I think the micro organisms would be dead by now. They hate to be disturb particularly the root system. There is a very long large root. It goes deep to moisture. If that is cut it’s game over. if everything is done correct, on a transplant of that size its still 50/50. This tree has no chance unfortunately. They take about 6 months to die, they will die slowly. I know your optimistic so I tell you what you can do but it wouldn’t make any difference in this late stage. Go back and gather a meter square of the soil from where it came. Then get a large pot and replant it in there in that soil (Big plastic pot). Then once a week for Two weeks feed it a large bucket (6) litres Water to 300grms of brown sugar. Boil water and dissolve the brown sugar into the bucket. Make sure the water is room temp before pouring on tree. Then feed it monthly. The sugar is for the microbs. strong microns means strong tree. Then feed the tree water but try to use no fluoride in the water. Once a week but make sure there is drainage. In the pot it may concentrate better the soil than in the ground. I still think this is way too late. But it’s the best hope

Lenticels help the tree to breathe, and get rid of wastes -- your sample looks healthy. Now if your tree has dark brown or black turd like growths on the branches or stems -- that is bad, Black Knot. Usually kills the tree.

Thanks for the info. I already dug it up once and added gypsum to the soil. That is how i know the soil is draining well since the bottom of the hole wasn't soggy at all. I also put fertilizer with micros in the soil to remedy any iron deficiency. Hopefully i didn't damage the tree more by trying to help it. I also have a recently transplanted washington navel doing the same thing. I cut all the young fruit off that one to direct energy into root development. I will be patient. Thanks again for the advice.

Yes. We need pictures, please.
