Grafting apple trees

Asked July 25, 2017, 9:39 PM EDT

I grafted a scion onto an existing apple tree. I didn't follow any of the proper rules. One graft took. Now I don't know what to do next. Here are the details. I moved to Minnesota from Idaho. I had an apple tree in Idaho that had the best apples, so I wanted a tree of them here. ( I have no idea what kind of apple they are) I moved to a house in Pine County that had a small apple tree (some type of crab apple considering the size of the current apples) that is maybe 10 feet tall with a trunk diameter of about 1-1/2" to 2". All of the bark is still green. It's a young tree. I gathered the scions in Idaho in June of last year, stuck them in the fridge for about 1 month, then grafted them in the middle of July using a side graft at about 24" from the ground. I didn't cut anything off of the original rootstock tree. I totally thought it didn't work, but very late this spring, the scion finally has a few leaves. It has not grown at all I know that I'm supposed to cut off the rootstock above the graft, but am totally afraid I'll loose my one living graft and don't know if I've created a situation where I won't be able to cut off the the original rootstock tree. The goal is for this tree to be ALL Idaho apple. What is my next step?

Here is information from the University of Minnesota on grafting and budding fruit trees:

Lastly, this publication from Iowa State University is also a good one.
I hope these three publications help!
