What is Water Grass
Those unfamiliar with gardening may think that water grass is a grass that grows in water. This is not the case however. Water grass actually is a fairly common lawn invader. It is a member of the sedge family, and grows in improperly maintained areas
Water grass is an aggressive invader of lawns and garden beds, making it difficult to control. It thrives in wet soils that are not regularly mowed or maintained. It also grows very quickly, spreading its seeds across large areas with ease. What makes water grass so hard to control is that it’s a perennial plant – meaning it will return year after year unless properly eradicated from the area.
It quickly can choke out other plants, as it has an extensive root system that will overtake weaker competitors. This makes water grass a difficult problem to manage, especially if left unchecked for too long. [1], [2], [3], [4]
Types of Water Grass
Before attempting to remove water grass, you should properly identify the species that is present. The following are some of the more common types of water grass.
Crabgrass
Crabgrass is a type of grassy weed that invades lawns, often faster than desired. It is an annual plant that grows from seed each year and spreads quickly as it takes root in the soil. The individual blades are thick and coarse, forming a dense mat that crowds out desirable grasses and can be difficult to control without proper intervention. These weeds thrive in sunny locations with moist soils and may even survive drought conditions due to their extensive roots. Understanding how these weeds spread can help homeowners take steps to prevent or eliminate them from their lawns altogether.
You can identify crabgrass by its distinctive blades, which grow in a star-like pattern with a slightly curved tip. They are typically more muted in color than surrounding grasses and may have purplish or reddish hue at their base. The weeds also tend to be coarser and more fibrous in texture. Additionally, crabgrass has a deadhead that is visible when the plant matures, which is a telltale sign of its presence.
Those seed heads are the source of crabgrass’s spread, as each one can produce thousands of seeds! Those seeds can travel through wind or water, leading to uncontrolled growth in other areas. This makes prevention especially important when it comes to this type of weed.
Quack-grass
Quack-grass is another common type of water grass found in many ponds and lakes. It is a warm-season annual that has long, slender leaves which are flat at the base with a sharp point at the top. Just like crabgrass, quack grass has seed heads that are spike-like, but they are thinner and longer. Quack-grass has a spreading habit and can quickly spread to fill an entire pond or lake. Because of its dense growth and quick spread, it is important to get rid of quack-grass as soon as possible if it begins to appear in your pond or lake.
Nimblewill
Nimblewill is a common grass that grows quickly and aggressively on lawns, especially in poorly drained areas. It spreads rapidly and can overtake a lawn in short order if left unchecked. Nimblewill is difficult to kill, because it has extremely deep roots which many herbicides don’t reach.
Nimblewill is pretty easy to identify. It’s a bright green grass that grows in tufts, and it has thin stems and thin flat blades with four veins. The leaves are primarily at the tips of the stems, while they’re absent from the lower part of the plant. Leaves are rolled in a bud when the grass is young. Nimblewill almost always grows in a dense clump and is highly resistant to drought. [2], [3], [4]
How to Kill Water Grass
Once you’ve identified which type of water grass is present in your pond or other water source, you can begin to tackle it using a variety of methods we are going to discuss in this section. You must be quick and take action in order to effectively rid your lawn of any water grass.
The most common methods of killing water grass are: chemical treatments, manual removal, and natural predators. Each of these methods is discussed below in detail.
Using a herbicide
A herbicide is a chemical treatment designed to kill water grass and other weeds. Herbicides can be bought from many stores and online retailers, such as Amazon.
The use of chemicals can be an effective way to get rid of water grass, as long as you choose the right herbicide for the job. Different types of weed killers work better on different types of weeds, so make sure to select a product that specifically targets the type(s) you’re dealing with.
Quinclorac is one of the most commonly used herbicides for killing water grass. Quinclorac is a post-emergent herbicide that is used to target grassy weeds such as watergrass, crabgrass, and foxtail. It is also effective against many broadleaf weeds, such as spurge and oxalis. Quinclorac works by disrupting cell membranes of the targeted plants, ultimately resulting in wilting and death.
Spot treating is the most effective way to use a herbicide. To do this, mix the herbicide with water in a spray bottle and apply it directly to affected areas using a tightly focused stream of liquid. This will ensure that only the weeds you’re targeting are affected and not your other plants.
When applying the herbicide, you should always read the label carefully and follow all instructions closely. Make sure that the applied product is specifically designed for killing the type of water grass present in your water source.
Using vinegar
An effective DIY method of killing water grass is to use vinegar. Vinegar has acetic acid, which disrupts the plant’s cell walls and causes it to wilt and die.
White vinegar will do fine for this method, but you can also use apple cider or other organic vinegars. To apply it, simply pour the vinegar into a spray bottle and apply it to areas of grass where there is an infestation.
The best time to apply this method is on sunny days when the soil is dry, as this will give the vinegar time to be absorbed by the soil and take effect. Be sure to wear protective clothing and gloves when applying this solution, as it can cause skin irritation if handled directly.
You may also look for a commercial vinegar-based glass cleaner that is designed specifically for killing grasses. These products are much stronger than regular household vinegar and should be used with caution.
Vinegar is not selective, so be careful when applying it around other plants that you want to keep alive! As with herbicides, it’s best to spot and treat only the weeds you are targeting.
Pulling the plants by yourself
Sometimes water grass can be pulled out by simply taking a shovel or rake and pulling it from the ground. This method works best for younger plants and smaller clumps of grass, as it requires some physical strength. Make sure to remove the entire plant and its roots to prevent regrowth. Leaving even a smallest piece of root behind can cause the grass to grow back.
After you get rid of plants, dry them under direct sunlight before throwing them away. This will prevent the spread of seeds and help reduce future growth of water grass in that area.
Contact the professional
Unfortunately, there are times when nothing seems to help and you find yourself in a situation where the water grass is not responding to any of the methods you’ve tried. In this case, it is best to consult with a professional lawn specialist or company who can assess the area and determine what the best course of action would be.
The lawn specialist will be familiar with several different kinds of treatments that they can use to get rid of the problem, such as chemical treatments, manual removal, and even introducing natural predators into your pond. They may also recommend other strategies such as draining some of the water from your pond or implementing an aeration system.
It’s important to note that hiring a professional service may cost more upfront but could potentially save you time, money and energy in the long run. Sometimes, it’s best to leave the job in the hands of an experienced professional who can use their expertise to ensure that you get rid of any water grass present in your pond or other water source.

FAQ
How to kill crab grass? (detailed answer)
Crabgrass is a type of water weed that can be difficult to eradicate. However it is certainly possible to eradicate crabgrass and keep your water clear.
The easiest option by far is using a herbicide that is designed to target and kill crab grass. You should make sure you choose one that is specific for water weed, as some herbicides can have an adverse effect on aquatic wildlife in the surrounding area.
Once you’ve chosen an appropriate herbicide, you need to get it into the water so it can reach the roots of the crab grass and destroy them from within. The best way to do this is with a sprayer, such as a backpack or handheld sprayer, which will allow you to evenly distribute the liquid across your body of water with minimal effort. Make sure to follow all safety instructions when using any kind of chemical product around bodies of water.
What is the best way to permanently kill water grass?
The best way to permanently kill water grass is to use a chemical spot treatment. Spot treatments typically involve applying a herbicide directly to the affected area of your lawn. This will kill the grass without affecting any other vegetation or soil around it. Additionally, spot treatments are more effective than broadcast applications because they allow for better control over exactly where the chemical is applied.
When using a spot treatment, be sure to read and follow all instructions on the product label before use. This will ensure that you use the herbicide safely and effectively, as well as reduce potential harm to yourself, pets, and other nearby plants. Additionally, when using a chemical spot treatment always wear protective clothing such as long sleeves and pants and rubber gloves for personal safety.
After you apply the spot treatment wait 2-3 weeks then inspect the area to make sure the grass is completely dead. Finally, if necessary you can use a rake or shovel to remove any remaining dead grass. With proper application of a chemical spot treatment and some patience, you should be able to permanently kill water grass in your lawn.
Will vinegar kill water grass?
Yes, vinegar can kill water grass. It is a non-toxic and natural method that works best in small patches of aquatic weed growth. To use it, take concentrated white vinegar, which is at least five percent acetic acid, and spray it directly onto the water grass bed. The acetic acid will kill the weed by disrupting its cellular structure and changing its pH balance. The vinegar also works to prevent water weeds from producing oxygen through photosynthesis, as well as nutrients that help keep them alive, thus killing them off quickly. It is important to note that using too much vinegar can be damaging to other plants in the area, so use caution when applying it.
What kills water grass the fastest?
One of the fastest ways to kill water grass is with a non-selective herbicide. These herbicides work by coming in contact with the plant and killing it almost instantly. They are fast-acting, meaning that you can see results within hours or days rather than weeks or months. Non-selective herbicides will kill any living vegetation they come into contact with—including both broadleaf plants and grasses—so be sure to apply them carefully so as not to damage any desirable plants in your yard or garden!
In addition to using a non-selective herbicide, there are other methods of killing grass that may take longer but may be more suitable for certain situations. For example, if you have areas of water grass that you want to kill, you can use a concentrated vinegar solution. Vinegar works by burning the leaves of the grass and is safe to use around other plants in your garden or yard, though it may take a few days before you see results.
What is water grass?
Water grass is a type of lawn grass that is most often found in areas that are poorly maintained and have standing water. It tends to thrive in damp and humid climates, growing in thick mats that can quickly outcompete other vegetation for resources. Water grass is a resilient weed that can be hard to get rid of once it takes hold of an area.
Therefore, it is important to take a proactive approach when it comes to preventing and controlling water grass. Regular mowing, fertilizing, and aeration can help maintain a healthy lawn that is less likely to succumb to water grass.
