I have an old tree that has been passed down through a few generations and I was afraid I was killing it to be honest, I did some research and found out that a part of it had died off and needed to be cut. Not wanting to damage the tree and risk losing it I looked into something I knew would work and found this product. It worked great! It cut very easy and my tree is healing fantastically. Cutting left a small scar as I have been told its called but I kinda like it. I hope to keep this tree going for my kids as they grow!
