Sorry to bring this topic back up, but this summer proved to be relentless for my lawn directly around my house. The fields are fine, but I don't want Johnson Grass around my house. It's unsightly and it chokes out fescue and other desirable lawn grasses. I have tried to manually dig out as much of it as I can, but it's quickly going out of control. I've got a few 10' x 10' patches of it now that are spreading. It would take a month of Sundays to manually dig that all out with a garden spade.
So back to the topic of herbicides.. are there any that I can actually purchase myself that are effective at controlling Johnson Grass but will not harm fescue? I know that's a tall order, but if one exists please list it and I'll buy some.
