How to Get Rid of Crabgrass

Crabgrass is one of the most well-known and common weeds that people have. It grows in many different areas of the country and can be more difficult than most to control and eliminate. Here are ways to identify, treat, and prevent crabgrass from taking control of your lawn.  Here is a herbicide application schedule:

Characteristics

  • wide leaf blades
  • blades go outwards from stem in a starlike fashion and fall to the ground
  • likes to grow in bare spots that have high visibility to sunlight
  • germination starts when soil temperature is around 50-60 degrees
  • usually grows faster than the surrounding lawn
  • seed heads finger out from the stem. 
  • 3-7 seed heads

Treatment

Selective Herbicides:

  • Use herbicides that are specifically designed to kill crabgrass and leave the rest of your lawn unharmed. These are called selective herbicides.
  • Make sure to properly identify your grass to make sure that the herbicide is safe for your lawn.  Choose your grass below to filter out products that are not safe for it:
  • Carefully read over the label before application.

Recommended Selective Herbicides:   

Non-Selective Herbicides:

  • Spot treat with non-selective herbicides such as Round-Up.  We recommend this method if you have a small and easily manageable growth of crabgrass in your lawn.
  • When you are spot treating with a non-selective herbicide, be sure to spray when the wind is down and there is no rain because that will limit any drift and run of chemicals to other plants.
  • We recommend this treatment method for smaller areas or lawns with a  small amount of crabgrass.

Recommended Non-Selective Herbicides:   

Prevention

  • Pre-emergent herbicides are the most common and effective method for eliminating crabgrass before they sprout.
  • The key to using these herbicides is timing.
  • The best time to apply is when the crabgrass is germinating in the spring but can also be applied in the fall  

Recommended Pre-Emergent Herbicides:
