Weird growth in Amur maple roots

[bonsaichile]

Over the summer, this strange growth appeared on the roots of my Amur maple. Anyone knows what it is? What is the best way to deal with it? Thanks!

So-called 'crown gall' (agrobacterium tumefaciens) maybe ?

It seems like this guy is a goner, then. Too bad

So thia guy wasnt a goner, after all. Last year, I bare rooted it and with a very sharp knife cut out as much of the growth as I could. It stopped growing and sort of callused over, leaving an interesting uro. This year, I chopped the trunk (from 5 ft 8 to 4.5 inches) and now it is beginning to grow out. I am aiming for a shohin sizes broom with this guy, making the uro a focal point.

So I was in bed for about a week with what my dr said it could be a bad cold or COVID-19, but since there are not test for everyone, unless you work in the White House... anyways, this guy has been growing and I am happy with the results. I will apply some wire as soon as the shoots begin to lignify a bit. But now I am wondering how to shorten the internodes. Any suggestions?

I wired it up today, repositioning some branches. I will cut back in a couple of weeks.

Fertilize less, if you're not already doing it. You can restart when the leaves have hardened.

Give those wired branches a bit of movement now that they're wired up!
