Couple more pics

I do not see a graft scar. You can graft it in Spring.

I grafted, both trees. To each other and from a hass.

blow up pics. I should have started with this.

i doubt they have been grafted, however they look so much like grafts.

My young avocados from four winds have some very obvious callus from grafting. So in my limited avocado experience I would guess that most if not all of them callus heavily.

Only an educated guess.
