The “ Coffin “ Grafting Method ?

[edzone9]

Hello Members,

I decided to try this method , I believe it was listed by (Sapote ) .

For those of you who are experienced with this method , does this look correct?
The scion is a pencil thick , and has 2 buds on top .
I made sure the rubber bands didn’t cover any buds .

Thanks Ed
PS it’s a Maha top work project .

Hi, edzone9, I've only tried this once recently, but was successful. Your cut scion looks good, but the cut in the rootstock doesn't look right. The vertical and horizontal lines should be more straight, and the ultimate grave should be deeper. Hopefully others chime in, but those are my observations. Good luck and keep us posted!

[edzone9]

Thank you , so need to square off the cut and go a bit deeper ?
Is there a close up video of this method ?
How deep do you go 1/8” ?

Thanks Ed

Dang it, I don't know the exact depth. Just pressed in with my grafting knife till it felt "right", if that makes sense. I just referenced sapote's images when attempting this. If a video gets made, however, you should make it, owing to your excellence in video production!

If it helps, the point of contact was not green (which is not deep enough). The point of contact in the "grave" was cream colored. It was nuts how perfect it was. So nice and smooth, like buttah.

It’s an interesting method !
Going to experiment with it 👍🏼

I went back in and went a lil deeper and put it back together , I hope u hit the sweet spot , tge tree has lots of successful cleft grafts though 👍🏼

Yes, must go deeper on the rootstock to reach the cambium layer (white). Be careful not to scrape off the wet / slimy cambium layer.

Thanks Jeff , I think I reached the CL👍🏼, let’s see in a few weeks .
Thanks afsin for everyone’s help 🙏

In the ever-evolving world of horticulture, innovative techniques continually emerge to enhance plant propagation and cultivation. One such groundbreaking method that has garnered significant attention in recent years is the "Coffin" grafting method. This unique approach has been hailed as a game-changer in the world of grafting and plant propagation.

I don’t know…the cleft and veneer graft work pretty well for me. 
Posts like these are comforting in that they assure me the bots have not yet reached sentience. It all starts with harmless TFF posts.  Next thing you know, Judgement Day!

I may just be a little confused, but what is the difference between a veneer graft and a "coffin" graft? They seem to be identical to me? Here's the diagram from The Grafter's Handbook for a veneer graft, for those who aren't familiar:

[TropicalFruitHunters]

Similar to how I've been doing my durian grafts.  I take the bark layer off like doing a bud/patch graft and then do an approach graft with the seedling tree.

That looks like a bark graft to me.

[drymifolia]

That looks like a bark graft to me.

I usually think of a bark graft as being when you remove the end of a large branch, or even stump a tree, and insert scions between the bark and wood. Here's an example:



That's from here:

Instead, the coffin method looks like a normal veneer graft to me, as I said above.

[seng]

For me, veneer usually has part of the scion protrudes out from rootstock.

Anywase, I have done this 'coffin' graft before on fig plants.  It worked.  It failed on cherimoya (I think the failure is due more to the timing of the graft.)

If you look carefully, you will observe that what you did is not what Sapote did.  What you did is what experienced grafters would assume he should have done, which is closer to a veneer graft.  What he actually did on the grave part was cut two parallel lines wider than the scion, cut the tops so he could peal the back off.  On wood that is pushing the back will slip right off.
The idea is that it would leave the cambium layer exposed over the entire contact area where the back was removed.  It was then simply getting the scion which was not cut vey deep to touch the cambium layer and you would get your graft.

My assessment of what you did is your scion (coffin) is cut too deep and your root stock (grave) too shallow.  So the coffin is sitting on the grave not lowered into it. It could be a wonderful veneer graft and take just fine but it was not what Sapote was suggesting.

If you have another scion it may be a good experiment to try his grave and coffin method as a comparison.  ... I hate that name.

The method is counter intuitive for many folks who have watched a lot of grafting videos but if you do bud grafting (where you peel the bark back, you will see exactly what he is doing.  For the rest of us, we keep trying to improve on his technique for example the post below was from someone who tried and was partially sucessful and found a way to make it better.

Thanks great explanation!

[edzone9]

Is this a similar technique as the grave digger method except for the little flap left behind , great close up of the depth needed for this graft .

[fliptop]

Yes, per my experience, that's similar in terms of how to make the cuts and remove the bark. Great find! PS I heard back from the person I did the grave-and-coffin grafts for, and two more popped. The ones we are waiting on are still green. This was my first time ever using this technique after having failed a couple times with side veneer. Very grateful for this technique.

In the video the graft is called inlay bark graft.
On your tree the graft is called inlay side graft.

[edzone9]

It’s been exactly 10 days I see the swollen buds I hope it takes !

[Orkine]

I know you are excited to see your raft take, but be patient and don't be messing with it.
Remember, there is almost nothing you can do to improve that graft now, but messing with it, there are a few things, perhaps many, you can do that will not be good for it.
