How To Remove Crabgrass

How to Get Rid of Crabgrass

Crabgrass also can be eliminated with a product labeled as a crabgrass killer or a non-selective weed killer, meaning it will kill any plant it gets on. If you prefer to avoid products with synthetic chemicals, look for ones that contain concentrated vinegar. Always make sure to follow label instructions when using weed killers. Even vinegar-based ones can burn skin, eyes, and lungs.

If you find crabgrass in your edible garden, weeding it out by hand is best. This plant has shallow roots, but using weeders or a trowel as a crabgrass removal tool will make the job easier. Don’t toss the uprooted weeds in your compost pile, though, because they could still reseed themselves. It’s better to toss in the trash.

If you pull up crabgrass from your lawn, prevent it from coming back by filling in the bare patch with grass seed. Cover it with a light layer of topsoil, and water well to help the seeds sprout. Wait to mow the new grass until it reaches at least 3 inches tall.

Uproot The Dead Crabgrass

For complete destruction of crabgrass, make sure to pull the weed by hand to clear the area for reseeding with turfgrass. You can also use a crabgrass weed puller such as the Fiskars Stand-Up Weeder to make your work a lot easier.

But why is this step important in the crabgrass control plan?

Crabgrass and other aggressive lawn weeds like to grow in areas that are thin or bare. So, youll need to pull up the dead crabgrass weeds in preparation for patching up the bare spots which is the next step in this procedure.

Leave Your Mower Blade Up

Another way to combat crabgrass from growing is by leaving your mower blade up throughout the summer instead of lowering it as the season gets underway. Yes, this means that youll probably have to cut your grass more often, but its also a great way to ward off crabgrass.

Crabgrass flourishes when it has direct sunlight. In arid climates, it can be difficult for grass and other plants to grow, which means the crabgrass receives direct sunlight. When you leave your mower blade up and leave your grass a little longer, the ground will be shielded from the sun by the taller grass. This will help to keep crabgrass from growing.

Vinegar is acidic and will burn the weeds in your lawn, killing them within a short time. When combined with baking soda, they make a great homemade crabgrass killer.

    Grow A Thick Mean Lawn To Starve Crabgrass

    Weeds cant grow in a lawn thats thick and dense. Heres how you can increase the volume of your lawn:

    • Water it once a week. This will send a signal to your plants to grow deeper, stronger root systems. Watering any more than this will weaken your lawns roots.
    • Mow your lawn higher than you usually do. 2-3 inches higher will crowd out crabgrass and stunt its growth.
    • Aerate and detach your lawn. You should do this at least once a year, especially if your turf has clay soil in it. This will improve oxygen circulation and promote a healthier, thicker lawn.

    Roundup is a non-selective chemical herbicide that contains glyphosate as its active ingredient. Here is how you can get rid of crabgrass using roundup:

    • Fill one gallon of water into a clean, chemical-resistant bucket. Add 2.25 ounces of Roundup herbicide to the water and carefully mix.
    • Keep mowing around the crabgrass for about two weeks to give it time to grow taller than your lawn before treating it with roundup.
    • Move the diluted Roundup herbicide into a spray bottle and apply the herbicide to the crabgrass foliage to the point of saturation.
    • As an alternative, you may soak a sponge in the roundup and cover the top of the crabgrass with it.
    • Wait ten days. Adjust the height of the lawn mower to its lowest setting, and then mow over the dead crabgrass.
    • To ensure that the roundup completely kills the weed, you might need to treat the crabgrass two to three times over the period of two weeks.

    Deeply Water Your Lawn

    Weeds thrive in stressed lawns. Most grass species benefit from deep watering. Make sure your lawn receives one inch of water per week, either from rain or watering. The water needs to soak the soil six to eight inches deep. Deep watering encourages your lawn to develop deeper roots, so it can grow thicker to help crowd out weeds.

    Use Baking Soda Vinegar Or Corn Gluten

    If you are wondering how to kill crabgrass all-natural way, applying home-made killers such as baking soda, vinegar, and corn gluten is a great idea. Its the stuff all of us generally have in our homes, so it will also save you a trip to the store and save you some money.

    Phytotoxin content of baking soda will do harm to any pant it comes in contact with. As with touring hot water, its best used in isolated areas and single patches of crabgrass.

    Simply spray some water over crabgrass or any other plant you need to be destroyed for that matter and sprinkle baking soda powder over it. In the course of a few days, you will see the results and then uproot the dead plants, rake the surface and plant new grass.

    Using vinegar is a great method of dealing with crabgrass since, while it has the same effect on plants as the

    Roundup, it does no damage to the soil, and after you apply it ground is ready for reseeding. The best way to use it is by combining it with salt and liquid dish soap.

    Vinegar and salt will dry the crabgrass out and soap will allow the plant to soak up the solution. Pour 1 gallon of vinegar, 1 cup of salt, and 1 tbsp of soap in a bowl or a bucket and mix it well. Spray the weed once a week, although youll generally notice the effect within a day or two.

    One of the best organic preventers of crabgrass growth is corn gluten. It obstructs the development of weed roots.

    Post-emergent herbicides eliminate existing weeds. When used on young, delicate weeds like crabgrass, they are especially successful at eliminating difficult-to-kill weeds. However, multiple treatments might be necessary to eradicate mature weeds, which can be detrimental to the nearby plants and grass.

    The best crabgrass killer for your lawn may depend on a number of variables. For example, do you prefer a product that exclusively targets crabgrass or one that kills other weeds as well? Also, will the herbicide be used during the weeds active growing season or in its dormancy?

    So make sure to do your research before choosing a crabgrass killer for your lawn. Nonetheless, here are my favorite crabgrass killers:

    Apply Natural Crabgrass Preventer In The Spring

    Pre-emergent, also known as a preventer, is a weed killer that can be used over your lawn before weeds have emerged. During the winter and early spring, crabgrass seeds can lay dormant underneath the soil waiting for the right conditions before growing.

    By applying pre-emergent to your lawn in the early Spring, the preventer will sink into the soil and kill off any crabgrass seeds that may be waiting around. As always, make sure you read the instructions on the pre-emergent to make sure it wont kill your grass or affect your animals or children if they walk in the yard.

    Reducing The Distribution Of Seeds

    Aggressive seed distribution allows crabgrass to spread through a large area, quickly dominating your lawn. One of the best ways to eliminate crabgrass without the help of chemicals is to prevent seed distribution.

    When you hand-pull grass patches from the ground, place them in a plastic bag and throw these bags immediately into the trashcan or landfill. This way, the seeds are contained with no way to disperse through your lawn.

    If you prefer to compost as much organic material as possible, you can tie up the bags and leave them out in the sun from 4 to 6 weeks. This method ensures that the seeds have been killed by the heat, leaving the remnants safe to add to your compost heap.

    How To Kill Crabgrass With Roundup

    If you plan on using a store-bought solution for killing weeds rather than a do-it-yourself remedy, Roundup is a great option. Roundup uses an active ingredient to kill weeds known as glyphosate, which kills most vegetation almost instantly. This weed killer is especially helpful when crabgrass has wholly overtaken your entire lawn.

    As a result, when you spray large areas at a time, it also kills most of your yard. Because crabgrass is still grass, using selective herbicides, like those designed for killing broadleaf weeds like a non toxic dandelion killer and sparing the lawns, doesnt work.

    Roundup kills weeds on contact down to the roots, including crabgrass and other weeds with which it contacts. Its the best way to retake control of your yard and act within a matter of minutes to control infestations.

    Water Your Lawn Once A Week

    How to kill crabgrass quickly without damaging your lawn
  • Encourage your existing grass to grow deep, healthy roots. The best way to discourage crabgrass from coming back is to make sure your lawn is thick and healthy. You can do this by giving it about 1 in of water per week all at once instead of a few short bursts. A once-a-week watering encourages deep root growth, while frequent short waterings encourage shallow roots.XResearch source
