The Best Ways to Kill Crabgrass with Chemicals and Homemade Methods

Crabgrass is a common and pervasive weed that plagues lawns all over the country. Crabgrass is an actual type of grass that does not mix in well with typical types of lawn. Characterized by its pointy and rough grass blades, crabgrass spreads aggressively and grows in unsightly clumps throughout your yard.

Crabgrass can also germinate at an incredible rate sending out thousands of new plants each season. Getting rid of crabgrass can be a challenge, but it is worth it in the long run if you do a little research and planning. Here are a few tips on the best way to kill crabgrass and a few herbicide reviews to help you start your search. 

What Does Crabgrass Look Like?

If you aren’t familiar with this troublesome and invasive weed, crabgrass can often be confused with other weeds in your yard. It can sometimes have several different looks due to its ability to change along with different growing circumstances, so identifying it can be a problem. Typically, it has a spikey and rough blade that appears in clumps around your yard and is also sometimes called devil grass or quack grass.

So, what exactly is crabgrass? Here is an informational video to tell you more about crabgrass: 

How to Get Rid of Crabgrass without Chemical Weed Killers

If you are wondering how to get rid of crabgrass in the summer, you have a few options. You can always use an herbicide application that will get rid of those weeds in a couple of weeks, but you run the risk of damaging your yard if you aren’t careful. So, what kills crabgrass without killing grass? Here are a few ideas of how to remove crabgrass naturally:

Stop Crabgrass from Producing Seeds

If you can pull out as many plants as possible early in the year, you can get them out before they are able to set seed. Remember that mowing allows you more time to take out plants and, if you have large patches, an organic herbicide that uses citric acid and clove oil can help get rid of them.

Make Sure Not to Redistribute Seeds

Immediately bag any weeds you pull out and throw them away. If you want to compost them, leave them in a tied up bag in a sunny place between 4 to 6 weeks to allow the seeds to die in the heat. At this point, you can safely compost them.

Stop Germination

A healthy lawn that is thick and green will provide dense shade which will stop seeds from germinating. To help create a healthy lawn, make sure your mower is set at the top of the height range that is recommended for your lawn making it hard for crabgrass to outcompete your lawn for growth. Also water deeply and infrequently so that the soil’s surface can dry out and effectively kill any shallow-rooted crabgrass.

If you plan to plant lawn grass, do so in the fall so that frost will kill any crabgrass seedlings. And, if you have a thin lawn, spreading corn gluten in the springtime or before your rainy season will help to stop seed germination. Plus, as the corn gluten breaks down it will leave nitrogen that can then feed your established lawn.

Solarize Soil

Another suggestion is mowing your lawn as low as possible during one of the warmer and sunnier days of the year. Make sure to generously water your lawn and then cover it with a clear plastic sheet while sealing all the edges and making sure the plastic is not punctured.

You will want to leave it this way for four to six weeks allowing the plastic to heat up the ground killing any seeds underneath. Once you remove the plastic, you can reseed the area with the grass you prefer. Interested in learning more about crabgrass removal?

Killing Crabgrass with Baking Soda

Using common household items like baking soda is also an effective way to kill crabgrass. By just simply sprinkling the baking soda onto the crabgrass, you should have dead weeds in just a few days that you can then pull up and replace with grass seed. Interested in learning more about natural ways to get rid of crabgrass? Here’s a video on using baking soda in your yard: 

You can also use vinegar. Killing crabgrass with vinegar should be done sparingly so it doesn’t also kill your lawn. You can pour vinegar directly onto the weeds and then pull them up and reseed when the crabgrass dies a few days later. These natural methods are a cheap and natural alternative to herbicides.
