As trees grow and age, their roots expand outward in search of moisture and nutrients. During this process, they may run into obstacles. Tree roots adapt fairly quickly to obstacles and will proceed to grow under a sidewalk, driveway, retainer wall, or the foundation of your home. Another issue may be when soil conditions don't allow for deep growth, you may end up with surface roots. Before cutting the roots away, discover ways to properly manage and prevent tree root problems.
