Torpedo grass is a weed that can be difficult to eliminate from your lawn. It can spread quickly and choke out desirable plants, making it essential to control torpedo grass quickly. This weed looks like many other types of grass, with broad, flat blades. Torpedo grass is often mistaken for crabgrass, but they are different. Crabgrass has a more sprawling growth habit and wider leaves, while torpedo grass tends to have more upright growth and narrower leaves.
Keeping your lawn grass green in winter is an excellent way to prevent the growth of torpedo grass. Make sure to mow your lawn regularly and keep it at a height of two inches or higher, as this will help create an environment that is unfriendly to weeds such as torpedo grass.
Signs You Have Torpedo Grass
Before getting rid of torpedo grass, you should be able to identify it. This invasive weed is recognizable for its flat, oval-shaped leaves that grow in a fan shape. The blades of the grass are usually around an inch long and vividly green. It also has flowers at the end of each blade that range from light pink to white. In addition, torpedo grass has an extensive root system that can reach up to 10 feet in length, making it difficult to remove from the ground.
Dangers of Torpedo Grass
Torpedo grass is known for crowding out other plants, as it can quickly spread and take over a lawn. Like crabgrass, torpedo grass can quickly spread and take over a lawn, making it difficult to manage. The weed can also survive in hot and dry climates and does not require much attention or maintenance to thrive. It can grow up to two feet tall if left unchecked, making it difficult to walk across the lawn. In addition, torpedo grass has a shallow root system, which can lead to soil erosion if it is left unchecked.
Effective Ways of Getting Rid of Torpedo Grass
The most effective way to get rid of torpedograss is with post-emergent herbicides like quinclorac or glyphosate. Applying post-emergent herbicides is also a lower-cost option to control torpedograss. You can use either selective post-emergents or non-selective post-emergent weed killers to control torpedograss. Effective herbicides for torpedo grass include glyphosate, quinclorac, and fluazifop. Total eradication of torpedo grass requires multiple applications of systemic herbicides over several seasons and persistent, multi-year efforts using targeted herbicides and mechanical removal. You can spot treat torpedograss with glyphosate, but it will also kill your grass or most any other plant you hit with it. Watering your lawn adequately before applying herbicides can improve their effectiveness against torpedograss. Using selective herbicides can help control torpedograss without harming desirable grass types like Zoysia and Bermuda. Regular lawn maintenance is essential to prevent the spread of torpedograss and other weeds.
In the natural control subsection, applying mulch can help suppress torpedo grass growth, although it may still poke through.
a) Mechanical Control:
The most effective way to get rid of torpedo grass is through mechanical control, which involves physical removal. This means digging the weeds and their roots with a shovel or tool. It’s essential to ensure that you remove as much of the weed as possible. Otherwise, it will just grow back again later.
b) Chemical Control:
Chemical control is also an option if you’d rather not dig up the weeds. Several herbicides can eliminate torpedoes in zoysia grass, though it’s essential to read the labels carefully and follow directions. Be sure to use them according to the label instructions to avoid potential damage to your lawn or other plants.
c) Natural Control:
If you’d prefer a more natural approach, there are several options to get rid of torpedo grass. For example, adding mulch around your lawn can help reduce the amount of sunlight and water the weeds can access. You can also use organic materials like vinegar or citrus oil to kill the weeds.
Professional Removal Options
If you’re finding it challenging to control torpedo grass on your own, it might be time to consider professional removal options. Professionals have the expertise and tools necessary to effectively eliminate this invasive grass from your lawn. Here are some methods they might use:
- Chemical Control: Professionals can apply a selective grass killer or a non-selective herbicide to target torpedo grass. This method is highly effective but may require multiple applications to ensure complete eradication.
- Manual Removal: For smaller infestations, professionals might opt for manual removal. This involves digging up the torpedo grass and its rhizomes using specialized tools. While this method is labor-intensive and time-consuming, it can be very effective in preventing the spread of broken plants and ensuring the weed does not return.
- Lawn Renovation: In severe cases, a complete lawn renovation might be necessary. This involves killing off the existing lawn and starting fresh with new grass or sod. Although this method is costly, it is highly effective in eliminating torpedo grass and preventing its return.
Choosing a professional with experience in removing invasive grasses like torpedo grass is crucial. They can assess the extent of the infestation and recommend the best removal method. Additionally, they can provide guidance on how to keep your lawn grass green and prevent the return of torpedo grass while maintaining a healthy, beautiful lawn.
By understanding the impact of torpedo grass and considering professional removal options, you can take the necessary steps to reclaim your lawn and keep it free from this stubborn grassy weed.
Prevention and Maintenance
Preventing torpedo grass from invading your lawn requires regular maintenance and attention to detail. Here are some tips to help you keep this invasive grass at bay:
- Maintain a Healthy Lawn: A robust and healthy lawn is your first line of defense against torpedo grass. Regular mowing, proper watering, and fertilization practices can create an environment where torpedo grass and other grassy weeds struggle to thrive. Aim to keep your lawn grass, such as Bermuda grass or St. Augustine, in optimal condition.
- Use a Pre-Emergent Herbicide: While pre-emergent herbicides may not be specifically effective against torpedo grass, they can help prevent other grassy weeds from germinating. This reduces the overall weed pressure on your lawn, making it easier to manage torpedo grass.
- Monitor Your Lawn Regularly: Regular inspections are crucial. Keep an eye out for the distinctive flat, oval-shaped leaves of torpedo grass. Manually removing torpedo grass as soon as you spot it can prevent it from spreading and becoming a bigger problem.
- Improve Soil Drainage: Torpedo grass thrives in wet environments. Improving soil drainage can make your lawn less hospitable to this invasive weed. Consider aerating your lawn and ensuring proper water runoff to keep the soil from becoming too saturated.
- Use a Selective Grass Killer: If you do find torpedo grass in your lawn, using a selective grass killer can help. Products are designed to target specific weeds without harming your desirable plants. Always follow the label instructions to ensure effective and safe application.
By following these prevention and maintenance tips, you can successfully manage torpedo grass and keep your lawn looking its best.

Frequently Asked Questions
What is the most effective way to get rid of torpedo grass?
The most effective way to get rid of torpedo grass is by using post-emergent herbicides such as quinclorac or glyphosate. These systemic herbicides require multiple applications over several seasons for total eradication. Combining chemical treatments with mechanical removal, like digging out the roots, improves success.
Can I use pre-emergent herbicides to prevent torpedo grass?
No, pre-emergent herbicides are generally ineffective against torpedo grass because it spreads mainly through rhizomes and does not produce viable seeds. Prevention is better achieved by maintaining a thick, healthy lawn and proper lawn care practices.
Will hand-pulling torpedo grass work in my lawn?
Hand-pulling torpedo grass is only effective on young plants in landscape beds. Because torpedo grass spreads through extensive rhizomes that can regrow from small fragments, hand-pulling in lawns is usually ineffective. Mechanical removal combined with herbicides is recommended.
How can I prevent torpedo grass from invading my lawn?
Prevent torpedo grass by maintaining a dense, healthy lawn with regular mowing and watering. Avoid disturbing soil unnecessarily, as torpedo grass thrives in disturbed areas. Also, clean lawn equipment regularly to prevent spreading rhizome fragments, and consider professional lawn care services for ongoing maintenance.
