Tree dying, possibly disease or bug? (pictures)
I hope this is an appropriate place for this (new member)
I have picture links (photobucket) at the bottom of the post.
The tree appears to be dying. In the pictures you can see the Pussy Willow behind it also appears to be dying, as well as several others around the area. Another smaller tree next to the one that is dying (poplar) also appears to becoming discolored.
I'm posting here because I wanted to see what people who knew what they were talking about think about it. My father (his trees) is being stubborn, and won't call anyone to come out and take a look at them. All of this has happened within the past 2-4 days. Also, the other poplars around it are untouched, even though the trees are close enough to each other that they touch.
Thanks for any input!
