Effects
-
Landscape shrubs, trees or hedges are often used to shield homes from damaging winds, sun or noise. According to the U.S. Department of Energy, placing trees and shrubs carefully around your patio can cut energy costs by as much as 25 percent. Evergreen shrubs and trees are the most commonly used windbreaks. Placing these trees with a wall may also help reduce wind speeds and will insulate your home in the winter and summer months.
Types
-
Arborvitae is often seen around decks or patios. Eastern arborvitae reaches 20 to 40 feet in height and thrives in full sun. These evergreens keep their green color throughout the year and tolerate wet or alkaline soils well. Larger evergreens such as Norway spruce are often used as windbreaks and screens. These trees reach 40 to 60 feet in height, although many dwarf varieties are also available. Norway spruce needs room to grow, but its thick foliage and size make it an ideal windbreak for larger yards.

Problems
-
Evergreens such as arborvitae and Norway spruce are favorite sources of food for wildlife such as deer. These trees are also susceptible to damage from scales, mealybugs and needle miners. Perhaps the most damaging insect pest of evergreens is pine needle scales and spruce bud scales. Examine these trees on a regular basis for signs of insect infestations and apply treatments at the first sign of infestation. Spider mites are also a common pest for several types of spruce. These insects can cause serious damage to host trees and even kill heavily infested trees.
Considerations
-
Before placing trees and shrubs in your yard as windbreaks, consider the amount of space you have and the size of trees at maturity. Consider the growth rate of your trees when placing them near patios or walkways.When purchasing trees or shrubs, examine the plant for signs of disease or insect infestations. Avoid purchasing any trees or shrubs that appear unhealthy or diseased. Keep your plants well-hydrated to avoid drought stress.
