Planting trees and shrubs around your home will help to reduce your heating and cooling costs. How much it reduces costs depends on your choice of plants and where you locate them.
Trees and shrubs shade people and buildings from the direct rays of the sum. During winter, deciduous trees and shrubs shed their leaves and let the sun’s rays help warm the house. This is an important consideration if you are planting for summer shade on the southern exposure of your house.
Plant Full-Crown Trees,
Not Cone-Shaped for Shade
Maples and other trees with full crowns are best for summer shading. The high brances permit greater visibility and do not block the flow of cooling breezes.
Evergreens’ cone-shaped crowns provide less shade on walls and roofs. Their branches often extend to tfie ground, blocking visibility and the flow of cooling breezes. If planted in the wrong location, they may shield you house from the sun’s warmth in winter.
