Blue Spruce needle drop
Bring in a living sample limb that is about 18" long, showing damaged and living tissue to your local extension office. In Scott Co., Kentucky, we are located at 1130 Cincinnati Road, Georgetown. From that sample and questions you answer, it can be determined what may be wrong with your tree. I do not make recommendations for pesticides (includes all, i.e., insecticides, herbicides, fungicides, etc) with out identifying the problem.
