What Helps To Prevent Crabgrass

How to Get Rid of Crabgrass | Lawn Care and Maintenance | The Home Depot

It is a challenge to eradicate once smooth or hairy crabgrass sprouts, so focusing on prevention is critical. The best way to prevent crabgrass in your yard is to encourage healthy turn growth, so the desired grass crowds out the crabgrass. When your lawn is lush and thick, you will have fewer problems with weeds.

For a healthy lawn:

  • Overseed any thin or bare spots to fill patches in with grass.
  • Mow grass no lower than 3 in height. This taller height keeps the soil surface shaded from the sunlight and cooler in temperature, helping to see crabgrass seeds from germinating.
  • Water the lawn infrequently but deeply versus daily, light irrigation. Watering less frequently promotes deeper root growth, making the grass more drought-tolerant and hardy.

Along with fostering a healthy yard, you can apply a pre-emergent herbicide in the early spring to prevent crabgrass seedlings from establishing. Unfortunately, they dont always stop the seeds from germinating completely which is a misconception many homeowners have about this type of weed killer but instead, they inhibit shoot or root development so that seedlings cant become established plants.

Vinegar As Natural Crabgrass Killer

One of the most popular homemade weed killers for DIYers everywhere incorporates ingredients like vinegar, dish soap, and table salt. Both the vinegar and salt dry out the weed, while the soap breaks up the surface tension to allow the solution to soak into the plant. This recipe works best on a bright sunny day to speed up the drying out process.

  • 1 gallon of white vinegar
  • 1 cup of table salt
  • 1 tbsp of liquid dish soap

When preparing this DIY natural weed killer, mix the contents in a large bucket but keep a spray bottle nearby for more accessible application to specific weeds.

For the best way to get rid of crabgrass, liberally spray the weed, soaking all the blades of grass with the solution and allowing it to sink deeply into the roots. Use this method once a week as necessary, though you will generally notice results within two days of spraying. Pull up whats left of the weed and add some grass seed to the area to discourage further crabgrass growth.

Some Options To Eliminate Crabgrass Naturally

For homeowners wanting a more natural approach to eliminate crabgrass, there are a couple of non-chemical options. These methods are more environmentally sustainable but may take longer to get rid of the weeds. You can pull weeds by hand or apply corn gluten meal as a pre-emergent.

The first option is to pull crabgrass plants by hand. To make pulling weeds easier and more successful:

  • Pull crabgrass plants as soon as you see them. Smaller plants are easier to pull than larger ones.
  • Try to remove all of the roots if possible when pulling crabgrass. Grab each plant by the base and pull slowly and steadily upwards.
  • Weed just after it rains or water the lawn thoroughly.
  • Use a weeding tool such as a hoe or a weed popper.

Manual removal is the most labor-intensive option and may not be feasible for homeowners with physical limitations.

Corn gluten meal can also be used as an alternative to chemical pre-emergents, applied at a standard rate of 20 pounds per 1,000 square feet of lawn. It is an organic approach that prevents roots from establishing after the seeds germinate.

Using corn gluten meal for crabgrass control isnt as straightforward as chemical options. Timing is critical and impacts the effectiveness considerably. Corn gluten meal may also take more than one application to see the full benefits, and it may not get rid of the crabgrass entirely.

Controlling Crabgrass In The Spring

How to Get Rid of Crabgrass in Lawn

An effective way to eliminate crabgrass is to apply a pre-emergent herbicide before the crabgrass seed in your lawn can germinate. Timing when you apply the pre-emergent herbicide is very important. If done too early, while it is still too cold, crabgrass will most likely grow anyway. If applied too late, you may not see much benefit either. You should consider applying a pre-emergent herbicide when soil temperatures in your area approach 55 degrees F.

Many resources exist to help determine when this occurs, such as the growing degree day tracker from Michigan State University. This tracker can be helpful if you live in the Great Lakes region of the United States.

There is not currently any effective, selective treatment for actively controlling growing crabgrass. Because it is a type of grass, it is difficult to develop a treatment product that does not also affect desirable varieties.

However, there are several things that can be done to reduce the amount of crabgrass you get in the future.

As an Annual plant, crabgrass dies at the end of the year after frost, and a new plant grows from seed the next year. But before the crabgrass plant dies, each plant, depending on its size, can drop a minimum of 150-125,000 seeds which can lie dormant for years. So getting rid of crabgrass is all about preventing as much seed from developing, and growing on the lawn as possible.

When Is The Best Time To Mow A Crabgrass Lawn

You can reseed your lawn in the fall or early spring to give the grass enough time to germinate and grow before the crabgrass starts growing in the summer.

Alternative And Smarter Solution If You Already Have Crabgrass

Alternatively, a smarter and healthier solution to this is to simply wait and live with the crabgrass until the fall. There are a few reasons for this. First, if you have crabgrass on the majority of your lawn, when you kill it, you will have bare spots.

Not only will this make your lawn unappealing, but you also have to wait before you reseed the area . And, while youre waiting, the bare areas may attract other weeds, regardless of whether your reseed or dont. Youve inadvertently created a fertile area for crabgrass and other weeds. And, this will make it harder for your new grass to grow.

Second, if you can just wait until the fall, the crabgrass will naturally die on it own when it gets cooler. And, then there is no need for herbicide. Then, you can reseed the grass in the fall so it can start to grow. At that point of the year, grass will grow, but crabgrass wont.

Then in the spring, you will do pre-emergent herbicide to prevent the dormant seeds from generating.

We prefer this method because its more natural and generally more effective and efficient for your lawn.

How to Get Rid of Crabgrass (4 Easy Steps)

Spray post-emergence herbicide directly on crabgrass after it has sprouted. Pulling is equally effective, but if the roots are deeply embedded in your lawn, it may be tough to pull them out without pulling grass chunks, too. It’s not worth spraying a post-emergence product on crabgrass that has gone to seed. It takes about two weeks for the herbicide to work, which is about how long it takes the plant to finish its seeding process. If it has gone to seed, you’re better off waiting for next spring and applying a pre-emergence product then.

Post-emergence herbicides are most effective when the soil is moist and the plants are dry. Read the post-emergent crabgrass killer label for specific instructions. Typically you apply it with a hand pump sprayer. It’s best to apply it on a hot day when there’s low wind. If temperatures are too low, the product may be ineffective. Unless the crabgrass is young, you’ll probably have to reapply post-emergent crabgrass killer a few days later to kill the plant.

Winter is finally over, and your lawn is coming back to life. Unfortunately, your lawn grass may not be the only thing being reborn during early spring. There are several things you can do as part of spring lawn maintenance to prevent the emergence of crabgrass, dandelions, and other lawn weeds.

Springtime Lawn Care

The following is a general method of application, but read the manufacturers instructions for your particular herbicide.

Knowing when to apply the pre-emergent herbicide depends on your regional weather. Once the soil temperatures have risen above 60°F, apply the herbicide. Determine this by taking note of the shrubs and trees in your area. Once they begin blooming and budding, you can use the herbicide.

Of all the lawn care products out there, pre-emergent chemicals are probably the most misunderstood and misused.

Most people rush to the stores the second the weather starts to get nice in early spring, and they load up on a step 1 product that most fertilizer companies push.

The step 1 for most of these companies contains a crabgrass pre-emergent and a fertilizer all in one. On the label you can find a very broad time frame of when you are supposed to apply.

Theres nothing wrong with applying a step 1 product to your lawn. But for it to be fully effective you have to have an understanding of soil temps.

If youre looking for a simple crabgrass pre-emergent strategy then apply the step 1 twice. Your first application should be when your soil temps are approaching 55 degrees, and your second application should be about 5-6 weeks later as soil temps approach 70. This is a fine strategy if you want to keep things simple.

If youre looking for a more effective pre-emergent for crabgrass as well as other broadleaf weeds then consider using the following products at the correct soil temperature:
