Do You Have Lawn Weeds that Look Like Grass?

Lawn weeds that look like grass.

When you are cultivating a thick, lush lawn, your nemesis is weeds. There are many invasive plants that will try to take over your lawn, choking out your grass if you let them. Weeds come in many varieties, including some lawn weeds that look like grass but can be detrimental to your turf.

What Is a Weed?

What makes one plant desirable and another a “weed?” While there are many different definitions of weeds, there are some specific traits that are associated with these plants. Any plant that is not cultivated could be considered a weed, but most weeds have one or more of these factors:

  • Aggressive and adaptive
  • Rapid spread and reproduction
  • Excessive seed production
  • Hearty seed survival

Dandelions are one of the most common weeds that infiltrate lawns, but these look very different from the grass around them. There are also lawn weeds that look like grass, but do not provide the soft carpet that most people prefer for their lawn.

6 Common Weeds That Look Like Grass

The first step to fighting weeds in your lawn is identifying them. While broadleaf weeds like clover and dandelions are easier to spot, there are characteristics that make grassy weeds stand out from your cultivated grass. Once you know what weed is trying to take over your lawn, you can begin weed control.

2. Crabgrass
One of the most common grassy weeds is crabgrass. This weed has wider blades then typical turf grass, and it grows in clumps with blades that grow out rather than up. Crabgrass is very invasive, and it can spread quickly through your lawn. It is important to catch it early and remove it from your yard.
3. Quackgrass
Creeping grass, or quackgrass, is a tall grassy weed that can be difficult to remove once it takes hold in your lawn. The tall, pointed blades grow quickly and can reach three feet tall. This weed reproduces underground, making it hard to control unless you manually remove the weed and its root system.
4. Green Foxtail
If you see clumps of flat blade grass with tuffs of furry heads of seed, you may have green foxtail in your lawn. This is one of the common lawn weeds that look like grass but are a menace once they show up in your yard. This weed produces a copious number of seeds, allowing it to spread quickly once it arrives.
5. Nutsedge
Nutsedge is identified by V-shaped triangular blades that often grow with three blades on a stem. If you find this weed in your lawn, you will want to begin a thorough weed control campaign. These weeds reproduce underground and by seeds in the air, making them a nuisance that is difficult to control.
6. Annual Bluegrass
While many people plant varieties of bluegrass for their lawn, annual bluegrass is an aggressive weed that you do not want in your yard. It grows in clumps of flat, light green blades with a curved, pointed top. Annual bluegrass is one of the most common lawn weeds that look like grass and one of the hardest to control.

Eradicating Grassy Weeds

Once you identify a grassy weed, you want to begin a control program. There are an estimated 3,000 or more species of weeds, and each has different ways for control. You will want to research the particular weed to determine the best way to eradicate it from your lawn. Some options include:

  • Manually removing. Some weeds that look like grass can be pulled out – wild onion and garlic are good examples. However, others have extensive root systems that make it difficult to manually remove these weeds.
  • Herbicides. There are many herbicides that can be used to control weeds. There are both pre-emergent and post-emergent chemicals that can target specific weeds.
  • Natural weed control. If you do not like using chemicals, there are some natural weed control products that can be used to control some weeds.
  • Strengthen your lawn. Keeping your grass healthy is the best way to fight off weeds. Mulching, fertilizing, watering and cultivating your grass can help keep out weeds from your lawn as well as improve its appearance.
