That does happen to be the shady side if itself but otherwise it's in the middle of the yard with full sunlight.Give it more sunlight.
Evergreens tend not to fill back in where they die back from lack of light. Best bet would be give it full sun and a healthy bit of whatever fertilizer they like.
Tomorrow I will go try and see any of the tiny black spots on the needles. I haven't noticed any discoloration of the needles, it just seems like it is loosing and/or not growing needles except at the tips of the branches.I would bet that it has needle cast. A disease that effects mainly Colorado blue spruce.
Here is an article with some info on needle cast.

If you google needle cast pictures you will see trees that look like yours
Thank you! Any specific products I should look for or stay away from?I do tree disease control for a living, most likely needle cast. When it’s only holding onto one years growth it’s almost always needlecast. The lower branches don’t get as much sun or wind so it usually affects the bottom first. They really need full sun. A few fungicide applications before and after candles push would help a lot. I usually add a Foliar fertilizer as well
I have a good number of Spruce and Scotch pine here. They were all planted decades ago for wind breaks. I noticed one spruce in particular is looking thin of green. Does needle cast spread to the adjacent trees? They are spaced out nicely with the tips barely touching neighboring trees.I do tree disease control for a living, most likely needle cast.

I'm glad you put this thread up. I'm interested in keeping what I have alive. I live in the hills and the wind barriers are well needed.I have what I believe to be a Blue Spruce (kinda blue kinda green) that is getting pretty thin in the middle. Anything I can do to fatten it back up?View attachment 297304 View attachment 297305
Any experience with eucalyptus in the desert?I do tree disease control for a living, most likely needle cast. When it’s only holding onto one years growth it’s almost always needlecast.

Pork products have worked well on me. Especially bacon.I have what I believe to be a Blue Spruce (kinda blue kinda green) that is getting pretty thin in the middle. Anything I can do to fatten it back up?View attachment 297304 View attachment 297305
Do you know how far north it has gone? We have almost nothing but spruce and fir trees on our property. Such a blight would be devastating.Interesting. Spruce are having a hard time in my area. We call these Norway Spruce. My Blues seem ok. I did notice spider mite.
Many are dead. Six on my place.
Sawmill guy saying the same.
Wikipedia said 2 leaves and red-orange bark at the top, I was hoping to find red pine wood almost like red cedar. Also said they are of least concern, so have they already made a full recovery from blight?No idea how wide spread. You may consult you State Ag and forestry friends. If it comes there spraying now be better than later.
Thinking of this more, 4 of the 6 I mentioned are near a perpetual nat gas leak, that may not help them.
The saw mill guy mentioned it when I asked if he saw red pine he said, nope it went from blight like spruce are doing now. Turn of the century (1900s) buildings are full of RP lumber here. Yet I know of none growing.
Red Pine, r e d three letters, three long leafs, red saw dust, great to work with.
I did notice a young live ash tree on the neighbors.
We were talking about spruce?Back to Spruce, they hate wondering topics here lol.
