It can also be spread by birds or lawn equipment. Once this grassy weed establishes, it can be challenging to control. But you can eliminate it with time.

This guide contains information on how to get rid of torpedo grass.

You will learn both chemical and mechanical control methods of removing torpedo grass without much hustle.

3 Methods on How to Get Rid of Torpedo Grass in Your Yard

1. Mechanical methods

Torpedo grass loves wet areas. Thus, you will find it thriving during the rainy season. Also, it is likely to occur in recently burned or heavily mowed areas. That’s why it is advisable to establish proper lawn management control methods for torpedo grass.

Techniques such as proper mowing, watering, and fertilization will keep your lawn healthy, thus controlling the invasive torpedo grass. If you mow your grass at the right height, you will be preventing the weed from going to seed.

However, this method will not prevent torpedo grass from spreading since it can creep by rhizomes. In this case, you can consider other techniques such as:

Pulling and digging

If you want to ensure that your existing grass is not damaged, you can consider pulling or digging the torpedo grass. You may require some tools and proper timing to take out the whole plant.

The best time to dig torpedo grass is after rain when the soil is wet and soft. This will help you perform the entire task effectively.

Nevertheless, digging or pulling is not an effective method of getting rid of torpedo grass. If you leave any part of the rhizome behind, the weed will sprout and thrive.

Controlling Torpedo Grass from Your Yard


The burning of torpedo grass is a safe and effective way of having a weed-free yard. Rather than wasting time and money pulling the weeds, you can use a weed burner to get rid of tender seedlings in early summer and spring.

This method works by heating the weed cell, which causes them to burst. By destroying the stem, you will make the weed unable to ingest nutrients and water, causing it to die.

2. Chemical control

The use of herbicides is a more effective method of getting rid of torpedo grass in your yard.

When you decide to use herbicide, it is good to follow the instructions and focus on safety warnings.

With this, you will be sure of its effectiveness and your family’s safety.

You can use Glyphosate herbicides such as Roundup or Celcius WG herbicides if you want to eliminate torpedo grass completely. However, Glyphosate is a non-selective weed killer. Thus, it can destroy any green plant it comes into contact with.

But you can use a fan nozzle setting to spot treat the weed. This will help you kill patches of the grassy weed. When the weed turns brown, remove the entire plant and cover the whole with desirable grass.

3. Solarization method

Do you want to clear weeds on a large area of your lawn? Then, the Solarization method can be a good option. This approach is effective, but it kills all plants and bacteria in the soil.

Thus, this method might not be effective if you want your existing grass to remain in the yard after eliminating the torpedo grass.

However, if you don’t want to use chemicals or pulling methods, you can solarize the soil and develop a lawn from scratch after you finish the whole process.

Here are 6 steps of soil solarization

  • Start by forecasting the weather. The best time to use soil solarization is during the hottest summer months.
  • Remove all vegetation from the soil
  • Level your yard
  • Irrigate the soil
  • Use a transparent plastic sheet to cover the soil
  • Leave the plastic for a month or two

This process will allow the sun to kill the torpedo grass and other weeds. After destroying everything, you need to re-plant immediately to prevent torpedo from invading your yard again.
