We had a weeping willow to die in our backyard. It was a privacy tree between my yard and the neighbor's backyard. The tree sets in a lower grade than the yard and gets a lot of the water runoff from the yard. Water tends to stand there. We would like to replace that space with a fast growing, water loving plant that would be good for privacy. The neighbors have what looks like tall cedar trees in their backyard and I would love something like that. Help!
