As a homeowner, you most likely understand the importance of maintenance. From washing the exterior siding and repairing lost roofing shingles to cleaning the interior regularly, these tasks will all improve the look and function of your home. One area that many homeowners fail to make a priority is their landscaping. Good landscape design can increase your home's value between 5.5 and 12.7 percent, making it a great investment. Of course, knowing what changes and updates to make to your landscaping can be challenging.
