I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I think based on your description that they are dead. The guava I assume wasn't transplanted and still had living roots so it respouted. These probably just suffered to much transplant shock to make it. If you like you can wait another month just to be sure but if there is any regrowth it will likely be at the base of the tree.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
