I moved to a one acre lot in Decatur, Georgia about 6 years ago. The backyard was covered in Kudzu. I kept cutting it back but it grows extremely fast. In a weeks time the vines would extend across my back yard, stretching out (one foot a day) to reach the house. I was able to keep it cut back with the aide of my Stihl Brush Eater blade and kept spraying it with Bayer Brush Killer. I feel I have it somewhat in control at the moment.
