Stopping spread of broad leaf grass into kentucky bluegrass lawn?

Asked May 26, 2020, 1:51 PM EDT

I have a beautiful Kentucky bluegrass lawn. My neighbor's lawn has a large expanding patch of a broader leaf grass, that is now threatening to move into my yard. Can you identify the broader leaf grass and is there a way to prevent the spread into my yard?

Anoka County Minnesota

Based upon what we can see in the photos, we think the gassy weed is quackgrass.

The following bulletin describes quackgrass' identifying characteristics and discusses what can be done to control it. To confirm or discount this ID please compare your weed to the one shown in the bulletin.


If you conclude that the weed is not quackgrass, please attach more sharp photos when you reply to this message and we'll take another look.

Thanks, I will examine the root system. I appreciate your help!
