Dying Oregon Blue trees

Asked May 7, 2013, 9:16 AM EDT

On a hillside neabove my pool, I had planted three Oregon Blue Trees. For an unknown reason, two tress have died, but the third appears to be thriving. My landscaper has no idea what is happening. When the first one died, we replaced it in the same spot, and the replacement died within a year. I was hoping to get some help before I replant another species there. Is such help available?
