Where did you buy it from?
How long did you have it before you planted it?
If you purchased this spruce from a nursery, and you planted it in a timely manner, (within a few days) this damage is extreme. If you purchased it with lots of missing or dried needles, and already well on its way to this poor condition, I think you shouldn't have purchased this particular spruce. This plant, if confined to a plastic three gallon or five gallon pot looks severely dehydrated. Either you purchased it dehydrated or held it without water for too long of a period of time and it became dehydrated. Or another possibility is that you planted it without watering it thoroughly and let it go for a period of time and still didn't water it well. It would have required deep watering roughly once a week.
I am unsure of what the future might hold for this spruce. But at some point or points, this plant did not receive enough water. The black pot did not cause the damage seen, the lack of water caused the damage.
