Title: Thread-grafting JBP?
Post by: bwaynef on January 10, 2012, 10:23 AM
In a recent search for some JBP info, I came across this post.  It looks like its from an Australian bonsai practitioner ...so if any of our Aussie friends recognize it, get him to update the post ...or point him here.

Basically, he takes a seedling, strips it of all its needles/buds, and does a more traditional thread-graft using the soon-to-elongate candle as the "scion".  I'd suspect that removing ALL of the needles & buds might've set him back more than necessary.  Seems he could've removed just the ones that'd be necessary to push it through the trunk.

Does anyone have any similar experience?  Predictions?  Refinements?

looking at the photos i dont see any options other than taking all but the center candle.

I guess I didn't study the "making of" photos all that well to see that there weren't any lower needles that were removed.

Seems like if we were to purpose grow a scion for this, it might be wise to not remove the needles below where the scion would be inserted into the tree. 

Does that make sense?

Does anyone have a seedling they are willing to sacrifice to see if removing all but the center bud would survive?  It doesn't have to be used as a graft.  It it survives, then I would say it could be a viable thread graft technique.

i think it would make sense to have a back up plan otherwise im pretty confident that as long as its healthy it will survive no problem. Its just a matter of seeing if the two will ever fuse together

I tried this couple of er..decades ago, and found that the small one did elongate and swell but never attached due to expanding dieback of the outbound hole's cambium. 

Have done a multitude of approach grafts , almost always successful


Never hurts to try

Dave do you have an howto guides / other info on doing a approach graft on a JBP?
I have a small Shohin sized one that has a bare patch thn needs a branch, but will not throw a back where i need it. have been looking at a thread graft just like this one ( have heard about doing them as shown here), but if approach will be better then I will go that route.

I am growing a long branch to use a the donor graft material.

Should I wait till the second year growth on the donor branch or this years?
