I bought this product to kill back this trump tree/vine off of my house. My inconsiderate neighbor planted this trumpet vine on his property years ago, now it looks more like a tree and had grown over the property line onto the roof and windows of my home. He does not maintain it. I had to climb a ladder and spray the vine that was on my side of the property line and it has killed it back. It did not kill the entire vine, but killed it back off of my house. Oh, I used one of those pumping type sprayer with the nozzle like people use to spray for insects.
