Joe, I take it that the bark inversion technique is used mostly on seedling trees.  I guess it could also be used on grafted trees to keep them shorter.  I have a Red Clementine seedling with a trunk diameter of approximately 1/4 inch.  Can the bark inversion be done on a trunk that small?  I thinking of doing the inversion to reduce the time of flowering.

Am doing it on my grafted trees as well, same effect, unless the rootstock is ultradwarfing, then very little effect. I have done it small calipers like 1/4" but you'll need the band around it to be smaller also.

I just tried it on a tree with fresh new growth but the bark band started breaking into pieces as I was removing it so I stopped 1/3 of the way through and put the pieces back.  I feel like the bark on my trees is never slipping enough to graft.

When you see new growth the bark is slipping...

I was just going to ask about timing. Do it when bark is slipping?

I did a rose apple, wax jambu, white sapote and key apple last night. Tried Java Plum too, but could not find edge of bark. It was like cutting into a watermelon.

Will keep y'all updated.

It would still have an effect, although mild. The scoring and the 1/3 removal and putting back would be equal to mild girdling technique.

as a novice grafter, I find this extremely interesting.
I have a nice Loquat I want to "try" to maintain at about 6ft tall.

thanks for sharing this !

and - Sylvain thank you for the time you took to make the PDF !!

My experiment was mostly a bust.

Rose apple just made roots, no flowers:

Wax jambo as well.

White sapote only sprouted a new branch below the inversion:


Kei apple actually flowered (out of season), but only a handful:

JoeReal, is the expected dwarfing effect from this reduced vigor or actually shortened node distance? 

Btw my gold nugget failed attempt has recovered just fine with no leaf loss.  I'll try again on another tree at some point.

Howdy all,

Two questions:
Anyone try this on trees grafted to Flying Dragon?
Is there any effect on fruit quality?

OK four questions
Would this be useful on potted trees? (I'm mostly thinking of lemons here.)
Does the width of the removed bark strip have any consequences?

Thanks Steve H.

Interesting. Keep us updated next season. The effect is usually the next season, not almost immediately.

The effect is reduced vigor due to less root growth, not shortened internodes. It should increase fruit quality and size.

I don't think it would help much on Flying Dragon, but it would be good to try. I have a 15 year old Flying Dragon and it's height stayed at 4 ft without any pruning, so I didn't bother to do the inversion.

On semi-standard trees, like citrange trifoliate rootstock, it will improve fruit quality, size and flavor, at least from my trees.
Yes, it is useful on potted trees. I am maintaining apple trees, pear trees, stone fruit trees on pots and I do bark inversion on them. It's a good way to keep them small and their fruits large and tasty.

The larger the width of the band, the larger the effect. If very wide enough, it might kill the tree slowly, and you should do a bridge graft when you see slight symptoms that the tree starting to fail.

Treat this like mild girdling of the tree where the tree is able to heal the girdle around it.

JoeReal, thanks for posting this technique. Great pictures and descriptions on how to perform the operation.

Have you experimented with any other unusual or novel grafts?

I have an in ground Cara Cara grafted on Flying Dragon,  I no longer exactly remember the age of the tree, but it must be around 15 years old.  It is now 11-ft tall and 11-feet wide.

At that age it must give you high quality fruits! less than a foot a year!
