|I have three 50' to 75' feet trees that something has eaten the very top bark leaving the underneath to turn black with age. These trees have been here forever and are in a prominent place in our landscape. I would hate to loose them. Please help.|
I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Based on that description alone I cannot determine the cause of the problem. Squirrels will often chew the bark on trees. There is a disease of oaks that causes bark to fall off leaving patches that can be olive or gray or black beneath. I suggest you take some photos to your County Extension Office along with some samples if possible to see if they can identify it and provide a recommended course of action.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
