Hello; I have 20 Holly Bushes in front of my house (Blue Princess) they were doing great until they came up with a "cottoney" like substance on them. Some of them are turning brown too and I think we lost one. Some one told us to remove the tree in the front of the house that they were getting this from the tree that was dieing (an old oak tree) we did this and they are really no better. I am at my wits end and would love some opinions on what to do with them. Thank you!!!!
