You looked out at your lawn and noticed this bit tall weed growing.
After asking around and looking online you discovered you have dallisgrass.
Dallisgrass is a pesky weed that can be annoyingly difficult to control and an unsightly nuisance in lawn areas.
But with persistence and a good plan, there are several methods you can use to get rid of it.
Dallas grass thrives in moist, shady areas and spreads rapidly.
Once it invades, it can take over wide areas or an entire lawn and garden if not treated.
Dallisgrass Identification: What is Dallisgrass?
Identifying Dallisgrass
Dallisgrass is a perennial warm-season grassy weed that prolifically spreads and forms dense patches where it establishes.
This perennial weed is be found in many parts of the United States; but grows most in the southern part of the country.
It was introduced into the United States years and was used as forage on farms and ranches.
Since then dallas grass has spread state to state and become a nuisance in lawns..
Dallis grass thrives in moist environments and can often be found near waterways.
It spreads by seeds and rhizomes, making it hard to manage.
Dallisgrass flowers from late spring to early summer, and produces a grain-like seed head that can spread rapidly.
The weed has a grass-like appearance and a long blade-like leaf that can grow 12 inches in length.
The leaves are long and narrow, and the flowers are small and white.
What Is The Difference Between Dallisgrass and Crabgrass?
People often find it difficult to distinguishing between Dallisgrass and Crabgrass.
They are both grassy types of weeds; but grow significantly differently and have different origins.
Dallisgrass can be found in lawns throughout many parts of the United States.
It is often mistaken for crabgrass, but there are several distinguishing ways to identify it.
The most apparent differences between the two are the growth height and seed heads.
Dallisgrass seed heads are much larger and have a characteristic appearance.
The leaves are also wider and shorter than crabgrass leaves..
Crabgrass vs. Dallisgrass:
Is crabgrass and Dallisgrass the same?
The answer is no. They are different plants, but they share some physiological characteristics.
At first glance, crabgrass and Dallisgrass are both grassy weeds that visually look a lot alike.
However, there are significant differences between the two.
Dallisgrass is a perennial weed that grows in patches or dense stands.
Crabgrass is a winter annual weed that also grows in dense patches.
Dallas grass grows best in full sun and well-drained soils.
Crabgrass thrives in full sun to partial shade and moist soils.
Dallis grass
- It has large leaves, which can be up to 12 inches long and 1 inch wide, with a rough texture.
- It spreads by rhizomes, underground stems that spread horizontally and produce new plants.
- Its seed heads look like small cattails or bottlebrushes.
Crabgrass
- Is often used for erosion control or in a mixture with other grasses to create a lawn.
- It spreads by seeds, which can be carried long distances by the wind or water.
- Crabgrass also produces seed heads earlier in the season than dallisgrass and most other weeds.
Overall, both weeds have strikingly similar growth habits.
They can be difficult to get rid of because they reproduce quickly and spread easily through the soil by sending out roots from their stems as they grow.
The Life Cycle of Dallisgrass
Dallisgrass has a life cycle of three stages: germination, vegetative growth, and flowering.
The life cycle can vary dramatically depending on the specific conditions it is growing in.
Generally speaking, dallisgrass goes through the following stages which include germination, vegetative growth, and flowering.
In the spring, Dallisgrass begins to emerge from underground rhizomes; which are horizontal stems that grow just below the surface of the soil.
As the weather warms up and the days become longer; the Dallis grass grows taller and produces leaves and flowers.
The flowers are small and inconspicuous; and are usually green or reddish in color.
They are produced in clusters at the top of the plant, which are pollinated by wind or insects.
After the flowers are pollinated, they produce seeds, which are then dispersed by the wind, birds, animals.
The seeds of Dallisgrass are small, dark, and have a hard, protective coating that allows them to survive in the soil for long periods of time.
In the fall, as the weather begins to cool down, Dallisgrass begins to go dormant and die back.
Its leaves and stems turn brown and dry out, and the plant goes dormant over the winter.
The next spring, the plant begins to grow again from its underground rhizomes, starting the cycle over again..
Does dallisgrass go dormant?
Yes, dallisgrass does go dormant.
It typically goes dormant in the late fall and stays dormant until early spring.
During the dormant period, the grass doesn’t grow or produce flowers.
How to Control Dallisgrass
Dallisgrass can quickly spread and take over a lawn or garden if not managed properly.
Properly controlling invasive weeds like this requires the right combination of cultural, chemical, and physical controls.
Dallisgrass can be systematically controlled with herbicides; but using the correct herbicide and dosage is essential.
The next important task to control these weeds to mow properly and regularly..
Mowing at the correct setting will help curb the life cycle.
This will help reduce the staggering amount of seed production and keep the weed from spreading further.
You can prevent weed infestation from starting by applying pre-emergent herbicide at the right times.
The best time to apply pre-emergents is in early spring, fall, and late winter.
If you cannot treat your lawn turfgrass before the weeds germinate, use post-emergent herbicides to treat your turf.
Selective herbicides can eliminate the weed and not harm certain turfgrass species.
You can do the whole yard or do a spot treatment to the affected areas.
Dallisgrass Weed Control Methods
Dallisgrass weed control can be difficult, but with a bit of knowledge and effort, you can do it.
The most effective way to get rid of dallisgrass is to use a herbicide to treat it early before it becomes established.
The best control method is to prevent seeds from germinating and growing with pre emergents.
Use pre-emergent herbicide on weeds before they get the chance to grow.
Multiple applications may be necessary to eliminate all of the problems effectively.
Here are a few tips for controlling this tough weed.
1. Pull out the plants by hand when they are small. This is best done before they have a chance to set seed.
2. Mow the lawn regularly and keep it well-maintained. Use a good mower; do not mulch the weed back into the yard. This will help to keep it under control.
3.Apply herbicides such as glyphosate or 2,4-D. Be sure to read the label carefully and follow all safety instructions.
