In the world of tree care there are certainly some right and wrongs. However a large portion of the work provided is dictated by the homeowners personal preferences (particularly in the area of pruning). For instance–a tree that grows on the edge of the grass/tree line often grows at an angle towards the yard and or house. The tree will grow toward the light and often be weight heavy towards the light. Some would elect to remove the tree while others would choose to keep it and do regular pruning to keep the tree safe and healthy.
