We are in Port Townsend, Washington. We have apples, pear, pearapple as well as some evergreens and non. All of them have bright orange on most on the branches in spots, traveling up the trunks as well. Our small town has had a horrible outbreak of a catapiller which only comes every five years or so, apparently, and they build large and horrible caccoons and I'm sure are sucking the very life out of them all. We are in the process of getting this under control but I wonder if a tree who's life is being threatened would be more susseptable to even more disease. But this orange stuff is spreading and fast. It looks a little like peat moss but is orange and not in huge clumps. If it wasn't bright orange we may not have noticed it! What should we do???
