Commonly used as lawn grass in warmer areas and as an ornamental grass in cooler regions, dallisgrass is tolerant of a wide range of soil types and can survive in both dry and wet conditions.

The warm-season dallisgrass is very drought-tolerant and is an excellent choice for areas with low water availability.  It has a deep root system, making it resistant to erosion and damage from wind and heavy rains.

Dallisgrass can be mowed and is an ideal grass for areas that experience extreme temperatures since it does not go dormant during cold weather.

It is also tolerant of high levels of salinity, making it an excellent choice for coastal areas. For those who want a lush, green lawn without the need for frequent watering, dallisgrass is a perfect choice.

Not only is it a hardy and drought-resistant grass, but it also has a deep root system that makes it resistant to wind and heavy rains.

How Do I Identify Dallisgrass?

Dallisgrass is a warm-season perennial grass that is relatively easy to identify due to its distinctive, coarse texture and purplish-green color.

This upright grass can reach up to 3 feet tall and is characterized by its flat, wide leaves that are rough on top and hairy on the underside.

Additionally, its seedheads are purplish-green and have three to six spikes. Dallisgrass is also recognizable by its thick, white rhizomes which spread rapidly, allowing it to quickly form dense mats.

The most effective way to identify dallisgrass is to observe its growth habit, as it usually grows in large, dense clumps.

If you are looking for grass to add to your garden, dallisgrass is a great choice due to its rapid growth and easy identification.

Dallisgrass is a perennial warm-season grass native to South America that is easily recognizable by its distinctive gray-green color and long, flat, pointed leaves.

It is a C4 plant, meaning it is adapted to survive in hot, dry conditions and reproduces by seed. The seeds germinate in the spring, and the plants can grow rapidly when temperatures are warm.

Dallisgrass is also able to spread via underground stems, making it difficult to control. In order to successfully manage dallisgrass, it is important to mow regularly and use herbicides to prevent its spread.

Additionally, limiting fertilizer and irrigation can help to prevent it from becoming too invasive. It is essential to take these steps to ensure that dallisgrass is kept in check and does not overtake your yard or garden.


How Do I Inspect For Dallisgrass?

Taking good care of your dallisgrass is essential for keeping it healthy and lush. The first step is to inspect your dallisgrass regularly for signs of stress, such as wilting or discoloration.

It is also important to check for signs of disease or damage, such as patches of dead grass, discolored blades, or damage from insects.

To ensure your dallisgrass is receiving enough water and fertilizer, make sure you’re following the instructions on the label of any products you use.

It is also important to look for signs of pests, such as aphids, mites, or grubs. If you spot any, take the necessary steps to get rid of them.

In addition, examine the roots of your dallisgrass for signs of rot or root rot diseases. If you notice any, take action right away to prevent further damage. To promote healthy growth, you should also trim off any dead or dying grass blades.

Finally, make sure to remove any weeds that are growing in or around your dallisgrass. Additionally, check to make sure the soil pH is optimal for dallisgrass growth. If it isn’t, you can adjust it by adding lime or sulfur to the soil.

How Do I Treat Dallisgrass?

Dallisgrass is a common weed in many warm-season types of grass. It can be difficult to treat and often requires chemical herbicides for successful eradication.

Glyphosate and 2,4-D are the most common chemical herbicides used to treat dallisgrass, however, it is important to read and follow the instructions on the label before applying.

For best results, apply the herbicide when the plant is actively growing. To help ensure better coverage, it is recommended to mow the grass before applying.

If the infestation is severe, two or more applications of the herbicide may be needed. To reduce the chance of herbicide resistance, it is best to rotate the type of herbicide used.


How Do I Prevent Dallisgrass?

Dallisgrass is a troublesome weed that can invade lawns and spread rapidly. Fortunately, there are several steps you can take to control and prevent its growth.

  • First, it is important to pull out any dallisgrass that is found growing on the lawn. This will help to reduce the spread of the weed, but it is not a complete solution.
  • To help prevent dallisgrass from growing back, it is important to keep the lawn healthy by mowing, fertilizing, and irrigating regularly.
  • However, it is also important to avoid over-watering or over-fertilizing the lawn, as this can actually encourage dallisgrass growth.
  • Another way to help prevent dallisgrass from taking over the lawn is to plant grass varieties that are resistant to dallisgrass. This will help to further reduce the spread of the weed.
  • Additionally, it is also a good idea to apply a pre-emergent herbicide to the lawn in late winter or early spring before the dallisgrass begins to grow. This will help to prevent the weed from taking root.
  • Finally, spot-treat any dallisgrass that is found growing in the lawn with a post-emergent herbicide.

By following these steps, you should be able to keep your lawn free of dallisgrass and maintain a healthy, weed-free lawn.

How Does Dallisgrass Affect Lawns and Gardens?

Dallisgrass is an aggressive, warm-season grass that can quickly spread and overtake a lawn or garden. It is tolerant of poor soil conditions, can handle high heat and drought, and can tolerate heavy foot traffic.

However, this makes it difficult to control and can choke out other desired plants in a garden. Regular mowing, timely fertilization, and hand-pulling of individual plants are the best ways to control dallisgrass.

While it can be a nuisance, it also has some benefits. Dallisgrass helps to stabilize soil, reduce erosion, and can be used as a low-cost lawn substitute.

When deciding whether or not to use dallisgrass, consider the pros and cons. If it will be a problem, it is best to remove it as soon as possible.

If it is desired for its soil stabilization and erosion control benefits, use regular mowing, timely fertilization, and hand-pulling of individual plants to keep it in check.



When it comes to controlling dallisgrass, it is important to take the necessary safety precautions. Wearing protective clothing when handling dallisgrass is a must, as it will shield you from any possible contact with the plant’s irritants.

You should also avoid breathing in any of the dust particles when mowing or cutting the dallisgrass. Gloves should always be worn to protect your hands and eye protection should be worn to prevent any eye irritation.

When using herbicides to control dallisgrass, be sure to follow all label instructions and safety precautions to ensure that the job is done properly.

Taking the time to protect yourself when handling dallisgrass will ensure that you stay safe and healthy. Thank you for reading!
