I'm bidding on a apartment complex that has man made barrier from the road. Its basically dirt pile 5 ft tall and about 200 yards with a pretty steep incline. I was hoping to save some time by just making my guys trim it by using a growth regulator. Problem is I have never used one and want to make sure it will work, and two, that it will allow the area to keeps its color so it looks the same as the other property. From what I am reading, it looks like Embark is the way to go. Oh the grass type is centipede. What are your guys' opinions?
