Safety Products

Please be sure to read the product label of any insecticide you choose to use to get information on the personal protective safety gear you will need. In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator. We have put together two different safety kits that will make selecting the correct safety gear easier for you.

How to Prevent Quackgrass Weeds

How to Stop Quackgrass from Growing in Your Yard

By DoMyOwn staff

Quackgrass, also known as couch grass, is a grassy weed found in most regions of the United States. It is considered invasive in the Midwestern and Western coastal states. Producing new shoots from late summer through the fall, this cool-season perennial can be hard to control once it appears in a lawn. The best way to stop quackgrass from growing on your property is to prevent the weed from growing in the first place. Read below to learn how.

Step 1

Keep Your Lawn Healthy

The best defense against quackgrass is a healthy lawn, as the weed tends to appear in lawns that have patchy, loamy soil.

The following are ways you can help create a healthy, weed-free lawn:

  • A soil test will help analyze your lawn's soil for missing nutrients. After completing the test, you can then choose a fertilizer that meets your lawn's nutritional needs and apply regularly.
  • Water your lawn regularly, as needed. Water in the morning to allow the water time to dry and to prevent burning in the summer sun.
  • Mow your lawn regularly, keeping the grass blades 1-2 inches long.
  • Aerate your soil once or twice a year to help air and nutrients reach compacted soil.
  • Fill in patchy areas of your lawn or overseed with grass seed.

Check out our Cool Season Lawn Care Schedule for more information on when and how to perform lawn maintenance.

Step 2

Apply a Pre-Emergent Herbicide Treatment

Quackgrass will begin to produce new above-ground shoots in lawns in late summer and through the fall. By applying a pre-emergent herbicide in early summer and again in the fall, you can help keep your lawn healthy and strong by preventing new weed growth.

Choose a pre-emergent herbicide that is labeled for quackgrass and mix in a hand pump or backpack sprayer with water, according to the directions on the label. Then, spray your entire lawn in neat rows to ensure even coverage. You may want to add a temporary spray indicator dye to your mixture to see where the product has and has not been applied.

Be sure to wear personal protective equipment, including gloves, long sleeves, and closed toe shoes when applying. Wait 1-2 hours after your application before allowing pets and children back into the yard.

Quackgrass can be avoided with the right timing and treatment options. If you're not sure if you have quackgrass in your yard, read our Quackgrass Identification Guide before selecting a treatment.
