Ok tell me more about the scale your hemlock had. I have a large mature hemlock in my back yard on the NE corner of the house. Last summer LOTS of needles turned yellow and fell off. After they all fell off the tree looked find for the rest of the year and looks ok now. Although sparser needles. I looked it over and could not find any bugs or anything suspicious on it that I thought could be causing it. I am so afraid it is going to die, but I don't have the faintest idea what is wrong with it. We had plenty of rain last year and nothing going on that could have did that. Any ideas?
