Japanese maple nebari advice

[Dcj6311]

Any advice on number one how and where to post on this site and if I’m doing it right then I need advice on how to fix the roots on this maple and curious if anyone knew what causes the roots to do this they flare out and go straight down almost like a claw
The tree was labeled shishi yatsabusa but comparing to others online it doesn’t look anything like one

Not sure on the cultivar, only an experienced maple grower could possibly identify, then it’s only a guess if you don't trust the tag or nursery.

But it looks like the maple is grafted high on the trunk. You can keep the tree as is and attempt to flatten the root base over time or attempt an air layer above the graft. If you have never attempted an air layer, I would suggest practicing on less expensive material first.
One other thing, you could also try cuttings from the tree, they are pretty easy on maples after they harden off in the spring.
Many different ways to accomplish cuttings on a maple, just search the site.
Thanks

The roots are like that most likely because the tree has been grown out in round, tall nursery containers where the strong roots tend to grow straight down. Fixing them will be difficult and time consuming. It’s also a grafted tree which is inherently not ideal. I personally would recommend studying up on ground layering which would, if done correctly, give the tree a completely new and, most likely, much better nebari. It’s not difficult, either. Anyway, good luck with your tree.
