Creating a border in your landscape by using shrubs is the natural way to add privacy or section off your yard or garden. There are many different types of shrubs that you can use, depending on the sort of border you want to make. The types of shrubs you use will also depend on the area you live in and the climate of the area. When designing your border, you need to consider not only the climate, but how high and how wide you want the border. Some plants will grow into full and dense shrubs while others will be somewhat sparse with long thin branches.
