Hi! This is my first post on this forum. I have an Oak tree in my front yard. A few years ago this land was cleared for our house. I have no idea what kind of Oak it is. However, I do know that it has a large wound on the Northeast side. I have no idea how it got there as it was like that when the house was built. The trunk is approx 9ft in circumfrance [sp]. The wound is huge. and inside it seems to be rotting. I have pictures and will attempt to include them with my post. Also, I have inclosed pix of the leaves if you need to ID it. The crown seems to be OK from what can tell from the ground. I am a neophite in tree knowledge and would appreciate any advice that I recieve. I am concerned because it is close to the house. I did have an arborist look a it last year. He said, at that time it looked OK, by needed a trim badly and because there is a Y in the trunk we shoud have a cable inserted to give it strength. Last year when he cam out the trunk in the would did not appear to be in the state of decay it is know.
