We have a beloved shrub on our porch that has grown tall like a tree (in Utah). It has become infested with something, and I don't know where to start. What kind of shrub is this? What kind of bug/disease is it? It's taken over half or more of the shrub, can it be saved? My husband tried spraying it once to no avail. Also, in the photos you can't tell, but the white bug-like things don't move. They're stuck on like scales. Any help is much appreciated!
