I have a whole row of Leylands, planted in April, all doing fine. Dear Hubby accidentally nicked one of them today with the weedwacker and the string wrapped the trunk and made a notch all the way around. He fears that the tree will die. It did not bend the trunk, but it did remove the bark in a thin line all the way around. A friend mentioned to me today a similar thing happened while he was growing up and his Mom wrapped a gauze bandage around it and it survived. Is there anything I can do to help heal the wound on this young tree? Any suggestions are greatly appreciated!
