Grafting Question - will this work?

Is there such a thing as a "girdle-bud graft". 


Scion Bud-
From a growing fig stem, girdle off about an inch of bark with an actively growing bud.



Stock Branch:

Girdle one inch of bark off the receiving branch with same caliber and replace with the donor bark binding it tightly.


Should this work? Is there such a grafting technique?  

The problem I see is that there would be zero to no cambium left on the receiving branch.

What am I missing here?


I have never done that, but I have done a patch bud, where you don't girdle the whole receiving branch, but only a square from it. The bark really needs to be in slip mode, and to remove a full girdle of the of the desired patch in good shape might be tough.  The cambium contact on that would have to be on the bottom union, on the patch you have the sides and top as well. Not sure why  not just lop the top of that off as you would not even want the top anymore. Above any type of graft sometimes it is good to half break above the graft/bud and bending it down leaving some of the bark intact for a period until established so the stock should give energies to the graft. I never have real good results with the patch bud but that was years ago and on pecan trees, and nut trees are hard.

Thanks Phil,
So whether you do a patch graft or a girdle graft, the cambium contact would be minimal, ie only along the sides. That's not a recipe for success.
Back to the drawing board.

This is essentially a bridge graft, of sorts, which is used to replace missing bark (chewed off by an animal, etc.) If done properly, it should work, but I see no reason to do it that way. You risk loosing the top portion of the tree if the graft is not successful.

Better to use T-bud or chip-bud. Or a patch bud, see http://anrcatalog.ucdavis.edu/pdf/8115.pdf

I guess I missed the point that you might want to keep the portion of the tree above the girdle. but with that girdle you are actually depending on 2 unions Top and bottom for the top to survive and you don't need to risk losing the top with the patch bud or the T or Chip buds. I am not talking specific  to figs, but in general I have had better luck with either the Chip or T buds, than a patch bud. I really don't see any advantage of total girdle.

Ok, thanks. One more question...
please explain how a T-bud makes cambium to cambium contact. It seems  that the cambium of the T-bud sits atop the denuded stock wood. The stock wood cambium would make up the inner part of the flap and would therefore sit on top of the inserted T-bud. Correct?







the Bud graft works great for me. but the receiving trunk needs to be strong and the surfice almost flat, so the new one (that is flat) has more contact.  I tried the first one you posted, easy to remove and discard the bark, but try to prepare a new one to bring into that space! It cracks and splits, it  was impossible for me, so I gave up.  Maybe soaking prior to do the cuts on the grafting would work, but I have not tried. Like Harvey says..only is a failure if you don't try.


I like this way better:

The flaps do not have cambium, it suppose to be just bark. The cambium is under inserted bud, on the trunk. As Jon mentioned, during active growth the bark separates without the cambium.

Thanks for everyone's input.

The only time I've seen a photo of that ring bark graft done was when someone put back the very same bark back onto the same tree but upside down to create some dwarfing.  I've never tried it myself.

I have a special Tina grafting knife purchased on eBay about 10 years ago with two fixed blades about an inch apart from one another (and parallel).  I believe this model is primarily for patch grafting on walnuts but it would probably be handy for this ring bark grafting as well.

Eureka! I finally found it. This is what I was trying say in the first post.




Fig. 20. Ring or Annular Budding. 1. Stock prepared for bud. 2. Bud. 3. Bud in place and tied.  

Annular Budding.—A ring of bark about one inch in length is removed from the stock. A bud stick of the same size is selected, and from it a similar ring with a good bud on it is removed by cutting around the bud stick and slitting down the back or side opposite the bud. This bud is then placed in position on the stock. After the buds are in place, a piece of stiff wrapping paper should be tied around the stock just above the bud and allowed to flare out over the bud to protect it from the sun and wind. Preferably all buds should be inserted on the north side.Stocks from three-eighths to three-quarters of an inch may be worked by this method.

Therefore in order for this type of graft to take, there would have to be cambium layers located as per drawing below.
