Alberta Spruce Tree Turning Brown

We had a "dwarf" Alberta spruce that outgrew it's space after 15 years. We moved it and replaced it with a smaller one last year that browned and died. We replaced that with another this past summer and unfortunately that too is dying. The needles are browning and fall off when shaken.

I've seen several posts that say it could be spider mites (although one says they are resistant). I'm willing to try anything (although at this time of year - December) may be out of luck.

Several folks have sprayed for the mites. Can you provide info on what you sprayed with? Any other suggestions will be gratefully accepted as we love having a tree there and would hate to replace it with something else.

Use Horticultural oil in April & then again in Mid May. Using it in the winter can cause die back.
