eradicating mediterranean grass
I live in Mesa Az and have Mid Iron grass (hybrid Bermuda) as my lawn grass. I do not plant a winter grass.
The mid iron is well cared for and looks great. The problem is an invasion of Mediterranean grass (Schismus Barbatus) that takes over the yard from mid winter to early summer. This is an invasive, self seeding annual grass that is ugly; I want to get rid of it. Is there a pre-emergence herbicide that will eradicate the schismus without killing the mid iron? If so, when is the best time to apply the herbicide.
