Best crabgrass killers in 2021

Crabgrass is no friend of your lawn. It absorbs the essential nutrients and moisture that a garden requires giving no room for other grass to grow. You’ll see crabgrass persisting and growing even in bad conditions. Crabgrass is exceptionally persistent. It provides a kind residence for pests. When crabgrass starts to grow, it seeks more space to spread. During hot weather, crabgrass almost presides over a lawn because it becomes hard, for that is the weather it loves. Crabgrass is an annual weed and produces about 80 thousand seeds. These seeds will be on the law and will be preparing for germination during spring. A little crabgrass today can result in myriads in just a year. When other grasses die during the hot and dry season, crabgrass doesn’t. Since that’s what it loves, so it ends up occupying a large amount of space on your lawn.

Since crabgrass is an annual weed, some people believe it won’t pose a problem, but do not underestimate it. Crabgrass produces a large number of seeds that quickly spreads out and overshadow other grasses. And annually, it continues to dominate the lawn making it impossible to get rid of it. There are indeed different homemade solutions said to be used to get rid of crabgrass. These solutions include using vinegar, salt, a dishwasher, or a knife. While these homemade solutions seem easy, they are not entirely adequate. Using some of these things can even harm the soil and other grass.

As you know, Applying salt to the ground will undoubtedly lead to an increase the land salinity. And when the soil has high salt concentrations, there’ll be a slow water movement from the earth to the root. Soil absorbs water from the base when the salt concentrations in the ground are high compared to that of the root cells, which causes plants to wilt and eventually die. How about using a knife? Using a knife to get rid of crabgrass takes time and requires accuracy. Since the roots are firmly deep in the soil, you may end up spreading the seeds on the ground, therefore, causing this annual weed to start preparing for the subsequent germination. What about the danger of using a knife? Let’s not get started about the risk of getting injured while using a sharp knife to remove crabgrass. But does this all mean there’s no way to get rid of crabgrass without any setback? No is the answer. There’s a solution that would help rid off crabgrass entirely without affecting the soil, harming yourself, or destroying your desired grass; that is the application of crabgrass killers!

Why is crabgrass bad for you?

Since crabgrass is an annual weed, some people believe it shouldn’t be a problem, but the case is quite the opposite. Crabgrass produces many seeds that are known to spread out speedily and possibly take over a lawn. And annually, it continues to dominate the yard making it impossible to get rid of it. Just like weeds do, crabgrass absorbs the essential nutrients that a lawn needs. It often prevents other grass from growing. While it is known to be persistent, it also keeps pests. When crabgrass starts to grow, it seeks more space as it spread. During hot weather, crabgrass almost presides over a lawn because it becomes hard to get rid of it. When other grasses die during the hot and dry season, crabgrass doesn’t. Since that’s what it loves, so it ends up occupying a large amount of space on your lawn. Crabgrass is annual and produces about 80 thousand seeds. These seeds remain on the lawn as they prepare for germination during spring. A little crabgrass today can result in myriads in just a year. While you strive to maintain a beautiful lawn, it only takes crabgrass to ruin your efforts. This domineering grass doesn’t benefit other grass. Instead, it deprives them. For these reasons, lawn owners work hard to prevent the growth of crabgrass. And even when it grows, they get rid of it using herbicides or home remedies.

What is the best way to get rid of crabgrass?

Knowing what crabgrass can do to your lawn will move you to take careful measures to ensure that you prevent its growth. However, what do you do if crabgrass already appeared? First, know some things about crabgrass. Crabgrass is annual and loves warm or hot weather. Crabgrass indeed dies the same year it thrived. However, while it lives, it produces up to 150,000 seeds. If the seeds that each crabgrass generates are that many, about seven more will turn a lawn into a crabgrass field. These seeds will then germinate again and result in numerous crabgrass.

As crabgrass seeds lay on the lawn preparing to germinate, it is a good time to prevent them from growing. Using crabgrass killer is one effective way. They are also called “herbicides.” The herbicide that you need to use before the seeds germinate is called “pre-emergent.” This type of crabgrass killer impedes the growth and development of the root. Remember that it is essential you apply the herbicide at the right time. Proper timing is a determinant of success.

What if the crabgrass germinated already? Do you still make use of pre-emergent herbicides? The answer is “NO.” Instead, it would help if you had a post-emergent herbicide. This type of herbicide goes after the plants and not the seed. It kills growing crabgrass plants so that it does not yield more seeds.

Before choosing a crabgrass killer, be sure if it is a selective or non-selective type. What is the difference? As the name implies, selective herbicide goes after some particular kind of weeds and plants. While the latter type goes after all plants, these involve your desired plants. Below are some of the effective herbicides that can get rid of crabgrass:

Select Source Quinclorac Herbicide

Select Source Quinclorac is a Post-emergent crabgrass killer. It is practical and kills different types of weeds.

Bayer Acclaim-Extra selective Grass Herbicide

This is a selective herbicide. It can be used to kill already developed crabgrass. It also kills other weeds in the garden. It is one of the best.

BASF Drive Crabgrass Herbicide

This is another effective crabgrass killer. It is, in fact, the best crabgrass killer. With this herbicide, you can kill crabgrass and restore your beautiful lawn.

Should I pull out crabgrass?

Crabgrass is an annual weed. Some people believe it won’t pose a problem, but do not underestimate it. Crabgrass produces a large number of seeds that quickly spreads out and take precedence over other grasses. And annually, it continues to dominate the lawn making it impossible to die. However, it is not impossible to kill crabgrass. There are indeed different homemade solutions said to be used to get rid of crabgrass. These solutions include using vinegar, salt, a dishwasher, or hands. Just a crabgrass yields 150,000 seeds which are sufficient to put your lawn in peril. So before you allow that, get rid of crabgrass. The question is, “should you pull out crabgrass?” Well, as much as this method is efficient, it can turn out to be dangerous. When crabgrass plants seem hard and require you to use some muscles, it could turn out bad. When you try to pull out hard crabgrass, you put your lawn at risk of getting sprayed by the seeds. So even if you want to pull out crabgrass, go after the young ones since they often have few holes for seeds. While on the other hand, the matured ones usually have seed heads that hold up to thousands of seeds. Watering the young ones before pulling them out also makes it easy to do.

How do you control crabgrass naturally?

It takes time and effort to make your garden beautiful. It even takes more time and effort to maintain it. So while you’re satisfied with the condition of your garden, you keep working hard to prevent anything from destroying it. But what do you do when crabgrass suddenly starts to grow on your lawn? When crabgrass plants begin to grow in your yard, you know it time to fight against them. It would be best if you killed them, or they’ll take over your lawn. Crabgrass doesn’t go quickly. But with the proper methods, you can kill crabgrass.

Apart from using herbicides to kill crabgrass, there are numerous natural ways to control crabgrass. Sometimes when we use herbicides to kill crabgrass either before growing or after it has germinated, the occurrence of crabgrass might resurge again. The herbicide will kill the crabgrass plants, but it’s not conclusive that you’ll never see crabgrass plants again in later times. Below are natural ways to control crabgrass:

Pulling out crabgrass is an effective method when you carefully do it. After pulling out crabgrass, remember to spread seeds on bare spots immediately.

Whenever you see bare spots, cover them up by spreading your preferred grass seeds.

When you mow your lawn, mow high. Never cut too low. Light is essential for crabgrass to grow. So, when you mow high, you provide a kind of shade for the soil, which keeps the ground cool. In such a situation, crabgrass plants leave.

Vinegar is another natural ingredient for killing crabgrass. Yes, you read that right. Vinegar doesn’t just serve as food flavor but also as a weed killer. Vinegar has proven to be effective in getting rid of crabgrass. It is accessible and inexpensive. Spraying crabgrass plants with vinegar will kill them. However, you’ll have to respray if the rain falls after the initial spraying. Small weeds are easily susceptible to death. While old weeds will require you to spray them thoroughly before dying. The acetic acid in vinegar makes it a plant killer. But, you need to be careful because vinegar is a non-selective killer. Therefore, any plant you spray will die.

Boil crabgrass

Boil, you say? Yes! Pour hot water on crabgrass to kill it. When doing this, be careful not to burn yourself. Also, the hot water might affect the plants around the crabgrass. Be sure to reseed.

Table salt is another home remedy. You can either pour salt on the crabgrass plants or make a mixture. Apply only to the crabgrass so that you don’t kill other plants.

Does baking soda kill crabgrass?

No doubt, crabgrass can damage your lawn. You wouldn’t want the garden you’ve worked so hard to maintain to go wrong. Therefore, when you notice the growth of crabgrass plants, it’s a significant step to prevent further development so that other plants do not suffer and you get to maintain that beautiful lawn of yours. Herbicides are popular for killing crabgrass. At the same time, you can choose not to use herbicides though it is more effective and instead go for natural remedies like baking soda. Baking soda extracts water from the stems and roots, resulting in a lack of water which then destroys the cells and tissues, which causes weeds like crabgrass to die off quickly. So, the answer to the question is “yes.” Once baking soda destroys the foliage of crabgrass, it makes it hard for it to grow again because crabgrass has no underground rhizomes that grow once baking soda eliminates the leafage.

Here’s how to use baking soda on crabgrass:

Wet the area of the crabgrass with a moderate amount of water to make baking soda attach to the foliage and stems easily.

Baking soda is a non-selective weed killer. Therefore, it will be toxic to other grass plants. So, baking soda should not come in contact with other grasses. You do well by covering other plants that are close to the crabgrass to prevent them from dying.

You should then spread the baking soda on the wet crabgrass area. Ensure that you cover the foliage sufficiently. It’s okay to repeat this process after some days if you still notice some crabgrass in your garden.

After this process, the foliage will start to turn white. It is one of the signs that the application is working. You will also notice discoloration (the leaves get black) as well stunted growth. Give the crabgrass enough time to die before yanking it out.

Then, preferably, use your hand or a weed puller to pull out the dead crabgrass. When you do this, you prevent the weed from regrowing on the bare areas. Afterward, fill up the spaces with new plants.

Reseeding is essential when you need to control crabgrass. So, once you uproot, fill the areas with topsoil and spread your new preferred seeds, and apply fertilizer. Do not forget the watering part.
