We have this weeping willow tree in our yard and last year I noticed that it seemed half dead. Like the upper half was dead. Well this year it is coming out again but the upper half of the tree is dead. It has formed new branches off the lower section of the branches leaving the top dead. I started looking at it today and the bark is falling off and I noticed there are holes in the branches from some kind of bug I am assuming? A lot of the roots from the tree are above ground. Like the tree was not planted deep enough to begin with but this tree has been here for over 20 years I would say and last year was the first year it started looking dead. I know the neighbor on the other side does not like the tree and always cuts the hanging limbs off the tree since they hang down onto his yard and he cannot mow.Take a look at the pictures and tell me what you think.
