Grafting ST Maui onto Tebow/Young

I decided to graft a scion of ST Maui onto Tebow. I hope it works.

I read on a web page to do this. Its a variation on bark grafting.

I have no clue if I did this right, I tried to line up the cambium.

This photo is a bit blurry.

Tied up…

… and bagged.

Et Voilá.
Update: failed.
