If you look at the picture, the tree on the right is the tree they cut down last week. The tree on the left is a different tree in a different yard. The "dead" tree seemed great ?last year? as far as I can recall (not sure really), but this year as you can see it had no leaves, so they cut it down. I took a picture before they cut it down in hopes I could get feedback from anyone. My own theory is trees age in a certain way, and this "dead" tree is not aging normally due to the branch structure of a more youthful tree. I think that the company doing my neighbor's lawn put down some sort of weed killer that hurt this tree and not the grass. Thanks in advance for any thoughts!!!
