We have a fairly large area (1/3 acre) of our yard which is almost completely johnson grass. We would like to put buffalo grass and wildflowers in this area, but does anyone know how to get rid of the johnson grass? We have been organic for five years and don't want to use a toxic chemical.

The first step would be to keep it mowed as short as possible. Have you tried spraying with 10% vinegar solution?
