I line in East TN with a great view of the mountain, only I also have a great view of my neighbors back yard and all his trailers. I'd like to plant green giant arborvitaes to block the view of his trailers. Problem, we are up higher then he is and we have a lot of space between us. We had a arborist/landscaper come out and he couldn't tell us.
Our property line is about where the tinny tree in the photo is.
Thanks
