We have been in our house for over a year now, and I am tired of our backyard. The previous owners planted one cherry tree and left it at that. We have a 6' tall cinderblock wall that runs the length of the yard (about 90'), and there is a fairly busy street on the other side. I would like to plant something along the fence that will grow to between 8-10 feet tall to block some sound and provide privacy. We have a good view of the mtns, so I dont want anything too tall. I am trying to decide between some sort of shrubs to grow in a hedgerow, or maybe some climbing ivy on the wall with some well placed trees. I live in Salt Lake City, so its a very dry (we have a sprinkler system) and sunny summer climate. I dont know anything about lansdcaping or shrubs/trees, so any help would be appreciated.
