Skin Graft

[penumbra]

But the healthy callus that formed is just what healthy plants do. Unless the graft takes I don't see that it had any effect on the callus formation. Don't get me wrong, I applaud your efforts and wish you some sucess in your skin grafts taking, it is simply that it has not yet proved itself a reliable method. I hope it does work out for you at some point, and though it seems like a lot of work to me, somebody has to keep pushing the envelope. I will be continuing to watch your follow ups and hoping for the best.

Thank you very much for your response.
Yes, I know about callus formed in healthy plants, but what I like it here is that callus growth is much faster than if I don't put the graft on. In my area, the pine's cut wounds can take years to heal up completely or they never heal. So, even though my success rate of skin graft is 50 % so far, I still really like what I got. In failed cases, I think I know what the reason. This season, I have been grafting quite a bit. Hopefully next year, I can see success rate can be increased

That sure is a game changer. That's fabulous.

This KBP had skin graft in 2 places on 6/14/2021. I did a Fall work on it this afternoon. After.





2 grafts still had grafting tapes on


Grafting tapes were removed


Both of skin graft heal well!

This piece of skin fell off in one month after tape removal.
The wound surface is healing very well at this time.

Today, the healing process of this cut is almost the same !

Is the conclusion that the skin graft does nto make a difference in the ultimate healing?

Is the conclusion that the skin graft does nto make a difference in the ultimate healing?

I think the conclusion here is that in the first year (with graft in place) a lot of callus was produced, whereas between graft removal (or failure) and now, the wound appears to look more or less the same?
My question would be, how much of that can be attributed to the compression on the area, from the tape and skin piece, rather than the actual ‘graft’ itself?

Most of this seems inconclusive. A side by side type experiment could be telling. Create two similar wounds on similar but separate branches on the same tree and treat one with the “skin graft” technique (not a fan of that term ) and the other with traditional cut paste. It just seems hard to make a real world comparison on all these different wounds with different outcomes without a control to compare it to. I think the work is worth doing if you want to put your name to this technique and see it used in the hobby (lifestyle).

I know this would be even harder to accomplish, but, I wonder if it would be possible to leave the "skin" attached for higher success. Actually cutting the branch off while keeping the bark attached by a tab would be pretty difficult.

Isn’t there a technique that Ebihara uses that is exactly this or very close?

Wouldn't put it past him, but it's one I haven't seen!

check the van Meer technique.
I THINK this is also in bonsai techniques book

Hi Leatherback, CptnGlyn answered your question. Skin graft helped the healing process quite a bit even when it failed. It means if we can use anything to cover the wound such as cut paste, tape, vaseline, it should help the healing.

My question would be, how much of that can be attributed to the compression on the area, from the tape and skin piece, rather than the actual ‘graft’ itself?

As far as I know, skin graft with the punctured tape compression is better than the one without the tape.

Thanks for suggestion. Yes, I know I should have made standard samples for scientific comparison, but because I just thought about this technique last year, and I wanted to try it as a trial. If it works well, then I will compare it with other technique. So far, I really like it. Because of that, next year, I will experiment it on my Huangshan pine seedlings which I am having a lot. Hopefully I can have at least 30 samples.

I know this one and tried once in the past. It was very consuming time and did not work well for me.
