We have had a very long very snowy winter here in New York and my Weeping Blue Atlas Cedar looks like it's dying. It doesn't have its customary blue-ish green color but instead seems very yellow. In addition, there is a significant amount of browning or dead needles. This Cedar is very established, I'd guess at least 25-30 years old and we keep on top of it, trimming as needed, and we don't plant much near it. I'd hate to see it die. Do you have any suggestions on how to get it back to normal? Is it possible the crazy winter we had has put it in shock? Any suggestions would be greatly appreciated.
