Trees for Tennessee Landscapes - Choosing the Right Tree
Screens and hedges are a popular way to create privacy or hide an undesirable view. They can be anything from a section of a fence to individually designed panels, brick walls or a wall of green plant material. Plantings are usually a less expensive way to create privacy than a fence or wall. Screens or hedges also offer additional advantages to many landscapes other than privacy. For example, they can frame a terrace or provide a backdrop to a herbaceous garden or other garden features.
