Types of Weed Control

Experts have found that there are several different types of weed control for the unique types of weeds that grow around the Texas area. You will need different materials and a strong weed killer for the problem you have. When selecting the best weed killer for Texas lawns, you first need to consider the type of weed control you would like. There are 2 types of weed control you can choose from:

Pre-emergent Weed Control

This type of weed control is when we apply a liquid spray to help prevent weeds from growing in our lawn. This preventive measure is usually done in late fall, late winter, or early spring, just before we expect weeds to start growing.

Post-emergent Weed Control

This is perfect for when weeds are already on your lawn. Something to note though that different weed killers would address the different weeds that grow on your lawn. The first step is to identify the problem and the kind of lawn weeds you are facing.

Liquid vs. Granular Weed Control

When choosing the right weed killer, you need to consider the types of weed killers too. You can choose between Liquid Weed Control or a Granular Weed Control.

Liquid weed control is an easy-to-use option for lawn-owners taking care of their own lawns. It's as easy as spraying it on the lawn and can cover the weed leaves much more evenly. When using this, it is best to avoid watering and mowing for at least 24 hours so the weed control can have enough time to penetrate through all of those pesky weeds.

Granular weed control on the other hand is applied by using a spreader which is effective once it hits the soil and is activated with water. When using this, you will need to wait until the soil is watered by rain or an irrigation system. This is usually used for pre-emergent applications.

Selective vs. Non-selective Weed Control

You can also opt for a more targeted approach to weed control. People usually choose selective weed control when they have lawns that are still full of healthy grass. You can use these weed killers to target specific weeds without damaging any surrounding grass. Non-selective weed control is stronger and would affect or even kill any surrounding plants, including grass. This would be perfect to use if you are going to completely overhaul your lawn or if you can hyper-care application to make sure it won't be touching any other plants or grass that you still want to keep.

Types of Lawn Weeds in Texas

In Texas, there are a few notorious and common weeds that can destroy your lawn. Here are the top 5 that can affect your plants and grass and prevent it from becoming the picture-perfect lawn of your dreams.


Crabgrass is what we usually think of when thinking of lawn weeds. There are the smooth crabgrass and the hairy crabgrass. They usually crop up early to mid-spring and reproduces quickly. If you don't get rid of them immediately, they can completely infiltrate a lawn and grow faster than most grass. Care and maintenance are usually what's needed for this. Crabgrass cannot thrive in dense turfgrass. Prevention is the key here. So, opt for a pre-emergent weed control so that you don't have to dig out all of the crabgrass growth one by one just to control it.


This type of lawn weed can grow in dry soils and grows faster than turfgrass. You can usually notice it shooting up from your lawn in warmer months. The best option for this is to treat them with a post-emergent and selective application to the weeds themselves.

Pos annua

This lawn weed is also known as bluegrass. It can shoot upright and grows annually during the late summer to fall seasons. This is one of the more difficult to control but not impossible. To do so, professionals use both pre-emergent and post-emergent applications to control and prevent this weed from growing in their lawn.


Dallisgrass is a bunch-like, tall seed stalk that can grow in groups. The best way to control these is through post-emergent weed control.


This pretty yellow flower may seem like an ordinary plant but it is actually a fairly common lawn weed that can negatively impact your grass and surrounding plants. These usually come back every summer and would not be fully removed unless a weed killer is applied to the area. The best way to remove them is with post-emergent weed control.

Depending on your needs and the specific weeds that you often encounter in the area, the best weed killer for Texas lawns vary.

So, as you can read, weed killers are great as supplementary care for your lawns but to have a beautiful lawn takes hyper-care throughout the year.

The best way to tackle weeds is to prevent them from ever growing. To do so, you should remember to do three things aside from getting the weed killer ready.

  1. Water deeply but not often. You need to foster the growth of strong, deep roots. To do so, you need to make sure the water is reaching deep into the soil. If you do so, you don't need to water the lawn daily. If you have healthy grass, it has better chances to compete with weeds that want to grow in your lawn.
  2. Keep your grass high. Weeds cannot thrive in shaded areas. They like the sun. So, when mowing, use the first or second highest setting to allow the grass to stay tall and cast a shade on weed seeds before they sprout.
  3. Don't forget to feed your grass. To achieve that lush green lawn, you'll need to keep them healthy and happy. By giving it the right feed, you can help your grass tough out its weed competitors.

With these key habits of taking care of your lawn and the best weed killer for texas laws, you'll be able to achieve lush greenery in no time!
