Any time that you might feel like you’re making progress, they seem to pop up again.

We understand the frustrations around how to get rid of lawn weeds. Our climate does make weed growth prevalent. But the good news is that you can manage North Texas lawn weeds with the right approaches and control products.

In this guide, we’re going to answer some of your most common questions around how to get rid of weeds in grass—as well as how to prevent many of them in the first place! Hopefully, with these handy tips you’ll be able to start getting your lawn on track to producing amazing results without pesky weeds standing in your way.

What Are The Most Common Weeds in Texas?

First and foremost, before you can figure out how to get rid of weeds in grass, you need to know what you're dealing with!

There are so many different types of weeds in Texas, so we won’t address them all.

Instead, we’ll just tell you a little bit about Texas grass weeds identification, by sharing some of the most common species that we see.

You can read an entire article that we wrote about these notorious weeds if you want to know more about each one, but here’s a quick overview.

  • Crabgrass: This grassy weed comes in two forms in North Texas: Smooth Crabgrass and Hairy Crabgrass. Both are major nuisances and reproduce and spread quickly.
  • Dallisgrass: Another one of the grassy weeds, Dallisgrass tends to grow in clumps and stick out in lawns due to its bunch-like appearance.
  • Nutsedge: This perennial weed has a triangular stem and foliage that sprouts in groups of three. It grows in warmer months and goes dormant in cooler months.
  • Poa Annua: Also known as annual bluegrass, Poa Annua grows upright and has creeping stolons. It is incredibly difficult to control.
  • Henbit: This cool-season annual broadleaf weed crops up in early fall and grows through winter into spring. It has square, slender stems that branch out from the base, and its leaves are circular and hairy. Henbit has shallow roots, and it spreads aggressively during the off-season in north Texas, which is why year-round lawn care is critical for maintaining healthy turf.
  • Spurge: Spurge leaves are oval and oblong with serrated edges and have some purple in the center. It is a broadleaf weed that germinates in late spring and grows during the summer.
  • Dandelion: Known for its bright yellow flower, the dandelion has a deep, thick taproot that can grow 6 to 12 inches deep and a long, single stalk. It grows from April through June and spreads rapidly during that time.
  • Bittercress: Known for its tiny white flowers, bittercress is a winter annual weed that emerges in early spring. It is especially prevalent after rainy periods because it thrives in wet ground. Bittercress has a long tap root.

The important thing to remember about these different types of weeds in Texas is that they’ll have different control methods to keep them in check. The best lawn treatment for weeds will definitely depend upon what you’re dealing with.

How to Prevent Weeds From Growing in Your Lawn

Instead of diving into how to kill weeds in grass, let’s talk about preventing weeds in the first place. That's always the ideal situation.

To prevent weeds from growing in your lawn, you should be utilizing pre-emergent applications which work by creating a barrier that doesn’t allow weeds to germinate. Specialized pre-emergent products, like those intended for crabgrass, work quite well to prevent a large majority of weeds from growing.

But pre-emergents won’t prevent everything.

There can be breaks in that barrier made by mowing and trimming, digging, dryness, cracking, or even excessive rain. That’s why even if you’ve applied pre-emergent products, you’ll still need a post-emergent solution to deal with breakthroughs.

Another way to prevent weeds from growing in your lawn is to promote healthy and thriving turf. People tend to overlook the power of a thick and healthy lawn, including the fact that it can begin to crowd out weeds on its own.

There are many ways to promote thick and healthy lawn growth including proper mowing, lawn fertilization, irrigation, and ensuring that problems are addressed (such as insect or disease issues). Your goal is to attempt to prevent bare spots where opportunistic weeds will take over. When grass is thick and healthy, weeds have to compete with it for essentials like oxygen, water, and nutrients. Fortunately, a thick and healthy lawn will win out.

But if your lawn is diseased, thinning, or bare, you’ll definitely start to see weeds creeping in.

How Do I Kill Weeds in my Lawn in Texas?

As we’ve said, not all weed growth can be prevented. That’s why you’ll also need effective weed control for grass.

To target weeds, there are different types of weed control products. We’ve already talked a bit about pre-emergent and post-emergent controls. While pre-emergent products work preventatively, post-emergent products are those that work to kill weeds in grass after they’ve already germinated and grown.

But weed controls can be broken down into other categories and types, too.

Let’s dig in a bit more.

Liquid Weed Control

Liquid weed control is applied as a spray on to the lawn. Liquid weed control tends to cover weed leaves more uniformly, and you do not need to water in a liquid product. In fact, you want to avoid watering for several hours so the liquid application can dry on the weed and do its work. Also, save mowing for 24 hours after a weed application so the weed control product can work its way through the plant’s system before any of its leaves are cut off.

Granular Weed Control

This dry weed control is applied using a spreader, and it is effective once it works its way to the soil and is watered either by rain or by running an irrigation system. Granular weed control may be mixed with other lawn care products, such as fertilizer. Granular weed control is a broadcast application and is typically reserved for pre-emergent applications.

Selective Weed Control

Selective weed control is designed to target weeds without damaging surrounding grass. If you’re worried about how to kill weeds without killing grass then this is the answer. Specific treatments are chosen based on weed type. For instance, we have selective weed controls available for nutsedge, which is a very difficult-to-control weed in North Texas lawns.

Non-Selective Weed Control

As you might have suspected, this type of weed control product will kill all plants, including grass. These products can help kill weeds along fence lines or in crevices. But special care should be taken to kill weeds without killing grass when using these types of products.

When Should I Treat My Lawn for Weeds in North Texas?

The timing of weed treatment for the lawn is also important. There is a proper time for these treatments or they aren’t going to work as they’re meant to.

With pre-emergent, for instance, it must be applied prior to germination.

Pre-emergents are really important in the Grassperson program. In our 7-application weed control program, 4 of the controls are pre-emergents, showing just how important we believe they are. Like we explained above, getting ahead of weeds by preventing them in the first place is really the best approach.

Of course, there are different weeds at different times of the year.

  • At Grassperson, during our two applications between September 1st and December 31st, we are putting downfall pre-emergent products that help us to “get ahead” of winter and early spring weeds.
  • Then, between January 1st through the end of March, we are putting down different pre-emergent products (2 more applications) which work to control late spring and summer weeds.

Because weeds are constantly popping up, year-round, we are likely treating them with several different controls during each visit. And we do treat for visible weeds during all seven of our visits (even though we’re performing other services like fertilization, too). Because of the persistent nature of weeds in our region, we are almost always spot-treating as they pop up.

So, to sum it up, the answer to when to treat the lawn for weeds is basically year-round. The bottom line is that you cannot become complacent in this fight.

What is the Best Weed Killer for Lawns in North Texas?

Finally, we want to address the fact that there is no one, single weed control approach that is best. All of what we’ve mentioned above is important. Because weeds in North Texas are so incredibly aggressive, you really do need a multi-product, varied approach to kill weeds in grass.

Of course, it is worth mentioning that the products used by a professional are going to be superior to anything you could pick up at the local hardware store or big box store. A pro will have access to premium, commercial-grade weed control products that are going to do a more effective job at killing weeds.

On top of that, you want to make sure that you’re using a year-round lawn care program that will prevent many weeds from growing in the first place (with pre-emergent controls) but also naturally discourage weed growth by promoting a thick and healthy lawn.
