I have three Colorado Spruce - one's definitely a blue, the other two not sure of. Almost twenty years old. This year I noticed browning of the branches beginning on the edges and working up to the trunk. Not the normal browning you see in old trees that naturally happens in the middle. This is not really 'brown', either - more orange. This begins with the bottom branches and works its way up. And not all bottom branches are afflicted. So far, no needle shed. But they look like hell and I'm afraid they are sick. I checked out diseases - cytospora canker (don't see anything indicative), gall aphids (ditto), Adelges Cooleyi (mites - don't see any). DH is spazzing over our investment losses and refuses to get an arborist out here right now. I'm spazzing over losing these trees. Thought maybe this place would be a good place to cry and see if anyone has experienced anything like this.
