How to Kill Crabgrass in Southern Lawns

If you live in the southern region of the United States, you know how difficult it can be to keep your lawn looking healthy and green.

One of the biggest challenges you may face is dealing with crabgrass. Crabgrass is an invasive weed that can quickly take over your lawn if left unchecked. Fortunately, there are several ways to kill crabgrass in southern lawns.

1. Pre-Emergent Herbicides

Pre-emergent herbicides are a type of weed killer that you apply to your lawn before the crabgrass has a chance to germinate. These herbicides work by creating a barrier in the soil that prevents the crabgrass seeds from sprouting. Some popular pre-emergent herbicides include Pendimethalin, Prodiamine, and Dithiopyr.

When using pre-emergent herbicides, it’s important to apply them at the right time. In the southern region, you should apply pre-emergent herbicides in early spring before the soil temperature reaches 55 degrees Fahrenheit.

Be sure to follow the instructions on the label carefully, as applying too much or too little can reduce the effectiveness of the herbicide.

2. Post-Emergent Herbicides

If you already have crabgrass in your lawn, you’ll need to use a post-emergent herbicide to kill it. Post-emergent herbicides work by targeting the crabgrass specifically, leaving your grass unharmed. Some popular post-emergent herbicides include Quinclorac, Fenoxaprop, and Mesotrione.

When using post-emergent herbicides, it’s important to apply them when the crabgrass is actively growing. In the southern region, this is typically in the late spring or early summer.

Be sure to follow the instructions on the label carefully, as applying too much or too little can reduce the effectiveness of the herbicide.

3. Manual Removal

If you only have a few patches of crabgrass in your lawn, you may be able to remove them manually. To do this, simply grab the crabgrass at the base and pull it out of the ground. Be sure to get as much of the root system as possible, as any remaining roots can allow the crabgrass to regrow.

Manual removal can be time-consuming, but it’s a good option if you don’t want to use herbicides in your lawn. Just be sure to dispose of the crabgrass properly, as any seeds left behind can still germinate and spread.

4. Proper Lawn Care

Finally, one of the best ways to prevent crabgrass from taking over your lawn is to practice proper lawn care. This includes regular mowing, watering, and fertilizing. When you keep your lawn healthy and thick, it’s more difficult for crabgrass to take hold.

Additionally, you can overseed your lawn with a warm-season grass like Bermuda or Zoysia. These grasses are more resistant to crabgrass and can help keep it under control.

Prevention of Crabgrass

Nobody likes crabgrass. It’s an invasive weed that can take over your lawn if you’re not careful. Luckily, there are steps you can take to prevent it from appearing in the first place. Here are some tips to help you keep your lawn crabgrass-free.

Keep Your Lawn Thick and Healthy

One of the best ways to prevent crabgrass is to keep your lawn thick and healthy. A thick lawn will choke out any weeds that try to grow in it, including crabgrass.

keep your lawn thick, make sure to fertilize it regularly and water it deeply and infrequently. You should also mow your lawn regularly and at the right height. For most southern lawns, the ideal mowing height is between 2.5 and 3 inches.

Use a Pre-Emergent Herbicide

Another effective way to prevent crabgrass is to use a pre-emergent herbicide. This type of herbicide is applied before the crabgrass seeds germinate, and it prevents them from growing. Some of the best pre-emergent herbicides for southern lawns include:

Prodiamine
Dithiopyr
Pendimethalin

Make sure to apply the herbicide at the right time. In most southern states, the best time to apply a pre-emergent herbicide is in early spring, before the soil temperature reaches 55 degrees Fahrenheit.

Fix Bare Spots

Bare spots in your lawn are an invitation for weeds to grow, including crabgrass. To prevent this, make sure to fix any bare spots as soon as possible.

You can do this by overseeding the area with grass seed or by laying down sod. Make sure to keep the area well-watered until the grass is established.

Don’t Overwater Your Lawn

Overwatering your lawn can actually make it more susceptible to crabgrass. When you overwater your lawn, the soil stays moist for longer periods of time, which can encourage crabgrass to grow.

Instead, water your lawn deeply and infrequently. Most southern lawns need about an inch of water per week, either from rainfall or irrigation.

Best Time to Kill Crabgrass

When it comes to killing crabgrass, timing is everything. The best time to kill crabgrass is in the spring before it has a chance to take root and spread. Crabgrass is an annual weed, which means that it dies off at the end of the growing season and reseeds itself in the spring. By targeting crabgrass early in the season, you can prevent it from spreading and taking over your lawn.

The ideal time to apply pre-emergent herbicides is when the soil temperature reaches around 55 to 60 degrees Fahrenheit. This typically occurs when the Forsythia or Redbud trees start blooming in your area. Applying pre-emergent herbicides too early or too late can reduce their effectiveness.

It is important to note that pre-emergent herbicides only work on crabgrass seeds that have not yet germinated. Once the crabgrass has sprouted, it is much more difficult to control. If you miss the window for pre-emergent herbicides, you can still use post-emergent herbicides to kill the crabgrass. However, these herbicides can also harm your lawn, so use them sparingly and carefully.

In addition to herbicides, you can also use organic methods to control crabgrass. Hand pulling is an effective method for small patches of crabgrass. When pulling crabgrass, make sure to remove the entire root system to prevent regrowth. You can also use a hoe or cultivator to remove crabgrass from larger areas.

Tools Needed

When it comes to killing crabgrass in your southern lawn, there are a few tools that you’ll need to have on hand. In this section, we’ll go over the necessary tools for both chemical and non-chemical methods.

Chemical Herbicides

If you’re planning on using chemical herbicides to kill your crabgrass, then you’ll need to have the following tools:

Sprayer: You’ll need a sprayer to apply the herbicide to your lawn. Make sure that you choose a sprayer that is appropriate for the size of your lawn.
Post-emergent herbicide: This type of herbicide is designed to kill crabgrass after it has already emerged from the soil. Look for a product that contains either quinclorac or fenoxaprop-p-ethyl, as these are both effective at killing crabgrass.
Pre-emergent herbicide: This type of herbicide is designed to prevent crabgrass from germinating in the first place. Look for a product that contains either dithiopyr or prodiamine, as these are both effective at preventing crabgrass from growing.

Non-Chemical Methods

If you’re planning on using non-chemical methods to kill your crabgrass, then you’ll need to have the following tools:

Weeding tool: You’ll need a weeding tool to remove the crabgrass from your lawn. Look for a tool that has a pointed end, as this will make it easier to remove the crabgrass roots.
Gardening gloves: It’s important to wear gardening gloves when removing crabgrass, as it can be difficult to remove and may have sharp edges.
Mulch: Mulch can be used to prevent crabgrass from growing in the first place. Apply a layer of mulch around your plants to prevent crabgrass from germinating.

By having the right tools on hand, you’ll be able to effectively kill crabgrass in your southern lawn. Whether you choose to use chemical or non-chemical methods, make sure that you follow the instructions carefully to ensure that you get the best results possible.
