Thanks all for the comments, and I will take the consensus advice and wait a while to let (or should I say hope) the graft flush out before doing anything. It still has a way to go, but so far so good.
It felt good to be grafting again, it had been so long, I was afraid I had forgotten how to do it. I also did three cherry trees and most of those grafts appear to have taken as well. So if all goes well, later this spring/summer I will a coconut cream mango as well as two Royal Lee/Minnie Royal cherry trees available free to good homes in the Southern California area
