In many areas, winter winds come from the north. Plant evergreen trees on the north side of your home to help block the wind. Plant deciduous trees on the other sides of your home. That way, during the summer, their leaves will block the sun, and in winter, the bare branches will allow the sun to enter and heat your home. According to the U.S. Department of Energy, planting trees strategically around your home can help you save up to 25 percent on heating and cooling bills.
