spruce disease needles
i bought for Christmas a young Blue Spruce and these days i notice that some of the needles are changing color and fell off the tree.
the inside of the tree is still healthy as i can see.
what is this, and what can i do ?

Thank you for your question about your blue spruce tree, Chris. I'm not sure where you and your tree are (Northern or Southern hemisphere), so I don't know whether it's almost spring or almost fall where you are. I can see some webs on the left picture, which might be a sign of spruce spider mites, which are described here. Without knowing your season, I can't tell you which life stage the mite would be in now.
The yellowing of the needles can be a sign of several diseases, all detailed here. To identify which it might be, you'll need to use a magnifying glass to look for fungal spores. Alternatively, you can cut off a branch (with both yellowing and webs) and take it to your local agricultural college for identification. I hope this proves helpful. Good luck!
Thanks so much for your reply!
i am from Greece, and now we have February...
i will follow your advices...
Have a nice evening!
Good luck, Chris!
