Wild grass in my lawn #744399

Asked April 14, 2021, 8:14 PM EDT

Last fall, we spilled some wild bird seed in the lawn.  Now we have a taller, bright green wide blade grass taking over.  How can we kill this without destroying the bluegrass lawn?

Expert Response

Hello

Identifying grasses requires close examination of tiny details, usually under magnification. You may send whole plant samples, including the roots attached, to MSU Plant and Pest Diagnostics lab for identification. Include pictures of the whole plant and of the lawn containing the unknown grass.

If you still have the seeds that were in the feeder, it may help to send a small sample of them, too. If the bird seed package lists what seeds are contained in the mix, that would be helpful to the lab, too.
