The trees in you landscape have a monetary value, like your house or your car.  Neglect them and they lose value. If you install a skylight in your home it would add value, unless it leaks. Similarly, failing to care for your trees or pruning them incorrectly ultimately effects their value and the value of your property. “Landscaping, especially with trees, can increase property values as much as 20 percent.”—Management Information Services/ICMA  Hiring a certified arborist to care for and prune the trees in your landscape will help maintain or even improve their value.
