I was given five plum trees last fall that had been dug up and put into one pot. A few weeks ago I moved the seperate trees into seperate pots. Shortly thereafter I was out of town for a week and left the trees in my garage to keep them out of the heat. On my return I found that the new growth tips turn brown and now are dieing back. Does anyone know what is causing this, and what I can do about it?
