Is my tree safe?
Trees are essential to the ecosystem and add value to any property. However, trees can become liabilities if they fall and injure people or damage property. Proper maintenance will help identify when a tree becomes dangerous. Evaluating the seriousness of a trees condition is best done by a professional ISA Certified Arborist.
What should I do if I think my tree has an insect and/or disease problems?
