This weekend, we changed tactics. While I firmly believe that pulling out the Yaupon by the roots is the best way to control the Yaupon, it is just taking us way too long. We've changed our strategy. Now we are going to cut it off at ground level and fight it with mowing, burning and herbicides when it returns. Here's a couple of before and after pics of some areas we recently worked on.
This view is 180 degrees from the previous two pics, basically turning around and looking the other direction.
