Trees for Tennessee Landscapes - Maintaining and Protecting
Trees benefit us in many ways. They can also cause major damage when limbs or the whole tree falls on power lines, cars, houses or people. Usually, weakened trees give some warning signs of danger. By learning to recognize the signs and to follow-up with prompt, proper action, you can often manage this risk, saving yourself grief as well as money.
