    A jin and shari exercise

    Like so many of my projects, this one started with a dumpster full of juniper branches I have had this tree for years, but excess foilage was giving an illusion of a nice tree, when there were fundamental issues with it. As soon as I repotted and trimmed aggressively, I saw a tree that needed a LOT of work.



    Unfortunately, I did not take any "before" photos (before I trimmed) so that people could have seen what it looked like. What it looked like after the trimming was a boring juniper with a great nebari and little else. There was an especially bad section in the middle of the trunk where there was no taper and the tree was missing a back branch. I decided to build on the strength of the tree - the nebari - by adding an interesting shari and a couple of jins.



    Here I was starting on the long jin to the left, and I discovered a section of rotted wood. When you run into this on a tree, it is best to remove it all (if you can). I was to find several other pockets of rotted wood on this tree - old sections of shari that I didn't know were there.



    Here is a big chunk of particularly ugly wood that looks like an alligator head. I wanted to reduce this dramatically, but wanted to get below the bark first so I could make the break look natural.



    Here I am carving a deliniating line between the two jins and where I wanted the shari to end. I find it easiest if I carefully carve the shari borders first, then clean out the interior afterwards.



    I didn't want the shari to extend too far up the trunk... yet. You can always make a shari larger, but you can't make it smaller. Future plans include a possible trunk chop or airlayer, so I wanted more live bark on the middle of the trunk to keep my options open.

    Here is my alligator friend! Talk about an ugly jin! I had to remove the "eye" and cut the chunk back - but it was important to make it look as natural as possible.



    Examining the branch, there was a vein of live wood along the top with a dead hollow beneath. I knew if I broke the branch at the hollow, the upper part would project farther (because the live wood was stronger) and I could reduce the hollow further to make it look like a hollow branch.



    I think it turned out nicely.



    The ends of the left jin needed to be finished. So I crushed them with a set of heavy pliers.



    A little peeling and carving and I ended with more natural ends. I may reduce this jin further depending upon the future design of the tree. But for now I left a longer jin for fun

    Here is how the jins & shari turned out. Front view.



    Top view.



    Back view. Note how the freshly stripped live wood contrasts sharply with deadwood that existed prior (that you couldn't see because it was beneath old bark). I carve all my jins and shari by hand without power tools. I think you can tell the difference (though if I had a BIG tree I would probably have to use power tools simply because of the time required). I will be applying lime sulfur after the wood dries a bit. I typically apply several dilute coats over a number of weeks (I will post photos of the results in a bit).



    So here is the "after" shot. The tree looks marginally better, but needs a ton of work.



    My future plans involve a graft in the middle of the trunk this Spring. There is always a chance that I might pop some buds there given the dramatic pruning. Once I get some growth I will let the tree rest for a year or so, then probably air-layer off the top.



    P.S. Branch angles are NOT final in this virtual. Certainly the lowest branch on the left needs to come way down.

    Very informative photo essay. What tools did you use to carve the jins? Creating jins is one of those things that seems easy in theory but is quite challenging in reality.

    One of my bonsai resolutions for the new year is to become more accomplished in creating jins. This article was a great way to start.

    Thank you.

    Thanks for the pictorial BN. The finished jin, from the front now looks a bit like an elephant head and trunk.... But a definite improvement on the aligator.

    That first 90 turn in the trunk is a bit of an issue, isn't it? Have you considered replanting as a cascade?

    I use X-acto knives and very sharp hand chisels. Also, at the very end you can use a dremel with a wire brush to clean everything up - the wire brush isn't strong enough to harm the wood, but it will remove any remnants of leftover bark.

    Everything about this tree is an issue I almost hesitated posting anything about it because I have not figured out how to bring out the best final bonsai. I didn't think it was that bad until I cut back the foilage I considered a cascade due to the first bend, but I don't really gain anything because I will still have to fix that long section of trunk. Plus, a jin would bury much of the nebari, which you can't really see in my photos but is really nice.

    So I think I need to get a lot of back budding or else try grafts. Once I get some branches down below, I think I will try an airlayer. Here is a quick virtual. Cut in half you end up with two decent trees:



    I am not happy with the final look of the jins yet. I think they both need to be reduced more. However sometimes when I am busy with the work of jinning, it is hard to step back and develop a clear vision of the final result. So I leave my jins long to start, rest a few days and look at the tree for a while (or do virtuals on the computer) and develop the final plan. The "stump" jin will probably lose the bottom half, even if I don't shorten it. It is still much too heavy visually.

    Bonsai #2 would make a nice semi-cascade. A slight tilt to the right and just grow out the primary branch.

    Here's a quick shot of the base from a slightly different angle. The 90 degree turn is not as bad as it looks in my other photos (otherwise the tree would have been heading for the compost by now)

    Hi BN,
    Nice job!! What I would do now before the wood drys out is to take needle nose pliars if you do not have a jin pliars and pinch into the heavey part of the jins to get the wood strands and peel it like a piece of meat. It is still green and it should peel off in strands giving it a more natural look. While the wood is still green your strands will be longer. When the wood drys out it will be much harder to pull off strands and and if you can they will break off much shorter. Am I making any since?
    This gives the jins a much more natural look and not so much smooth.
    Just a thought.

    This is what I was talking about Greg. See how pulling the strands of wood gives it a much more natural feeling?
