Yeah, not planning on keeping them all on the tree long-term, it kinda just happened. I ran out of seedlings to graft to and started grafting extras onto the Ataulfo I was top-working. Everything took when I grafted to the tree, it's amazing how much easier it is to graft to a vigorous tree versus a seedling. Using it as a stationing location for now; next season I'll take scions from the varieties on the tree and graft to a few dozen seedlings I started last season, then I'll assess what I want to leave on the tree. I can already tell Sweet tart would take everything over in short order, it's doubling/tripling the growth of most the rest.
