Sure, you’re referring to this post:
Which stuck with me for a while too. However, I had been root-pruning this tree for several years preparing it for a smaller pot. By the time I repotted it this spring, I only had to cut one heavy root to fit the pot. In effect, it was being ground layered for years leading up to this, so the radial nebari has fine roots coming off each thicker root. Ground layering it again, in my opinion would have been risky due to the rotted back and no guarantee of replicating the existing radial spread. It would have also destroyed the good nebari and base I spent 15 years growing.

The tree is growing plenty strong, and I am happy with the results so far.
You asked what I could do differently, here is a big one. Pots come in a huge variety of sizes, yes, but there are “standard” sizes that tend to be available, and you should begin with the final pot size in mind. This Ikkou pot took a very long time to find, and even then, I wasn’t 100% sure it would work until I actually started repotting. It is 7 3/8” wide. There are plenty of choices in the 6-6.5” range, and in the 10-12” range, but this tree was in a bit of a no-man’s-land.
