blue spruce losing needles
I live in Southern Illinois. I have a blue spruce that is about 15-16 years old. It was healthy and growing good until last year. I started noticing that it was losing its needles. I looked up into the tree and noticed that it doesn't appear to be regrowing the needles. Any idea what the problem could be?
