Question
I have a Colorado Blue Spruce planted(3 years)in the corner of my yard (full sun) which is dying. Prior I lost another pine in the same spot over about a 3 year period.  Twenty feet away I have pines doing just fine.  We live in Rosemount, Minnesota soil is sand, clay and dirt more alkaline.  The current pine is yellowing at the top and the needles are becoming brittle.  A few questions:  Can the current pine be saved (7 feet tall)?  Ideas on what might be causing it?  Is there a hardier less sensitive pine that will grow in almost any condition?  Thank you.

Answer
Hi Scott, Colorado blue spruce should do fine there assuming the drainage is good.  They will not stand "wet feet" for any period of time and drainage is the number one cause of death.  It could be insect or disease, but without a close examination, it's hard to tell.  
Take a dying branch and a soil sample by your local garden center.  They should be able to tell you what is wrong and how to prevent it from happening again.
Can it be saved?  Probably not.If it survived, the top is dead, so it will not be an attractive plant.  I would start fresh.  Jim
