Q.Colorado Blue Spruce Dying
We planted four 5′ trees in our yard in Albuquerque New Mexico. Three of the four are doing fine. One started turning brown, losing needles and died. We replaced it a year later with another of the same size. Now this tree is dying. This tree is about 20 feet from an adjacent Blue Spruce that is doing fine. What could be causing this tree (at this particular position) to die? They get the same care and are in relatively close proximity. Thank you!

That is strange. Perhaps have the soils tested to see if there is something in the soil at that location that is causing such a dramatic reaction. I would also recommend getting some Miracid by the folks at Miracle Gro. Water the tree with it the next 5 times it needs watering, this helped me save one of mine along with mixing some of a product called Super Thrive into the same water.
