When landscaping with shrubs and trees, the grower should choose varieties that grow well in the soil conditions, light and climate. The mature size of the shrub or tree matters more than its current size. Size, color and leaf texture should be balanced with other elements of the landscape.
Landscaping involves more than simply choosing shrubs and trees. Sketching the landscape with a scaled drawing helps in choosing the location of plants and shrubs. Knowing the full size of each plant helps keep the landscaping proportional. A large tree makes other elements of the landscape seem much smaller.
The size is also important in the placement. Factors such as buildings, fences and electric lines can affect the choice of a tree or shrub for a space. As the tree or shrub grows, the branches and roots can interfere with these existing structures. Placing a large shrub or tree near the driveway or sidewalk also becomes a safety hazard because of the obstructed view.
Shrubs and trees also come in different shapes that affect their look within the landscape. Examples of tree and shrub shapes include pyramidal, round, columnar, weeping and oval. Trees and shrubs can introduce color into the landscape if the foliage turns different colors at different times in the growth cycle. Evergreen trees and shrubs are a way to add greenery to the landscape year round.
