Using a wall of evergreens is a simple way to block the view in your yard, but it can also be a boring and unattractive solution to the screening problem. Selecting a single type of plant for your screen is also an invitation to pests and disease that might cause the loss of your privacy when least expected.
There are formal and informal ways to provide privacy with plants. Often clipped hedges and evenly spaced rows of trees or shrubs make a formal statement; while evergreens inter-planted with deciduous plants, grasses and perennials are informal. Decide when you need your privacy most.
We even have “faux” rocks available to cover unsightly utilities.
