Hello, New to the forum. I have a young willow that appears to be diseased, or else is being eaten by bugs (tho I never notice any insects on it). The leaves appear to be doing well, but the bark appears to be simply disintigrating & splintering. It's worse at the bottom but appears to be progressively spreading up. I've attached a couple of pics. I'm inexperienced to say the least when it comes to plants in general. Any help would be appreciated.
