We have a very small back yard which is up a small hill from another home in our development. To provide privacy, economically, would you recommend lilac bushes for a 53′ long span to provide privacy so we cannot look directly down into their home. Do you have any better recommendation. Cost is a factor.
Lilacs would work. You could also create an evergreen hedge using arborvitae. For a very tall hedge, you could plant Green Giant Arborvitae Here’s more information on them.

Besides being large, they are also not attractive to deer.
