Thanks for the info @Adair M. I'll try putting some more grafts on the top of these branches and cross the scion like you suggested. If there a limit as to how many grafts you can put on a branch? also i used a grafting knife and some attempts I could not make the stock cut long enough.. I think I went too deep too early and hit the wood! your slicing method sounds like it my solve this. Also if the first graft fails can I just try again in the same location bit a little closer to the trunk? I'm not too confident these will take TBH!
