Visit a local garden center or nursery to determine what types of evergreen trees are available for the area in which you live. Gather information on tree height, spread, color and other aspects that you will need to make a decision. Consider evergreens such as Leyland cypress and Emerald Green Arborvitae.
Determine the area in the yard or landscape in which trees should be planted to provide a screen. Consider spacing and the number of trees needed based on the trees that are available and do well in your particular area.
Consider how the trees used for the screen will affect the surrounding grass or landscape. Design a plan that will allow for planting trees in such a manner as to not negatively impact other plantings.
Consider the size of the evergreen tree to be purchased. Choose trees that you are capable of moving and planting. Also consider the size of the tree in regard to budget. Remember that larger, more established trees typically are more expensive.
Install the evergreen trees following the plan that was developed. Dig holes for the trees that are twice as wide as the rootball. Place the tree in the hole, making sure the top of the rootball is just below ground level.
Water the rootball thoroughly. Back fill the hole around the rootball with dirt and tamp down firmly with your foot. Continue watering the tree as needed so that the rootball does not dry out and result in the tree dying.
