well as underground rhizomes or tubers. It will continue to come back year after year unless you get it under control.

Sort of like fight club, the first rule of Nutsedge is not to pull Nutsedge.

If you try to combat it by pulling it, you’re likely to leave behind tubers or rhizomes that will end up sprouting.

One of the most effective ways to prevent Nutsedge is to grow a thick and hardy lawn that will crowd out Nutsedge, and prevent this invasive grass-like weed from being able to properly root and grow those rhizomes and tubers that make it so invasive.

But if you have it, recommending that you hop in your time machine and take steps to prevent it doesn’t help you.

If you have Nutsedge in your lawn, there are specific herbicides that can be applied directly to the base of Nutsedge to kill the entire plant including the underground components, and while I always recommend an organic approach when I can, in this case this will be your best course of action.

Common couch

Another common weed that looks like grass is couch grass or common couch.

Sometimes referred to as quack grass, this is another invasive species that is hardy and can propagate quickly in your lawn via rhizomes as part of a complex and fibrous root system.

This makes it hard to pull in its entirety.

It also spreads via airborne seeds, thus being able to travel longer distances and quickly find a home in thin lawns.

Similar to many of the other grass-like weeds, prevention by crowding out seeds is the most effective way to prevent these species from invading, which is why proper and regular lawn maintenance and improvement are always my best defense against lawn weeds.

Green foxtail

This weed gets its name from the appearance of the mature heads that bloom on these grass-like stalks. The heads look like small fuzzy foxtails!

They can grow anywhere from 10cm to 100cm tall and are very common in prairies and meadows. Despite its cute name, it is an invasive species that can be quite problematic, especially for farmers, and a nuisance to lawn owners everywhere.

This hardy annual plant with hundreds of seeds per foxtail plume spreads easily, as these seeds can travel great distances with enough wind.

Despite how hardy these lawn weeds are once established, they are quite a picky species when it comes to germinating. They prefer moist soil and are easily crowded out by densely planted lawns or fields.

Green Foxtail also prefers warmer soil in the range of 15 to 35 degrees Celsius (59-95 degrees Fahrenheit), but this weed can germinate at any point in the season as long as conditions are favorable.

Like most lawn weeds, Green Foxtail can be controlled with some herbicidal solutions, but the best way to prevent this invasive species is by crowding it out with a thick, healthy lawn.

Smooth bromegrass

Another hardy perennial, Smooth Bromegrass, is highly adaptable and it is able to grow even in cold conditions and survive for quite a long time once established.

Like Nutsedge, Bromegrass can grow rhizomes underground through intricate root systems, which will help it to spread across your lawn quickly … especially if your lawn is thin.

These qualities make it an invasive species that can easily get out of control.

However, Bromegrass serves an important purposes as hay and grazing fields for livestock and it can also help to prevent soil erosion due to this strong root system.

Despite these qualities, most homeowners probably don’t want it in their lawn. To control and eliminate Smooth Bromegrass in your lawn, I recommend mowing it down low and attempting to crowd it out with a thick, healthy lawn canopy. In a worse-case scenario, you should opt for an application of herbicide designed to target this grass-like weed.

Slender rush

Also known as “poverty rush” or “path rush”, this grass-like perennial tends to grow in clumps, which is similar to crabgrass.

It is propagated by above-ground seeds as well as below-ground tubers that form with the help of the root system. The deeper root structure with rhizome propagation makes slender rush a particularly invasive species to get under control in lawns, because it can still be present even if you can’t necessarily see it yet.

Herbicides are not usually an effective way to control slender rush.

Manual weed management tends to be the most effective way of dealing with this invasive weed that looks like grass. This can involve pulling weeds by hand. Do so carefully, and be sure to get the root system as well.

The other options is a mowing routine that doesn’t allow for the plant to mature and spread seeds above ground.

Tall fescue

You’ve likely heard this species discussed in the context of a grass, however it is an invasive perennial that has characteristics of a weed, particularly if your lawn is primarily a different type of turfgrass.

Similar to some of the other species discussed above, tall fescue has the ability to propagate via rhizomes underneath the ground. It is highly drought resistant, and in areas where it has been planted it has often taken over, crowding out other species of grass.

If you wanted to get rid of tall fescue grass that has run wild in your yard, you’d probably have to solarize it. Solarizing involves covering up large areas of grass to deprive it of sunlight and also increase the heat underneath the tarp so that it kills everything underneath.

Herbicides could also be used, but it would take a large amount which could get costly and be harmful to the environment, so I recommend solarizing tall fescue.

Restoring Lawn and Order

It’s interesting to compare various grass-like weeds and perennials that are less desirable than the perfectly manicured lawn.

Eliminating Weeds That Look Like Grass

Careful selection of grass species is important in establishing a lawn.

It’s also possible to crowd out many of these invasive species by planting additional grass seed seasonally (overseeding) to create a thick and lush lawn.

Pre-emergent methods can also be an effective backup method of prevention, and using a pre-emergent every spring for several years as you overseed, fertilize, and use proper irrigation to improve your lawn can help to create that thick, dense lawn canopy that will prevent weeds from taking root in your grass.

Need help with naming an invasive looking weed that has leaves that look like a rocket, long thick body with small wings. It’s overtaking my raised beds. I have a photo.

I’ll see if I recognize it! Email me a photo (my first name @ lawnchick.com)

Hello Sarah,
I have a few new spring weed grasses popping up that I didn’t see last year. Are you ok with sending the pics to your email for your opinion?

Thank you
Brian

Sure, Brian – I may not get back to you until this weekend but I’ll take a look as soon as I can!

Hi Sarah!
I just discovered your website/posts while researching ‘weeds that look like grass’. I breed, raise and train springers which are flushing dogs. Recently, I came back from an excursion and one of my springers got a ‘grass thorn’ stuck in her paw. I always check for these things but somehow I missed this one. Nasty little thing but it was removed and after treatment, my dog was right-as-rain!
I was researching lawns / grasses etc. as I’m planning to re-do my yard, making it more ‘dog friendly’. I was shocked to learn that Tall Fescue grass is considered an invasive weed on your website. This was the grass that was ‘highly recommended’ for those who have dogs. As I’m not keen on putting anything in that resembles bamboo in it’s underground system (I’ve had a 30 yr battle with this horrific stuff), can you suggest anything else? Any information you may provide would be greatly appreciated.

Thanks for the comment. Springers are great dogs!

There are a LOT of different types of fescue, and as with any grass … what some consider a weed, others consider the foundation of a beautiful lawn. If you like the characteristics of fescue, I’d recommend you consider Turf Type Tall Fescue. It’s an improved variety designed for lawns and something I think you’ll be really happy with if you’re determined to go with a single type of grass for your yard.

You can read more about all of your options for Fescue here, and I have a comparison of TTTF and Kentucky Bluegrass which you may find interesting here.

You also may be interested in my article about how to grow grass with dogs that love to destroy it, which has some good tips on maintaining your lawn with four-legged friends. You can check that one out here.

Finally, I’d suggest that it might be a good idea to get a blend of grass seed, with whatever you settle on as the primary seed. I’m in New England and my lawn is a mix of Perennial Ryegrass, Kentucky Bluegrass, and a few different fescues. Getting a seed blend that’s made for your area will give you good results, and provide good coverage in different areas of your lawn (full sun, part shade, shade, wet, dry, etc.). I think that’s easier to maintain than having to baby a single type of grass on parts of your property where growing conditions might not be ideal. With a blend of seed you allow different grasses to become dominant where the conditions are best suited for them, and your whole lawn looks and feels healthier.

Hope this helps – good luck!

Hi Sarah! Thank you so very much for all your help! This is the most information I have ever received! I love the idea of mixing grass seed … this could be a very good solution. My lawn is not very big … I have four ESS and of course they have worn paths to their various ‘barking stations’ ! The lawn is basically sunny and has thrived well. But, over time, some of the grass has worn despite my best efforts at ‘re-seeding’. I was relieved to learn that there are many types of Tall Fescue Grass. I would really like to see some great photos of lawns using this variety: google just doesn’t cut it!
Again, thanks so much Sarah. I live in BC., Canada so our climate is quite different from yours. Fortunately, living in the southern part (coast), we experience quite a mild climate, lots of rain in the winter with very little snow and our summer highs almost never reach higher than 34C. I will take all your suggestions under advisement and begin my research pronto!

You bet, Sharleen! Good luck and have fun with your project!

I have an area of lawn that has really compact soil, where a portion of the section gets scorching sun and the remainder is covered in shade. This year, I’ve tried growing Bermuda grass, but that is only taking somewhat in the sunny area. It has been so bad for so long that I’m now researching “weeds that look like lawns” that I can plant in this area and just be done with it! We are in central Virginia and have hot/humid summers and still some winter.

The transition zone can be tough for grass for some of the reasons you’ve outlined here. I’d try the Combat Extreme Transition Zone seed blend from Outside Pride. I’d plant it in September to give it the best chance of success so it can establish itself as things start to cool down in your area and it can build roots and come back strong and healthy for next season. The Outside Pride website has a calculator specific to this seed that will tell you exactly how much you’ll need to order and spread (I’d go a bit heavy, but that’s me). Here’s a link to an article with some resources to measure the lawn area you plan to re-seed so you’ll know exactly how much you need. I’d give this one (or one like it) a try before you throw in the towel. You need a good blend that can take sun and shade, and a fescue blend should be best for you as it’ll have the deep roots needed to withstand your summer heat.

Do you know what species prefer weeds to monocultures? All pollinators! Please consider why you feel you need a vast monoculture of grass in the first place.

Totally agree with you – I have huge perennial beds filled with native, pollinator-friendly plants that are in flower from spring through late fall for exactly this reason. I’m of the mindset that you can create a beautiful lawn for your family to enjoy while also supporting pollinators.

I have quite a few resources on this site that address this subject, as well. Here are a couple you may enjoy:

Thanks for your comment!

I just happened upon your website, Sarah. Thank you for sharing your knowledge with those of us who want weeds diminished in our lawns. Is there a specific herbicide that we should consider in dealing with nutsedge? Thanks for your attention to this matter. Frank

I’d try the Ortho Nutsedge product. It’s probably something that’s available locally, but you can also get it online (Amazon link). I like it because it comes ready-to-use in a hose-end sprayer. For those of us who don’t really like mixing herbicides, that’s a benefit.

As with any herbicide, I recommend testing it out in a small area before you spray it all over your lawn just to be sure it’s effective and that it isn’t going to kill your turfgrass in addition to the Nutsedge and cause a big headache for you.

We’re trying to identify a grass-like plant in our lawn (we’re in New Hampshire). I think it looks like a flat circle of knives. Pretty, but not the nice soft grass you’d want to walk through barefoot.

We have a picture that we can send.

I’ll see if I recognize it! Email me a photo (my first name @ lawnchick.com)

10 Weeds That Look Like Grass

Mother Nature can be a clever mistress, indeed. She can be so clever that she can disguise a variety of different common weeds that look like desirable grasses.

An invasion of such a grassy weed is insidious. It doesn’t appear to be a serious problem for your lawn until it’s already become a serious problem.

These weeds hide in plain sight and can be easily overlooked if you don’t know what you’re looking for.

That’s what this article is all about. We are going to provide you with a list of weeds that look like grass. You’ll discover how to identify each grassy weed and learn some different control methods for each one.

So, before these common weeds that look like common lawn grasses become an issue, let’s dive in and take a look.

1. Annual Bluegrass (Poa annua)

What it Looks Like

Annual bluegrass (Poa annua) is one of the most commonly misidentified weed grasses. It is a close relative of the desirable cold-season Kentucky bluegrass.

As with all members of the Poa genus, annual bluegrass has canoe-shaped tips on its grass blades. Because they mimic the shape of other Poa species, the best way to identify these grassy weeds is to look for their brighter and lighter green color.

Annual bluegrass also has a long ligule, or membrane, that connects that leaf blade to the base of the stem.

Annual bluegrass is also a cold-season weed grass. They tend to congregate in shady areas with excess moisture. The heat and light from the sun will dry these grassy weeds out and leave bare patches in your yard.

Control Methods

Annual bluegrass can be treated with both pre-emergent and post-emergent herbicides. However, the best way to ensure that you don’t have it hiding on your lawn is to create a habitat not suitable for its growth.

If you have areas of your yard that are shaded, open them up by trimming back the trees or shrubs that provide the shade. For moist areas, ensure that the soil isn’t compacted and is properly draining. These two prevention methods should do your grass justice and keep annual bluegrass at bay.

2. Crabgrass (Digitaria sanguinalis and Digitaria ischaemum)

What it Looks Like

If you’ve not heard of crabgrass, then you’re not spending enough time outside. Because these grassy weeds are everywhere. Digitaria sanguinalis (also called large crabgrass) is predominantly found in the northern part of the country, and Digitaria ischaemum (also called smooth crabgrass) is the crabgrass species that dominates the southern part.

But crabgrass is crabgrass. And none of it’s good. This grassy weed makes its home on unhealthy yards. So if your lawn is under-watered, under-fed, and poorly drained, then you’re probably going to have a problem with crabgrass.

See also  Smart Weed Seed

Crabgrass plants are annual weeds that will die off each year. That may sound like good news until you hear that each crabgrass plant is capable of producing more than 150,000 seeds that can germinate every spring.

Crabgrass grows in clumps on your lawn. While it does look similar to normal grasses, it has a much thicker growth habit and is altogether an unattractive eyesore on your lawn. If the seeds do germinate and grow unchecked, the blades can grow as long as 2 feet. Crabgrass is generally a lighter green than most desirable lawn grasses. Once its root system is established, it spreads quickly and aggressively across your lawn.

Control Methods

Just like annual bluegrass, you can get rid of crabgrass with one of many selective pre-emergent herbicides to prevent the seemingly countless seeds from germinating. If you’re too late for that, a selective post-emergent herbicide will also clear up the problem. However, your best bet if the seeds have already germinated is to recognize and pull the crabgrass plants before they’re old enough to go to seed.

The best defense, however, is a good offense. And a good offense, in this case, is ensuring that your lawn is healthy and thick. Take care to ensure proper fertlization, watering, and drainage on your property. This will keep your desirable grass too thick and healthy for crabgrass to invade.

3. Yellow Nutsedge (Cyperus esculentus)

What it Looks Like

Yellow nutsedge is a perennial weed that can attack your lawn from above the soil and below. Seeds can be spread through the air from above the soil level and through its rhizomes, or tubers, below the soil’s surface.

The fact that it’s a perennial weed that will reappear each growing season only complicates matters further.

When yellow nutsedge is young, it will have light green colored grass blades. As it ages, the grass blades will become a deeper green. This change in color can make it hard to identify amongst your desirable lawn grass.

Yellow nutsedge is best identified by looking at its root system. On its roots, there will be nut-like tubers growing from them. These tubers give the grassy weed its name.

Control Methods

The best plan of action for controlling yellow nutsedge is to keep your lawn lush and healthy. A healthy lawn will do its own work and prevent nutsedge from having a place to invade. So be sure to do the upkeep using proper maintenance practices, and you should be fine.

Since yellow nutsedge is a perennial grassy weed, once it shows up on your lawn, the best way of getting rid of it is a heavy dose of post-emergent herbicide.

Pulling the weeds may cause you more problems because leaving the smallest piece of these plants in the soil guarantees that they will regenerate and make a repeat appearance on your lawn. If you decide to go this route, ensure that you remove every single fiber of the yellow nutsedge from the ground.

4. Green Foxtail (Setaria viridis)

What it Looks Like

Green foxtail earns its name because, once it is fully grown, a piece of the plant resembles the tail of a fox. This piece that resembles a fox tail is a seedhead that can produce hundreds of problematic seeds that can spread through your lawn and garden.

Green foxtail is an annual grassy weed that will require the germination and growth of brand new plants every year.

Identification can be tough before the plant grows its seedhead. Its blades are a normal green color and don’t have a remarkably different shape than most desirable lawn grasses. Its growth habit is normal as well. So this one can be tough to spot.

Control Methods

Since it’s an annual weed, you can control green foxtail by pulling it out. Preferably, you’ll have it removed before it goes to seed. But, as you already know, this can be a difficult task because it looks so similar to your grass before that point.

If you find that green foxtail has already gone to seed, you can pull the plant from the soil and use a pre-emergent herbicide to keep the green foxtail’s seeds from germinating in the spring.

If the invasion is too great to pull all of the grassy weed out, you can use a selective post-emergent herbicide to kill it off. You’ll still need to treat the ground with a pre-emergent herbicide at some point before the seeds begin to germinate when the weather warms up.

5. Creeping Bentgrass (Agrostis stolonifera)

What it Looks Like

Creeping bentgrass is often planted intentionally. But this intentional planting is usually relegated to the fairways and putting greens on manicured golf courses and not on your yard.

Creeping bentgrass can spread aggressively in your grass and garden through its stolons.

Creeping bentgrass will appear in light green patches in your grass. Its blades are generally finer and thinner than most desirable grasses. If you allow creeping bentgrass to grow taller than 1 inch, it will take on a puffed-up or swollen appearance.

Cool-season creeping bentgrass is averse to excessive heat and will turn brown quickly at even slight elevations in temperature.

Control Methods

Because creeping bentgrass propagates and spreads through its stolons beneath the soil’s surface, one plan of attack is to use selective herbicides on this hardy perennial plant. An herbicide containing glyphosate is your best bet. However, this may only work if you catch these lawn weeds very early in their life cycle.

Creeping bentgrass is often more widespread than it may seem. This is due to it spreading underground through its stolons. On average, if you have a patch of creeping bentgrass with a diameter of 1 foot, you actually have a mix of the grassy weed and your desirable grass that extends three times that diameter. This makes spot-treating creeping bentgrass very difficult.

Unfortunately, the nature of these weeds makes them very difficult to completely eradicate once they are established. So, you’re either going to have to start over by removing all the grass entirely and reseeding or start promoting the growth of creeping bentgrass on your property.

To promote creeping bentgrass, you’ll need to shift your focus from soil fertility and nutrition to pest control. Because pests are one of this weed’s primary afflictions.

6. Common Couch (Elymus repens)

What it Looks Like

Common couch is a hardy perennial grassy weed that also goes by couchgrass and quackgrass. These weeds are equally at home in shade and sun.

Common couch spreads through both its underground rhizomes and its airborne seeds. Once it is established, its root system becomes exceedingly difficult to remove completely. So, it’s best if you can catch it early.

Common couch has a coarse texture and will appear on your lawn in patches. It’s blue-green color can be hard to distinguish amongst some desirable grasses.

The blades of these grassy weeds look similar to fingers. Their growth habit wraps these finger-like blades around the stem at the base of the plant.

Control Methods

If it is allowed to grow unchecked, common couch will take over your lawn in no time. It makes its home on areas that are thinned or bare. So, an unhealthy lawn makes the perfect victim for these weeds.

Whenever you come across common couch in your lawn or garden, you can pull it up by hand. But, if you do, you need to ensure that every piece of the plant is removed from the soil. Otherwise, you’re destined for another visit as soon as it can regenerate.

Chemical control will require both pre-emergent and post-emergent herbicides because it spreads underground through its rhizomes. So you have to ensure that the hardy root system is dead to prevent its propagation.

The best defense against common couch (and this feels like it’s becoming a theme) is a healthy, vibrant, and thick lawn. It will outgrow the weeds, and they won’t have any space to invade.

7. Smooth Bromegrass (Bromus inermis)

What it Looks Like

Just like couchgrass, smooth bromegrass is a perennial weed that can spread through either rhizomes or seeds. It also has a robust root system that will be difficult to get rid of once it becomes established in your lawn.

Smooth bromegrass can grow to heights of over 7 feet. Its blades, or leaves, grow to between 8 inches and 2 feet long. The blades hang down in a drooping manner. The blades are covered on both the upper and lower surfaces by fine hairs.

This weed’s color ranges from a light to a normal shade of green. The upper portions of the blades can be lighter in color because of their length if growing conditions are poor.

Control Methods

Fortunately, you can control smooth bromegrass by keeping it cut short with your mower or weedeater. Keeping it short will allow your desirable grass to crowd it out eventually, and you won’t have to resort to any chemical herbicides.

However, if the weeds have spread out and established themselves, you’ll need to use some strong pre-emergent and post-emergent herbicides to quell the invasion. Use an herbicide with glyphosate for the best results.

8. Carpetgrass (Axonopus compresus and Axonopus affinis)

What it Looks Like

These weeds share the same genus and have similar physical traits, so they’re lumped together under one name. Carpetgrass is a perennial weed that can grow to heights of a foot or more. It will appear on your lawn in very thick mats that are shaded a normal green color.

In the summer, they will produce seed heads that look very similar to those of crabgrass. The seed heads will be taller than the rest of the plant.

Carpetgrass prefers acidic soil with high moisture content. You will probably find them congregating and growing in shady areas that do not receive adequate sunlight. This allows the moisture levels to build up in the soil.

Control Methods

One good thing about carpetgrass is that you can control it through natural methods. All you have to do is raise the pH level of the soil. You can do this by adding lime or salt mixed with a gallon of water. One of these two should do the trick.

Of course, if you catch it early enough, you can pull it from the earth. However, since it is a perennial weed, you’ll need to ensure that you remove every last piece of it from the ground.

9. Tall Fescue (Festuca arundinacea)

What it Looks Like

This may be confusing because tall fescue is used as a desirable grass on some lawns. However, much like creeping bentgrass, it can show up without an invitation and take over your lawn. Ironically, the very things that make this such a desirable grass are also the things that make it a worthy opponent in your yard.

Tall fescue has distinct blades or leaves. The leaves of tall fescue are thick and broad. They have pronounced veins running the length of the blades, and this gives them a coarse texture. The blades are colored bright green, and the lower surface is a lighter green than the upper surface.

Control Methods

When it comes to tall fescue, I have some good news and some bad news. The bad news is that it is an extremely hardy plant that is very drought resistant. Once it shows up in your grass, it can be challenging to remove it completely.

It spreads through underground rhizomes, so its initial damage assessment may be underestimated. It can be spread further than it appears at first.

The good news is that you can beat tall fescue with natural means. Solarization is the best technique to use. Cover the weeds up with black plastic, newspaper, a tarp, or cardboard and let the heat, combined with a lack of sunlight and oxygen, suffocate the invasion out of your yard.

10. Johnsongrass (Sorghum halepense)

What it Looks Like

Johnsongrass is a perennial weed that is relatively easy to identify and control, which is a different story than the rest of the perennial weeds in this article.

When johnsongrass is in its early stages of life, it resembles the seedlings of the corn plant we all know and love. Left to grow unchecked, it can reach heights of over 7 feet.

Its seed head will start out green and then transition to a purplish maroon color.

As johnsongrass matures on your lawn, you’ll be able to pick it out because its leaves will become up to an inch thick and have a distinct white vein running down the middle of each blade.

Control Methods

There’s an easy way to control it and a hard, labor-intensive way to control it. The easy way is to cover the entire plant with highly concentrated vinegar. Be careful not to spray anything you don’t want to kill because vinegar is non-selective.

The hard, labor-intensive control method is used for larger johnsongrass invasions. It spreads through its rhizomes under the soil along with its seeds. So, to kill the johnsongrass, you’ll need to expose those rhizomes to the elements by using a tiller to cultivate the earth containing them. Do this later in the fall and expose the rhizomes to the cold winter temperatures, and they won’t be making a second appearance in the spring.

Weeds That Look Like Wheat in Lawns

What image comes to mind when you hear the word “wheat”? For me, it’s The Gladiator movie as Maximus runs his hand through the wheat fields on his return home. Epically cool in the movie, not so cool when it’s happening in your front yard. Especially when you learn that this is probably not even true wheat, but weeds that look like wheat, and often with detrimental side effects to your lawn.

Most Common Weeds That Look Like Wheat

When you think of a weed that looks like wheat, it usually means that it has grassy leaves with an inflorescence or spiked seed head, and that is most probably the part of the plant that you are associating with wheat. Common examples are Foxtail grasses, Wild barley, Couch grass, Fingergrass, and Barnyard grass.

A Closer Look At Lawn Weeds That Look Like Wheat

Unfortunately, these next few copycat species that look a lot like wheat, are mostly invasive and can crowd out and suffocate your lawn grass. Although these look like they are meant to be growing in your garden at first glance, they are actually detrimental to your lawn’s overall health.

1) Giant Foxtail (Setaria faberi)

Giant Foxtail is characterized by leaves that have hairs on their upper surface but nothing on the leaf sheath. Its inflorescence is a fuzzy panicle resembling a foxtail, hence the name, that is held up on a smooth erect stem. This plant can reach 16 inches in overall height.

It is an invasive summer annual with a clump-forming growth habit. Originally from Asia and mistakenly introduced to America in the 1920s when it was mixed in with other food grain crops, it thrives in fertile soil. Other similar varieties are Foxtail millet, yellow foxtail, and green foxtail.

2) Wild Barley (Hordeum spontaneum)

Wild barley is an annual that grows throughout winter and seeds in spring. If you can identify it and keep it mowed short it won’t become a recurring problem as it has a quick life cycle and can be cut consistently to prevent it from forming seeds. The long ”hairs” on the seedheads can cause irritation to animals’ eyes, skin, gums and get tangled in their coats, so this is not a pet-friendly weed to have growing in your yard.

3) Quackgrass/Couch grass (Elytrigia repens)

Quackgrass is a cold-season invasive perennial. It has rhizomes that spread underground and can split into separate clumps. This means it spreads fast and is very hard to get rid of.

If you notice fast-growing clumps standing taller than your lawn, investigate the possibility of quackgrass. To positively identify it, look at the base of its stem, where the leaf starts, for two clasping finger-like projections that can be found, called auricles. Other than suffocating your beautiful lawn it does not pose a health risk to either you or your pets.

4) Feather Finger Grass (Chloris virgata)

Generally accepted to be native to America, it easily establishes itself as a weed in areas where it is not necessarily welcome. It aggressively invades bare and disturbed patches of ground and spreads easily along roadsides. It is a common weed in cultivated crops such as alfalfa, maize, and sorghum.

5) Barnyard Grass or Junglerice (Echinochloa colona)

Originally from Asia, this annual invasive grass has distinctive reddish-purple stalks bearing seed heads at the top. It grows by branching out from its base. It can commonly be found in grain crops, gardens, waterways, roadsides, or any other area when it can sneak in and establish itself. The grass’s upright panicles are green, often with a purple tinge, and the tip bends over when mature. Neatly 4-rowed racemes are characteristic.

It is found growing predominantly in damp, fertile soils and can withstand seasonal flooding. It grows in more tropical climates such as South Florida, Texas, and in South-Eastern California. The grass begins flowering at 3-4 weeks and reaches 2m in height, so don’t blink or it will be taking over your yard.

So What Problems Can Grassy Weeds Cause?

I am sure that many of you have seen these weeds growing in your lawn and wondered: Why not just leave them? Is this really something that should be causing me to panic?

They generally grow taller than grasses that have been specifically chosen as a lawn grass. This means your lawn will end up with uneven tuffs that need to be mowed more regularly. They are also typically hairy and have rough seed heads, getting caught in pets’ fur, causing skin irritation, and generally just not resulting in a lush, soft lawn that you want to walk over barefoot (there’s truly no better feeling than this!).

Removal Suggestions

Anything you use to kill grassy weeds will generally kill your lawn too. This makes getting rid of this particular weed type that much harder. You should either spray them with a post-emergent weedicide or pull them out, making sure you get all the roots too. The best method for application would be spot treatment with a paintbrush or an accurate jet spray, as you don’t want to kill your lawn grass with any weedicide drift.

Some Lawn Grasses Have a Wheat-Like Appearance Too

Some lawn grasses form wheat-like seed heads too and they aren’t bad news at all. Examples include Perennial ryegrass, Tall Fescue, and Kentucky Bluegrass. They are all cool-season perennial types of grass that originated from Europe and North Asia.

They are commonly used as turf grasses all year round in the cooler northern states, or as winter cover in the warmer southern states. These grasses are usually seeded over summer grasses, like Bermuda, which goes dormant in winter. This keeps the lawn looking green through the cooler winter months.

When they go to seed they have an erect panicle seed head, and although they are much smaller than those of wheat, there are similarities in their formation. Most people keep their lawns nice and short with regular mowing and so you may never notice the grass forming tiny wheat-like seed heads. But don’t be alarmed if you miss a few mowing sessions, let your lawn grow longer and seed these seed heads. It’s not a bad sign.

Summary

Like with most things, the best form of defense against lawn weeds is a good offense. In this case a thriving, healthy lawn. Any bare spots, or where the grass is growing sparsely, allows for weed seeds to settle and sprout.

With the correct watering and mowing schedule, your lawn should form a healthy dense mat that doesn’t allow for invasive grassy weeds to establish. However, if you see a tuft of grass growing taller than the rest of your lawn, or a slightly different color to it, or if you see it starting to form a wheat-like seed head, don’t hesitate to grab it and pull it out before it has the chance to reseed.

About Tom Greene

I’ve always had a keen interest in lawn care as long as I can remember. Friends used to call me the “lawn mower guru” (hence the site name), but I’m anything but. I just enjoy cutting my lawn and spending time outdoors. I also love the well-deserved doughnuts and coffee afterward!
