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?

I called it scale because that is what it looks like, but here is a link to what it was---hemlock woolly adelgid.

I should have treated the hemlock when I discovered this, because I found this infestation a couple of years before it died. Look closely at the limbs to see if you see anything that looks like the pictures on this link. I hope it does not spread to our other hemlocks. I should take a close look at our other ones. We are on the southern margin of where hemlocks will live.
