As a homeowner, nothing is more appealing than having a great lawn. We indulge in several maintenance tasks throughout the year to keep the grass green and lush.
Dallisgrass and crabgrass are two popular varieties of weed grasses seen in yards and are often mistaken for one another.
In this post, let us try to understand the differences between the Dallisgrass Vs Crabgrass so that you can identify each and learn what steps you should take to maintain your lawn.
Dallisgrass Vs Crabgrass
It is important to identify the type of weed you have before taking measures to kill them.
Dallisgrass and crabgrass are often seen growing in the yards and look similar.
However, they have several similarities and differences that you should be aware of. Both these are weeds that are unwanted when seen growing on the lawn.
However, Dallisgrass is a preferred pasture grass for ranchers though its seed heads are likely to develop fungus during summer months.
Both Dallisgrass and crabgrass are evading in nature and often difficult to get rid of once they thrive. Dallisgrass, however, can evade a lawnmower because of its tall stalks which can be smooth as well as coarse.
- Being stiff and thick, they can be hazardous for people walking around the yard.
Dallisgrass is also more difficult to control as compared to crabgrass because it grows back from the root system annually while crabgrass sprouts only from the seeds.
Talking about the appearance, Dallisgrass grows in solid bunches while crabgrass spreads in a star-like pattern. Dallisgrass can thrive when nitrogen fertilizers are sprayed in the lawn while crabgrass can be suppressed by other grasses with the use of fertilizers.
How To Tell Crabgrass From Dallisgrass?
If you have different types of weeds in your yard, it is important to know the difference to be able to handle them well. Both crabgrass and Dallisgrass are thriving and full-grown grasses and people often mistake them for each other.
It is possible to prevent crabgrass as it is an annual plant growing from seeds. Dallisgrass, on the other hand, is difficult to prevent and you should tackle the plants as they grow in the yard.
If these two types of weeds grew side by side, it is easy to tell the difference. Dallisgrass is a more upright, taller weed as compared to crabgrass.
The latter has broader leaves and grows closer to the ground, resembling St. Augustine.
However, it is still possible to tell crabgrass from Dallisgrass with the help of the seed head. Crabgrass has fine and small seed heads that grow out of the top of their stem.
Dallisgrass has much bigger seed heads with black spots and grow from the stem side rather than the top.
Dallisgrass is known to produce rhizomes, short underground stems while crabgrass forms a thick mat of weed with clumps of side branches. Crabgrass can take up a variety of forms depending on the surroundings.
However, its blades seem apart and not originating from the central point. The stems and branches grow bigger with time and reach the ground to spread out in a star pattern.
What Does Dallisgrass Look Like?
A perennial grass native to South America, Dallisgrass is known to produce seeds during its lifecycle. It can be easily recognized by the seed head that generally escapes a mower reel.
The grass grows in a bunch and has a coarse texture. It grows quickly in a vertical structure and is thicker and stiffer than most other types of grasses.
What makes Dallisgrass stand out from others is its grayish-green tone and hair growing on the leaf blade and collar. Dallisgrass is different from other bunch-type grasses as it produces short rhizomes that increase the diameter of the plant by growing as an underground stem.
Why Is Crabgrass Bad?
Crabgrass is a grass variety but not a turf-type grass used to create lawns. It is an annual grass that grows during the spring, summer and fall and dies in the cold. It is bad because it looks ugly and dominates the lawn throughout the season.
Crabgrass creates the biggest problem in the summer. Grasses grown in the lawn grow vigorously during the fall and spring. In the summer months, they slow down and even go dormant.
Crabgrass, however, thrives in summer and can easily establish itself on the lawn. It is an opportunistic plant that grows in bare yard areas and crowds good plants that are weak due to some problems.
Apart from this, crabgrass dies during the frost and turns brown, making the yard ugly. Each plant drops thousands of seeds which continue their lifecycle during the spring.
Is Crabgrass Bad For Dogs?
Most pet owners are concerned about the safety of their pets eating grass. Dogs seem to love the taste of crabgrass and like grazing this weed when roaming around the yard.
There are several reasons dogs eat grass and they are generally seen feeding on grasses when having an upset stomach.
Crabgrass is not a toxic plant and therefore not bad for dogs. While some of the grasses can lead to conditions like diarrhea and stomach irritation, crabgrass is mostly safe when fed to dogs and should not cause any health issues.
In rare cases, crabgrass can result in adverse effects on a dog. We hope this article helps you identify what type of weed you have in the yard and what measures can help you eliminate them for a healthy, weed-free lawn.
