Weeds In Your Lawn It May Be Quackgrass
This cartoonish sounding weed has recently been spotted in Cleveland and Columbus yards this spring. Often mistaken for crabgrass quackgrass is a perennial grass that looks very similar, with thin hollow stems and fat, hairy blades. In this article, we’ll take a look at what it is, what causes it, and most importantly, how to get rid of it.
What’s Quackgrass?
Quackgrass is a perennial weed that has been in America for hundreds of years. Like other perennials, quackgrass has a strong, deep root system with rhizomes that if split, can grow into separate plants. This quick spreading weed can take over a lawn very quickly and because most of the plant/weed is below the surface, it is very hard to control.
What Causes Quackgrass to Grow in Lawns?
Quackgrass seeds are a tasty treat for small birds, such as sparrows. Often these birds lose the seeds in your lawn, causing the weed to grow. Additionally, straw bales often contain quackgrass seeds that can get into your lawn.
Once one plant grows, it often spreads with a little help from us. When quackgrass goes to seed, mowing the lawn often spreads the seed further causing more plants, further complicating the problem.

Choking Out Quack Grass
Quack grass does have tremendous competitive power in terms of nutrient absorption. However, for your information, this will only happen if the competing grass is not active enough, but if you can raise the vigor of the lawn to fight back, then this problem can be solved.
The only way is to increase soil fertility. Try using a nitrogen fertilizer of 0.25 to 0.5 pounds per 1000 feet of soil. Do this twice a week during the growing season. When summer comes, stop this process first.
Afterward, try to observe the progress in the following season. If this program carried out properly, the weeds have a smaller structure than before. Try to do this process again in the next growing season until the unwanted plants are gone.

How Do You Apply This Quackgrass Killer
If you have an area that you want nothing to grow in at all like your steps or your driveway, you can apply this weed killer with a spray bottle. But, if you have an area that you have other growing things in like your lawn or your garden, you will want to apply it with a paintbrush. That way, it wont kill the other plants. Eventually, the rain will wash away the vinegar and dish soap and the area will be clear to grow in again.
Quackgrass doesnt respond well to a selective weed killer. You will need to use a weed killer recipe that kills ALL weeds in order to deal with it. Then, when its dead you must dig up the rhizomes or it will simply come back again.

Make Sure Youre Dealing With Quackgrass
Quack grass plants require a specific approach when you set out to eliminate weeds from your lawn. However, they often blend in with desirable grasses and can be difficult to spot until they mature and push past the other grasses.
If you have a sharp eye, though, you can identify new Quackgrass and prevent it from taking over your landscape. Quackgrass looks like a few other kinds of grass such as ryegrass, with thin, pale green leaves and spiky auricles. But, unlike similar-looking grasses, Quackgrass also has rhizomes, which produce thousands of new plants over a year.
The two kinds of grass often grow around each other, which is one reason why using mulch produced from ryegrass is risky and can introduce Quackgrass to your lawn. When you locate a suspicious-looking grass plant and see rhizomes, youve probably got Quackgrass.
Controlling Quack Grassy By Boiling Water
Even if you do not completely kill it, you can at least reduce the growth. One way to do this is to pour boiling water over the area you want to clean.
This method will help damage the living cells that are affected so that they dry out and possibly die, but be careful doing it because it can kill other organisms in the soil.

Douse With Sodium Hydroxide
Salt has been used since ancient times especially during war to poison the fields of the enemy. Salt is very toxic to plants and can effectively kill weeds such as crabgrass and quackgrasses. The major problem is that it doesnt discriminate. It will kill your good plants and grass as well.
Form a solution of sodium hydroxide, cover the nearby grass and plants that you dont want to affect. Use a spray-can to spray the sodium hydroxide solution directly onto the leaves of the quackgrass to kill it.
Vinegar is very potent at managing quackgrass and other weeds growing in your lawn. While there are other alternatives to vinegar as a weed killer, it is far much better than most of the techniques that try to compete. You should only master how to formulate it correctly including how to make the right proportions to achieve a better result.

How To Use This Homemade Weed Killer
Avoid saturating the grass and flowers with this quack grass killer. You can use this weed killer around grass and flowers but do not apply directly to them. It may burn the grass/flowers.

Check the forecast for rain. This mixture does best when it has the chance to sit on the weeds for 24 hours.
After 24-48 hours, your weeds will become dark and shriveled up.
Dig up the rhizomes to be sure they dont come back next year.

Manually Remove The Quackgrass
Brandon warns that one of your only options to get rid of quackgrass is to pull it out by hand. When manually removing the weed, you should try to pull as much of the root out of the soil as possible to destroy the deep-rooted systems.
However, while pulling out your quackgrass is an option, Professor Richard VanVranken warns that this process comes with its challenges.
If the quackgrass is in a very small area of turf, or especially in a tilled vegetable garden, one could dig out a few small clumps, carefully avoiding breaking any of the underground stems as much as possible, Richard says. He adds that you should remove any new sprouts if any broken-off rhizomes do regenerate.
Its to distinguish new young quackgrass sprouts amid the turf grasses, so thats not going to be easy, the professor warns. Depending on the size of the vegetable garden, and the severity of the infestation, hand removal may be overwhelming in your situation.
Preventing And Removing Witchgrass
Prevention is always better than killing the weeds. The best way to control the couch grass is by avoiding them in the yard in the first area.
Indeed, this problem does not always occur in a wide area of plants. It can also happen in potted plants.
However, it would be very easy to deal with witchgrass when it only happens inside a container or pot.
Well, you can just remove the weed completely with the roots immediately. Thus, it is very important to act quickly after the grass appears.
Witchgrasses have a quick movement throughout any type of soil. When it is loamy and sandy, they would be quicker than ever.
Therefore, keep checking your plants and lawn regularly. Remove them as best as possible. Do not forget the roots, because they would eventually regrow quickly.
To prevent the lawn from quackgrass, you have to give your lawn the best treatment and care. Because, when the stand of grass is thick and healthy, weeds will not pop up.
When you have a thicker lawn, the weeds will have less opportunity to grow. Besides, mowing the lawn with a higher setting can also be a good prevention method.
Further, it will eventually shade the ground and protect the soil from sunlight.
The soil that gets the sunlight would assist the weed seeds to grow. They actually wait for the best conditions to grow on the lawn. So, you just have to prevent that to happen.

Crowd Out The Quackgrass
When Quackgrass grows unchecked, it is an aggressive plant that spreads rapidly and takes up resources that your lawn grass needs to grow and thrive. To combat this sort of attack and get rid of Quack grass, youll need to be even more aggressive and overwhelm the weeds.
Planting new grass seed in areas where you see Quackgrass growing can often take care of your weed issue without requiring you to do any damage to the topsoil. This also works quite well as a way to kill crabgrass, too.
- Nitrogen fertilizer
To eliminate your Quackgrass problem, fill a seed spreader with a grass seed such as bluegrass, buckwheat, or ryegrass, and distribute new seed in areas that have signs of Quackgrass growth.
Spread more seed than is required, and give it lots of care to ensure that it has the optimum opportunity for growth. Water your new grass as needed, and feed with a nitrogen fertilizer.
The fertilizer suppresses the Quackgrass and encourages good grass growth. If you give the new grass lots of attention, it should overpower and starve out the Quackgrass. Mowing the new grass will also help remove the Quackgrass.
When To Rake Mulch Off Of Asparagus Plants
Rake mulch that has fallen from the garden in early spring before the first asparagus shoots touch the ground. Remove small weeds growing under the mulch and continue weeding as needed while the asparagus tips develop. When the stems are long enough to begin harvesting, replace the mulch to suppress weed growth.

Growth Characteristics Of Quackgrass
This grass mainly spreads by way of rhizomes. However, the means of propagation will depend on the prevailing soil conditions. Take an example of cropland where there is adequate light and a lot of nitrogen.
In this case, the grass would produce a lot of rhizomes and spread by this means. However, in grassland, the species would rely on seed production for propagation. Let us take a look at both methods.

How Does Quack Grass Spread So Quickly
Quackgrass has become notorious for its ability to suddenly invade lawns and wreak havoc on crop yields.
To successfully eliminate quackgrass from your lawn, you need to understand how this invasive weed spreads.
There are four main reasons why quackgrass spreads so quickly:
- It produces seeds by wind-pollination
- It spreads by prolific rhizome growth
- Each rhizome may form new plants
- It can easily outcompete other plants
Of course, this is all made possible by how quickly the rhizomes can grow and spread.
A single rhizome can grow by over an inch every day and can extend over ten feet from the mother plant!
Keep Your Lawn Healthy
The best defense against quackgrass is a healthy lawn, as the weed tends to appear in lawns that have patchy, loamy soil.
The following are ways you can help create a healthy, weed-free lawn:
- A soil test will help analyze your lawn’s soil for missing nutrients. After completing the test, you can then choose a fertilizer that meets your lawn’s nutritional needs and apply regularly.
- Water your lawn regularly, as needed. Water in the morning to allow the water time to dry and to prevent burning in the summer sun.
- Mow your lawn regularly, keeping the grass blades 1-2 inches long.
- Aerate your soil once or twice a year to help air and nutrients reach compacted soil.
- Fill in patchy areas of your lawn or overseed with grass seed.

Make A Homemade Quack Grass Killer Spray
Will vinegar kill grass, quackgrass, and other weeds? You bet. Acetic acid, or white vinegar, is one of the best natural weed killers you can use. When used in combination with salt and dish soap, you give that weed more than it can handle.
The dish soap helps the herbicide stick to the weed plant, while the salt and vinegar slowly dry it down to its root system. Take care while spraying this herbicide since it will kill any nearby plants, as well.
- Garden sprayer
For effectively killing quackgrass with vinegar, combine all ingredients and pour into a garden sprayer for large areas or a spray bottle for smaller areas of weeds. Set the sprayer to stream to prevent over-spraying onto nearby foliage. This remedy works best if you apply it during the sunniest time of the day with little to no breeze.
Spray the natural herbicide directly onto the quackgrass, making sure to saturate the weed without spraying nearby plants. Check the weedy area in a couple of days. If the plants are not dead, reapply the herbicide. Pull up the dead weeds and plant grass seed in the bare spots to encourage healthy lawn growth.
You can also try using baking soda. Killing crabgrass with baking soda, or any other type of weed, is easy with this household staple. Sprinkle baking soda on undesirable weeds and they will soon wither and die.
Does Vinegar Kill Quackgrass Weed
Vinegar can get rid of crabgrass. A strong solution of vinegar, when mixed with orange oil, can kill weeds for good. However, this process has to be done in the correct manner lest the weeds sprout forth again.
Most vinegar solutions are not effective in killing weeds because they are not appropriately prepared. While most blogs will give tutorials on how to make a vinegar weed killer, most of the content is laced with faulty information that does not yield any desirable result.
This is because most of these tutorials only show vinegar with an acidity of 5% which does not help significantly.
Household vinegar rarely kills weeds, though it may cause some of the weeds to shrivel and wilt a bit but not to die off completely. Noxious, hardcore weeds will need stronger agents for their complete eradication.
To ensure that you achieve better results with your vinegar solution, you need to get vinegar with an acidity of at least 10%.
You should, however, be careful when handling vinegar with more than 10 percent acidity because it is very potent and dangerously corrosive. It can burn your skin and cause very painful wounds.
To keep yourself safe, wear goggles, long sleeves, rubber gloves, and shoes when you are working with 10% to 20-% vinegar solutions. It is also important to apply vinegar mixed with orange oil.
While vinegar can solely destroy weeds without a problem, it is the orange oil component that greatly completes the entire process of weed control.

Threats: Why Is Quackgrass A Noxious Weed
Quackgrass has creeping rhizomes that grow at a fast rate. If left uncontrolled, the rhizomes can spread at a rate of ten feet a year, making this weed highly invasive.
Perfect example of why quackgrass is so difficult to control.

And that is not all. As it spreads, it weeds out native species in the land. Suppose it establishes in agricultural land, it can reduce the yield from the field as well as contaminate the crops. The farmer would suffer devastating losses accruing from this.
As the grass takes hold, it becomes more competitive. Where it is in high numbers, it can wipe out up to 80% of the crop yield, where potatoes are in play.
For corn yields, a farmer can expect losses amounting to 35% of the total yield. Depending on the crops ability to resist the invasion, the effects vary.
Take potatoes as an example. Studies show that rhizomes are not only capable of penetrating the hard soils that are characteristic of this crop- but they also grow into the tubers. How much damage would that cause?
And the spread of this grass is quite easy as it takes place during harvesting and cultivation. A fragment on machinery is enough to wreak havoc on crop fields. That is why this grass ranks as a noxious weed in tons of states.
