I recently rescued this tree from a pot full of mud that barely drained. After cleaning the roots and transfering it to better soil i found out that it had a white/orange ring around the trunk where it used to meet the mud. It looks like a powdery growth. I also saw a few little holes in the trunk towards the base of the trunk. My first thought was rot from bad drainage but im still not sure what this stuff is and how to treat it. Any advice would greatly help
