A well-designed landscape can add beauty to your home and reduce home heating and cooling costs. Plant deciduous trees with high, spreading crowns to the south of your home to block sunlight in the summer and reduce the need for air conditioning. Deciduous trees lose their leaves in the winter, allowing sunlight to warm your home. 

Plant evergreen trees and shrubs with low crowns to block winter winds. Dense evergreen trees and shrubs planted to the north and northwest are the most common type of windbreak and can help lower energy used for home heating.
