Crabgrass is a common lawn weed that can be difficult to control. It is a fast-growing, low-growing grass that can quickly spread and take over a lawn. Crabgrass can crowd out desirable grasses and make a lawn look unsightly. In addition, crabgrass can harbor pests and diseases that can damage other plants in the lawn.

Importance of Controlling Crabgrass Naturally

Controlling crabgrass naturally is important for several reasons. First, natural methods are less harmful to the environment than chemical herbicides. Second, natural methods can be more effective in the long run than chemical herbicides. Third, natural methods are often less expensive than chemical herbicides.

Organic Herbicides

Organic herbicides, such as vinegar or clove oil, provide a natural and eco-friendly way to eliminate crabgrass. These substances contain active ingredients that target and kill the weed without harming beneficial plants or the environment.


Vinegar, a common household item, is a potent herbicide due to its high acetic acid content. To prepare a vinegar solution, mix equal parts white vinegar and water in a spray bottle. Apply the solution directly to crabgrass, avoiding contact with desirable plants.

The acetic acid will dehydrate the crabgrass, causing it to wilt and die. Repeat the application as needed until the crabgrass is eliminated.

Clove Oil

Clove oil, extracted from clove buds, contains eugenol, a natural herbicide. To use clove oil, mix 10-15 drops of the oil in 1 gallon of water. Apply the solution to crabgrass, ensuring thorough coverage. The eugenol will disrupt the crabgrass’s cellular processes, leading to its demise.

Cultural Practices

Implementing proper cultural practices can effectively prevent and control crabgrass in your lawn. These practices include mowing, watering, and fertilizing your lawn in an optimal manner. By following these guidelines, you can create an environment that is less conducive to crabgrass growth and promote a healthy, lush lawn.

Mowing, How do you get rid of crabgrass naturally

  • Mow your lawn regularly to a height of 2.5 to 3 inches. This prevents crabgrass from getting too much sunlight and helps thicken the lawn, making it more resistant to crabgrass invasion.
  • Avoid scalping your lawn by removing more than one-third of the grass blade at a time. Scalping weakens the lawn and makes it more susceptible to crabgrass.
  • Sharpen your mower blades regularly to ensure a clean cut. Dull blades tear the grass blades, making them more susceptible to disease and crabgrass invasion.


  • Water your lawn deeply and infrequently, allowing the water to penetrate the soil to a depth of 6 to 8 inches. This encourages deep root growth and makes the lawn more drought-tolerant, reducing crabgrass’s ability to establish itself.
  • Avoid overwatering, as this can create a moist environment that favors crabgrass growth.
  • Water your lawn in the morning so that the leaves have time to dry before nightfall. Wet leaves can promote fungal diseases that can weaken the lawn and make it more susceptible to crabgrass.


  • Fertilize your lawn regularly with a balanced fertilizer that is appropriate for your grass type and soil conditions. Fertilizing helps strengthen the lawn and make it more resistant to crabgrass invasion.
  • Avoid over-fertilizing, as this can promote excessive growth and create a dense canopy that blocks sunlight from reaching the soil surface, creating a favorable environment for crabgrass.
  • Use a slow-release fertilizer that will provide nutrients to the lawn over a period of time, rather than a quick-release fertilizer that can lead to a surge of growth followed by a decline.

4. Manual Removal: How Do You Get Rid Of Crabgrass Naturally

If you prefer a chemical-free approach, manual removal is a laborious but effective method to eliminate crabgrass. This involves physically extracting the crabgrass plants from your lawn.

Identifying crabgrass is crucial. It has a distinct bluish-green color, a low-growing habit, and forms dense clumps. The leaves are narrow and pointed, with a distinctive vein running down the center.

Hand Pulling

For small infestations, hand pulling is an efficient method. Use your fingers to gently grasp the base of the crabgrass plant and pull it out. Ensure you remove the entire root system to prevent regrowth.


For larger areas, tilling the soil can be effective. Use a hoe or cultivator to loosen the soil and disrupt the crabgrass roots. Be careful not to damage the desirable grass species in your lawn.

Natural Barriers

Natural barriers can be an effective way to suppress crabgrass growth without the use of chemicals. These barriers work by blocking sunlight from reaching the crabgrass seeds, which prevents them from germinating. Additionally, natural barriers can help to retain moisture in the soil, which can make it more difficult for crabgrass to establish itself.

There are two main types of natural barriers that can be used to control crabgrass: mulching and planting dense ground cover.


Mulching is a great way to suppress crabgrass growth. Mulch can be made from a variety of materials, including shredded leaves, bark, or compost. When mulch is applied to the soil, it creates a barrier that prevents sunlight from reaching the crabgrass seeds.

Additionally, mulch helps to retain moisture in the soil, which can make it more difficult for crabgrass to establish itself.

To use mulch to control crabgrass, simply apply a layer of mulch around your plants. The mulch should be about 2-3 inches thick. Be sure to keep the mulch away from the stems of your plants, as this can encourage rot.

Planting Dense Ground Cover

Planting dense ground cover is another effective way to control crabgrass growth. Ground cover plants are low-growing plants that spread quickly to form a dense mat. This mat can block sunlight from reaching the crabgrass seeds, which prevents them from germinating.

Additionally, ground cover plants can help to retain moisture in the soil, which can make it more difficult for crabgrass to establish itself.

There are many different types of ground cover plants that can be used to control crabgrass. Some popular choices include creeping Jenny, pachysandra, and vinca. When choosing a ground cover plant, be sure to select one that is well-suited to your climate and soil conditions.

Biological Control

How do you get rid of crabgrass naturally

The introduction of beneficial insects or microorganisms into the lawn can be a natural and effective way to control crabgrass. These organisms can prey on crabgrass seedlings, compete with them for resources, or release substances that inhibit their growth.

One common biological control agent for crabgrass is the parasitic wasp Diaparsis carinifer. This wasp lays its eggs in crabgrass stems, and the larvae feed on the plant’s tissues, eventually killing it. Other beneficial insects that can help control crabgrass include ladybugs, lacewings, and ground beetles.

Beneficial microorganisms that can be used to control crabgrass include certain species of bacteria and fungi. These organisms can produce antibiotics or other substances that inhibit the growth of crabgrass. One example is the bacterium Bacillus subtilis, which produces a substance called surfactin that has been shown to suppress crabgrass growth.

Attracting Beneficial Organisms

There are several things you can do to attract beneficial insects and microorganisms to your lawn and help control crabgrass:

  • Provide a diverse habitat.Beneficial insects and microorganisms need a variety of habitats to thrive. This means having a mix of different types of plants, including flowers, shrubs, and trees. It also means providing areas of bare soil or mulch where these organisms can nest and feed.
  • Avoid using pesticides.Pesticides can kill beneficial insects and microorganisms, so it’s important to avoid using them whenever possible. If you must use pesticides, choose products that are specifically targeted to the pests you’re trying to control.
  • Water your lawn deeply and regularly.Beneficial insects and microorganisms need moisture to survive. Water your lawn deeply and regularly, especially during hot, dry weather.
  • Add compost to your lawn.Compost provides nutrients for beneficial insects and microorganisms and helps to improve the soil’s structure. Add compost to your lawn in the spring and fall.
