Summary: A walk down a country lane can demonstrate what a difference trees and natural features can make to one’s comfort. The cool shade of overhanging maples is a welcome relief from the midday sun of July, yet on a bright winter’s day, sunshine streaming through the bare branches warms the body and soul. Similarly, the sheltering effects of pines and hemlocks is quickly realized when one steps from their protection and strolls out into an open field on a windy winter’s day. A well-designed homesite will incorporate these features in landscape design. An energy-efficient landscape has been proven to cut home heating and cooling costs by up to 30 percent. A house nestled against a hillside or next to a stand of pines is often spared the brunt of chilly winter winds, and trees that were spared the bulldozer blade during construction can reduce or eliminate the need for air-conditioning in the summer. If your home doesn’t have a natural windbreak, many evergreens are suitable for installation. White pine, Canadian hemlock, and Norway spruce are often used for this purpose. Plant them 4 to 6 feet apart in a staggered row. Generally speaking, wind velocity will be reduced from a distance up to five times the height of the plant. Topping each tree every year will keep the height right and will also force it to stay bushy. Another row of evergreens established along a walk or driveway will stop drifting snow and eliminate some plowing or shoveling. The strategic use of shade trees in a landscape may increase a property’s value by up to 20 percent and also provide energy savings. Planted in front of a porch or patio area on the south side of a house, they provide a pleasant place for outdoor activities. In the summer, the dense canopies of trees like maples and oaks keep these places cool, yet when leafless in the spring, winter, and fall, they allow sunshine to stream in. A pergola or trellis covered with grapes or a flowering vine can give attractive shade to windows or glass patio doors in summer, yet allow light to shine through when the sun is lower in the sky during the winter.
