Fair question. My approach is informed by trusted sources such as @markyscott and @Lars Grimm reporting good success with rather aggressive root work. If anything my approach, by comparison, seems a lot more "gentle". I think if I was doing a full on repotting every year, cleaning the roots etc it would be a different story altogether and I don't think advisable. But I am just pushing back the rootball while leaving most of it intact. My planned root work schedule depends of course on how the tree does and responds. I am seeing now the tree is pushing nicely. A good sign!
Thank you.
