9 Best Crabgrass Killers – In-depth Guide, FAQs and More

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 of 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 prepared 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.

Best Crabgrass Killers - Top 9 Reviews

Crabgrass Killers are divided chiefly into three types, pre-emergent, post-emergent, and two in one preventer+killer herbicides. You apply the pre-emergent herbicides after clearing crabgrass to deter the seeds from thriving.

It’s almost impossible to mow the crabgrass without the seeds spilling all over the place; that is why the pre-emergent herbicides are used for this objective. The post-emergent herbicides, on the other hand, can be used on the soil when the seeds might have germinated to control their growth.

The two-in-one herbicide performs the role of curbing the roots from growing and killing off the developed seeds.

Nevertheless, as good as these herbicides might be, some of them are dangerous for your lawn type. You should take a sample of your lawn to the local nursery to discern what kind of lawn you have. It is the goal of anyone who owns a garden or yard to keep it beautiful and perfect.

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.

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?

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?

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?

Yes, Baking soda extracts water from the stems and roots, resulting in a lack of water which then destroys the cells and tissues, and causes weeds like crabgrass to die off quickly. 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.

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.

How do you get rid of crabgrass in summer?

You can get rid of crabgrass in summer either by using chemicals or not.

To use chemicals, use post-emergence herbicides. When crabgrass is covering your garden, the best solution is to use chemical treatments. Select the correct type of herbicide for the garden and carefully read and follow instructions. This article has earlier discussed different types of herbicides to choose from. Scroll up to see them.

How to get rid of crabgrass naturally?

  2. Water the lawn at least once a week or twice weekly.
  3. When you mow, do not go less than 3 inches. Crabgrass leaves when the grass is cool and shady. So, cut high to provide shade for the soil.
  4. Lastly, when spring arrives, use a pre-emergent herbicide. It prevents crabgrass from growing.

If you follow these steps, you’ll be able to get rid of crabgrass plants in summer.

What time of the year is best to kill crabgrass?
