Trunk chop from hell. Shaving down to live tissue, what should I expect now?

So, kind of a funny story. I was working with a local bonsai guy who is quite prolific in the bonsai social webs, in the “bonsai is easy” camp. He’s really proud of how he’s this bonsai maverick who breaks all the rules. He’s also an extremely kind and generous person so I don’t fault him for any of it. At the end of our meeting, he says, “Well, do you want to work on something together?” “Hell yes!” And I go through his container stock and pick out a Zelkova with a funky monstrous nebari for a Shohin.

He asks me, “Ok. What do you want to do with it?” I point out a front, walk through a line, primary branches. He says, “Sure, that would be the standard thing. But here we break rules.” I ask, “Ok, what do you see?” Instantly, he replies, “Chop it off”. Its July.

So we get the sawsall. After the flat cut, too low, “Cut paste?” “Nah.” “Bonsai soil.” “Nah, just nursery stuff.”

Well I had to break with the rule breaking with that one. I brought it home and at least put it in 1:1:1 bonsai soil. The brutal summer went fine. No Hokidachi glory, but one runner did emerge over the Fall. A miracle. That was last year.

Ok. Now with the questions. At this point Im just experimenting with this tree.

First, As you can imagine, without cut paste, the cut site brutally dried out in middle of the Summer when we did this thing at a completely incorrect time. Don’t we want to do really Early Spring for trunk chops, especially on species that move a lot of water? When trying to shave down the callous angle, I was surprised at how far down I had to go (pictured). I got good phloem and cambium but it was weird, very uneven and I had to cut a deep angle to find a consistent ring of it. What should I expect for budding ?

Second, I smoothed cutpaste over the fresh wound and live tissue, but buds won’t form there on the live tissue line, right? The healthy tissue, covered by cut paste, is it just being exposed for callous development, rolling over the wound site? I expect to come back and re-activate the tissue maybe in mid-July and then again in Fall.

Thirdly, if buds don’t form around the cut paste perimeter because they are occluded by cut paste, how do you ever get a broom-style of buds around the perimeter?

Desecated Trunk chop

No live tissue in sight

Live tissue at a crazy angle. Is this atypical - a result of the intense dieback from “maverick” decision to not use cut paste in July-August.

Pasted.

The miraculous state of health in this tree, despite the abuse.

That looks about what I would expect based upon what you described. Not a broom, but could be a killer informal upright after several cycles of grow and cut back with a bit more care than the first.

Based on your story that final product is pretty much what I would expect! The convex carving back is exactly how we handle big flat cuts on Bald cypress to get a nice transition and healing as the new leader grows out! You’re definitely on the right track to make it into something in a few years. As suggested just go with less severe cuts now to get taper and you can get a sweet little tree that tells a hard life story!

Thanks for the encouragement!
