My Blue Spruce pine trees seemed to be dying. They are loosing their needles on the bottom 1/3 of the tree. Then the branch goes to a dead stick. I have sprayed them all summer with Sevin or Malathion. But they keep getting worse. I have broke open the branch, but I can't find anything. Is there any hope for these 20 year old trees?

HI Kris, blue spruce get a couple of problems. Spruce spider mites and a couple disease problems rhizospheara needle cast and cytospora. check out this website to look at pix to get a better idea which one it might be. http://www.urbanext.uiuc.edu/focus/index_evergreen.html also may want to contact your local extension office. this is their website. http://web.extension.uiuc.edu/edgar/ hope this helps, Sandy
