Deciduous trees and shrubs should be planted to shade south walls and windows - if there is no overhang to significantly reduce the effects of the sun. Shade trees planted in direct line, drawn at the same angle from the southwest corner, will effectively shade that corner of the home. Coniferous trees should be grouped on the northern and western sides of the house to help block winter winds. When planting trees, it's important to choose the site based on what the tree will look like when it is fully grown. Make sure that there is plenty of room for the tree to grow above and below the ground.
Plant trees away from overhead power lines, driveways and sidewalks.
Remember there are also utilities like sewer, water and electric lines underground. Planting too close to your utility lines can eventually cause problems with your services. Sewer and water lines will only be marked on the city side of the meter. Lines running from the meter to a home are not located by the utility.
