I have a lawn that has the start of a wire grass infestation. It was sodded last year and I am with the understanding that wire grass cannot be "cut out" It must be sprayed and killed. So my question is... what is a good product to spray to eliminate wire grass but NOT the sod. By the way, the sod is K31 tall fescue. Thanks for the info. Most people around here kill the whole yard and start all over. There has to be an easier way.
