I have silver dollar eucalyptus trees that are turning brown. I believe that may have been fertilized with fertilizer stakes, only about a quarter of the spike, not the whole thing. I have been watering the plants hoping to flush it out, I've even dug up the trees and moved them to a new location, they are only about 4 feet tall. Any ideas on how to save them would be great. My growing zone is 8, Texas

It is hard to say what may be hurting them. Moving them may not have helped them though, but rather hurt them as they would have been put into transplant shock by the move.
Right now, I would recommend watering daily and treat with a fungicide and a pesticide.
