If you have a lawn, you may have experienced the frustration of dealing with crabgrass. It’s an invasive weed that can quickly take over your grass, leaving you with an unsightly yard. But don’t worry, in this ultimate guide we’ll show you how to get rid of crabgrass for good.
What is Crabgrass?
Crabgrass is an annual weed that is a member of the grass family. It grows quickly and spreads easily, making it difficult to control once it takes hold in your lawn.
What Does Crabgrass Look Like?
Crabgrass has long, slender leaves that can be light green or yellow in color. It grows low to the ground and can quickly form a thick mat over your lawn. It also produces a lot of seeds that can easily spread to other areas of your yard.
Why is Crabgrass a Problem?
Crabgrass can be a problem for several reasons. First, it can take over your lawn and make it look unsightly. It can also choke out other plants in your yard, making it difficult for new growth to occur. Additionally, it can be difficult to get rid of once it has established itself in your lawn.
How Does Crabgrass Spread?
Crabgrass can spread in several ways. It produces a lot of seeds that can be easily transported by wind, animals, or lawn equipment. Additionally, crabgrass can spread through its roots, which can quickly take hold in your lawn and form new plants.

- Keep Your Lawn Healthy
- Apply Pre-Emergent Herbicides
- Treating Crabgrass
- Hand-Pulling Crabgrass

- Using a Lawn Mower
One of the best ways to prevent crabgrass is to keep your lawn healthy. This means fertilizing your lawn regularly, watering it properly, and mowing it at the right height.
Another way to prevent crabgrass is to apply pre-emergent herbicides before the weed has a chance to take hold. These herbicides work by preventing the weed from germinating in the first place.
If you only have a small amount of crabgrass in your lawn, you can try hand-pulling it. This can be effective, but it can also be time-consuming and difficult, especially if the weed has already established itself in your lawn.
If you have a large amount of crabgrass in your lawn, you may need to use herbicides to get rid of it. There are several types of herbicides available, including selective and non-selective options.
If you have a lot of crabgrass in your lawn, you may need to dethatch it. This involves removing the dead grass and other debris that can build up in your lawn, which can make it easier for new growth to occur.
If you have a lot of crabgrass in your lawn, you may need to use a lawn mower to remove it. This can be effective, but it can also be time-consuming and can damage your lawn if not done correctly.
Preventing Crabgrass
Preventing crabgrass from taking hold in your lawn is the best way to avoid the headache of dealing with it later on. Here are some tips on how to prevent crabgrass:
- Keep Your Lawn Healthy
- Apply Pre-Emergent Herbicides
- Mulch Your Garden Beds
- Don’t Overwater Your Lawn
- Avoid Overfertilizing
As mentioned earlier, keeping your lawn healthy is key to preventing crabgrass. This means fertilizing your lawn regularly, watering it properly, and mowing it at the right height.
Pre-emergent herbicides work by preventing the weed from germinating in the first place, so applying them before crabgrass has a chance to take hold is a great way to prevent it.
Crabgrass can also be a problem in garden beds, so mulching them can be a good way to prevent it from taking hold. The mulch will keep the soil moist and will help to prevent weed growth.
Overwatering your lawn can actually make it more susceptible to crabgrass, so it’s important to water it properly. Most lawns need about 1 inch of water per week.
Overfertilizing can also make your lawn more susceptible to crabgrass. Too much nitrogen can promote the growth of weed seeds, so it’s important to fertilize your lawn properly.
How to Apply Pre-Emergent Herbicides
Pre-emergent herbicides can be very effective at preventing crabgrass, but it’s important to apply them correctly. Here’s how:
- Timing is Key
- Follow the Instructions Carefully
- Water it In
- Reapply If Necessary
You’ll need to apply the herbicide at just the right time to get the best results. The ideal time to apply pre-emergent herbicides is when the soil temperature reaches 55-60 degrees Fahrenheit.
It’s important to follow the instructions on the herbicide carefully. Applying it incorrectly can reduce its effectiveness or even damage your lawn.
After applying the herbicide, you’ll need to water it in to activate it. Make sure to water the lawn thoroughly.
Most pre-emergent herbicides are effective for about 3-4 months, so you’ll need to reapply them if necessary to maintain control.
How to Keep Your Lawn Healthy
Keeping your lawn healthy is key to preventing crabgrass and other weeds from taking hold. Here are some tips on how to do that:
- Fertilize Regularly
- Water Properly
- Mow Correctly
- Aerate Your Lawn
- Use Quality Seed
Fertilizing your lawn regularly can help it grow strong and healthy, making it less susceptible to weed growth. Use a high-quality fertilizer and follow the instructions carefully.
Most lawns need about 1 inch of water per week. This water should be applied deeply and infrequently, rather than shallowly and frequently. This will encourage deep root growth, which will help to keep your lawn healthy.
Mowing your lawn correctly is important for its overall health. Make sure to mow at the correct height for your grass type and never remove more than 1/3 of the grass blade at once.
Aerating your lawn can help to loosen compacted soil, allowing water and nutrients to better penetrate the roots. This will help to keep your lawn healthy and less susceptible to weeds.
When planting new grass or overseeding an existing lawn, make sure to use high-quality seed. This will help to ensure that your lawn grows strong and healthy, making it less susceptible to weed growth.
How to Apply Herbicides
If you have a large amount of crabgrass in your lawn, you may need to use herbicides to get rid of it. Here’s how to apply herbicides:
- Choose the Right Herbicide
- Read the Label Carefully
- Apply According to Instructions

There are several types of herbicides available, so be sure to choose the right one for your particular situation. Some herbicides are selective, meaning they will only kill certain types of plants, while others are non-selective, meaning they will kill any plant they come in contact with.
Before applying any herbicide, be sure to read the label carefully. This will tell you how much to apply and how to apply it.
Follow the instructions on the label carefully when applying herbicides. Applying too much or too little can reduce its effectiveness or cause damage to your lawn.
After applying the herbicide, be sure to water it in thoroughly. This will help to activate it and ensure that it’s distributed evenly throughout your lawn.
