Planting trees around your home can help provide cleaner air, moderate storm runoff, increase property values, reduce energy consumption, and improve human health.
Several studies have shown that on an average street, trees add to a home's sale price and reduce days to sale by 1.7%! Even a single tree raises the value of the home where they are planted and for the neighbors homes.
Properly selected and placed trees can significantly reduce the energy costs for your home. Shade trees, which lose their leaves over the winter, are the perfect choice for the south and west sides of your home. Their shade in the summertime reduces the need for air conditioning and even reduces the amount of reflected heat from the hard surfaces of your yard (drive ways, patios, even walls). During fall and winter months the winter sun can shine through the bare branches of shade trees, allowing whatever warmth it provides into your home. A general guideline for placement of shade trees is 60' from your house on the west side (for shade from 3pm to 7pm in the summer) and 40' from your house on the south side (for shade from 7am to 11am in the summer).
Evergreen trees such as Blue Spruce, Norway Spruce, and White Pine, especially when planted on the north and northwest sides of your home, provide protection from heat loss due to winter winds. Even on other sides of your home, evergreens can provide natural wind-blocking. It is important to plant these trees far enough away so the winter sun can still reach your home.
