Here's what the two apple treelings look like after summer of a little growth - they grew a little crooked haha. If I wanted to make these multi-grafted, where would you all recommend I do so? Original grafts are basic cleft, hopefully easy to see in the pictures, if not, I can add marks where they occred. I don't know if I have skills to do anything else.
These are m27 dwarf rootstock. I know it's not the most ideal rootstock, but, I wanted to try something small for containers
