If bermuda grass is evil, Johnson Grass is EVIL, EVIL, EVIL. It grows at a speed and depth that make bermuda grass look wimpy. You have a choice. You can have a lovely garden with desirable plants of all kinds, or you can have Johnson grass. You cannot have both. Left to its own devices, Johnson grass will crowd out everything else you grow, including bermuda grass. If that doesn't scare you, it should. I would not grow Johnson grass on purpose, not one little sprig. It is insanity to consider letting it grow on your property on purpose. I fight it tooth and nail, and I don't always win, but I keep plugging away. We have a lot less Johnson grass now than we did when we first moved here, but we'll likely never get rid of it all. There are a million theories about how to improve clay. All that has worked for me is the constant addition of organic matter, including growing green manure crops, cover crops and compost crops. You never reach a point where you have improved your clay enough and can stop improving it, because our heat here breaks down all that organic matter much more quickly than we can add more. Johnson grass is not the solution you think it will be. I see more gardens abandoned by late June here because new gardeners underestimated how quickly and how thick Johnson grass would come back and take over their garden plot than for any other reason. After two or three years of letting the Johnson grass take back the garden land, they simply give up gardening. If you ever let Johnson grass get the upper hand, you'll want to give up gardening too because you'll find yourself in a fight you cannot win.

I used to have Cogon grass on my property, it is tough and can grow waist high, its also VERY flammable. It grows very well in fields and under pines, but for some reason it doesn't grow well underneath hardwoods. It took two years worth of spraying RoundUp and it's mostly all gone, although every now and then I'll find a sprig. It's not a problem in lawns, just in areas that don't get mowed frequently.
