Approach grafting JBP (that needs a repot)
« on: February 21, 2012, 09:10 PM »
I recently brought home a JBP in a nursery container that is a little leggy.  There are suitable branches for approach grafting that would improve the tree much faster than if I waited on it to backbud.  The problem comes in when I look in the container.  Its in need of a repot.

Would it be better to repot now and do the approach grafts next year, or do you think it'd be possible to repot (barerooting up to half the rootball) into akadama, lava, and pumice ...AND do the approach grafts, at (roughly) the same time?

Strong tree? Yes. May take a little longer for the approaches to set, but not a real issue. John

Wayne, Good Luck with your JBP.  I too would love to see the progression of the graft. 

I've seen some pictures of approach grafts that have a big hunky callous surrounding the successful graft.  Is this normal?  And I also wondered about the angle the graft comes off the tree, kinda parallel to the host tree.  Are both of these 'problems' from poor grafting techniques or just the downside to approach grafting?

Bad grafts. Set the "scion" portion into a cleft and not on the surface like many do approaches.

I'm using as a reference the thread japanese-black-pine-approach-graft


and particularly these images:

and

as my guide.

I don't see any "cleft" that's discernible in those images.  Can you point me to a better reference?

Oh, it's simply a matter of not enough cambrium being cut off on both the host tree and the approach graft?  So when you do it, it should be flat after fitting it into the cleft?

Wayne, I see again, an approach graft that's not flush with the trunk.  Seems to me, that'll bulge out over time?  I too would love a better reference.

Wayne, the saw is cutting the "cleft" or "notch" or whatever you want to call it. Lots of folks will make an angled cut, like you use for a side veneer graft using a cut scion, those inevitably lead to a bump.

Ahh.  Good call.  Thanks for making obvious for me what should've been obvious already.

I'm assuming your yes is in response to my question of repotting & approach grafting at the same time.  The soil this one's in doesn't drain well and likely consists of lots of pine bark that's broken down already w/ some haydite and/or potting-soil-like mix.  It isn't particularly strong ...as you'd probably imagine from the description of the mix.

I'll try to get pictures of everything before I start any work, ...but it likely won't happen this weekend, or at least not 'til late Sunday.

Thanks for the help.
