If anybody has any ideas whats going on with this evergreen tree Please help. The customer has a line of trees in her backyard and this is the only tree that looks like this. The rest are ok. The customer also said she had somebody else take a look at them and said that if the tree roots grow over a buried power line it can cause this? There is some buried power lines in her back yard. The pic shows the difference between the trees. Could it be a lack of iron? Any suggestions are appreciated. We are going to go back and take a soil sample and see what the ph is of the soil also.
