Notice the diversity of plants? And notice how densely this homeowner has planted them? The location of a tree or shrub affects shade patterns and movement of air currents. You can use trees and shrubs to shade the east and west sides of buildings and even air conditioning units. Just think, planting trees that lose leaves on the south side of the house provides shade in summer and warming light in winter.
