Grafting based on calus, instead of cambium?
« on: March 11, 2023, 02:24:18 PM »
Some plants are tough to graft. Guava is one of them. Currently, approached grafting seems to be the most successful; however, it is tough and time comsuming to setup.

So I'm thinking what if we graft by calus instead of cambium? Note that I have not tried them out yet.  Let me know what you think.  Here are the steps.

1-cause wound on both scion and rootstock by peeling off a strip of bark. Note: do not cut off scion or top work the rootstock.

2-Let the scion and rootstock try to heal the wound by forming calus at the edge of the wound.

3-Once there is enough calus formed on the scion and rootstock, do these:
a- remove the scion by cutting off below the wound. Wrap it with parafilm.
b- top work the rootstock by cutting off above the wound.
c- gently scrap (not remove) the calus on both the scion and rootstock.
d- attach the scion and rootstock, making sure their calus are contacting.
e- wrap the joint.
f- Shade the scion with a piece of leave, paper, or aluminum foil.

sounds interesting, how long does it take for the calus to form enough to try the graft?

It might work but the graft union will probably come out fat and ugly. I hope it would heal like a normal graft.

I would be interested in hearing and seeing photos of your results.

I will try this approach this year.  Will update the result afterward.

One aspect of grafting is the physical " carpentry" type cuts and joins between rootstock and scion to give strong connections. Fruit trees have to hold loads of fruit and stand wind movement. Any thoughts on how the cuts you make will ultimately interconnect the rootstock and scion.

You bring up good point.  For now, I will be focusing on whether it works.  The joint will be simular to "approached" graft, so it will have simular strength.
