I did cut back one root that had no contact with the soil and so was not feeding the tree. I am looking for suggestions on what to do with the root stub, which is above soil level. Judging from the foliage that the stumps put out I would expect there is good feeder root development and eventually the large roots can be safely cut back to permit potting in a reasonably sized pot. I am still undecided whether to just put this in our landscape where it can be viewed and worked on, or aim to develop it as a bonsai. There are a number of options with this tree. It is actually two trees embraced together, so it would be possible to separate them. I think the right trunk wouldn't look that good alone. It could be a root over rock setting though. The embrace is what appeals to me about the two trees. The large root going to the right with the sprout on it belongs to the rt trunk, not the left one. Well for now, I will just let it grow.No rush, do it gradually. it wont be ready for a bonsai pot for a good while anyway.
Why not try an underneath V notch and pull the root down into the ground and let it grow feeder roots? I have done that successfully with May hawthorn.I did cut back one root that had no contact with the soil and so was not feeding the tree.

Interesting.That probably would have worked better before I shortened that root. There is not much room to work on the underside, because it is right above a large root coming from the rt. trunk that wraps around the left trunk. Maybe by starting with a drill hole that would let a small saw into the root it could be done.Why not try an underneath V notch and pull the root down into the ground and let it grow feeder roots?

You can use a wire saw.Interesting.That probably would have worked better before I shortened that root.

hard to tell, maybe I would nibble away at it with knob cutters to get it flush with the soil or i'd remove it completely and maybe make a uro. hard to tell with these pics. your call mate.I did cut back one root that had no contact with the soil and so was not feeding the tree.

What is a uro?hard to tell, maybe I would nibble away at it with knob cutters to get it flush with the soil or i'd remove it completely and maybe make a uro. hard to tell with these pics. your call mate.
a small hollowWhat is a uro?
OK, I see your point. I just put it in the grow box to go a season and see if it recovers from the collection and grows more feeder roots. If transplanted to a pot, I guess I would still have the option of setting it deeper. The back side is a bit bizarre,that root going to the rt looks pregnant. It is what it is.Ok but again, looking at it now, I might have just buried the tree deeper. Sometimes its tricky to give people advice on here because usually the pics are really poor and from awkward angles. Which is why I ended up saying your call.
So if mine I would probably have planted it this deep, so that root might have been useful for the aesthetics of the whole base, after shaving it down a bit. Id also chop low. you didnt post back pics, but i can just about make out another root that looks like it would also be better deeper in the soil.

Ah I see, with collected trees you would want to protect the roots as much as possible, a lot of folk tend to bury deep first then uncover/reveal more later when the plant becomes established. A bit like when you sever a layer for the first time. Your call, you have the plant in front of you and you know how much root is under the soil.OK, I see your point.

Yes, looking back at the precollection photos (post 28), I see that most of those roots were above the soil before the digging it out. That was a factor in not burying them in the grow box as well. If large surface roots like on these two trees are covered with soil and S. moss, is there anything else one can do to promote new root growth from them? Like scarring the bark.Ah I see, with collected trees you would want to protect the roots as much as possible, a lot of folk tend to bury deep first then uncover/reveal more later when the plant becomes established.

Rather than disturbing again, I would maybe top dress with more soil and S moss.
Looks like they were all sitting at soil surface. all of them would have had finer roots attached going into the soil. You have set the tree slightly higher than it was at collection. This will make it a little harder for new roots to regenerate from the roots youve cut. I imagine theres still some roots attached to the big roots underneath, strong growth periods will help to generate new roots from the stubs.Yes, looking back at the precollection photos (post 28), I see that most of those roots were above the soil before the digging it out.

Not only is burying the nebari deeply important to esthetic, but also the health of the collected tree initially. Whenever I dig a bigger tree, I make certain the nebari is at least under two inches of soil in the training container. That's because exposing the root crown in the summer can dry out and kill portions of it. As time passes, and the tree's root system develops and it is repotted, the nebari can be exposed bit by bit. At this point esthetics are the last thing on the list for this collected tree. Health trumps everything else and will for the next couple of years. everything you do to it for 24-36 months should be about keeping it healthy. Don't make design plans, don't implement designs, don't try to reduce leaves or increase ramification. You do those when the tree is healthy and strong after it has recovered completely from collection...Ok but again, looking at it now, I might have just buried the tree deeper.
