some 20 years ago my sister gave me picea pungens for my raised heather garden. Like you I didnt want to lose it and, like you again, was prepared buy another when it started to suffer ....as it did.
i had reservations because I thought my soil was too alkaline for it. an acid soil or at least a neutral soil is needed I think.
however, looking at your pictures I think you have over watered it.......??? are you still watering it?
don't think this is the reason for it but picea mite can defoliate these plants.....any accummulations of yellow/brown needles at the base?
