I have bought several balled&burlaped Blue Spruce trees over the last few years. The trees are healthy but they slowly lose their deep blue color and turn mostly green after planting in my soil. I fertilize them with Mir-Acid and that seems to help. The soil at the tree farm is very rocky and mine is not, I think this is part of the problem. Any suggestions to maintain the deep blue color?
