Works on Woods Grass
This product works very well on invasive woods grass, which I have a huge problem with right now in my shady lawn. While woods grass is not specifically labeled as one of the grasses it kills, it does a great job of completely suppressing and severely damaging it. It takes 2-3 weeks to turn the woods grass purple, but it's the only product I found that is effective. Use with methylated oil for max effect.
