Thank you all for the encouragement! Millet, in my excitement to relay the story, I neglected to mention that I have been experimenting on bark grafts on my apple trees for the past 2 springs. Different media, but practice nonetheless. So I cannot claim such good results on the first try, although I guess that is exactly what I did.
That is where I picked up the idea to prestretch the tape, as I lost a few grafts that seemed to pop right out of the incision after an extremely hardy rain. To me it seemed as though the flow up the tree's cambium layer was too much for the tape to hold the graft in place. I thought that I had used a good tight wrap, but it was not good enough. Prestretching the tape before firmly wrapping allowed the tape to draw tighter, it seemed to me.
The flying dragon stock was quite hard to handle at its size. I probably would not have tried it but for the fact that the branch that I lost on the meyers had a couple of tips that were the same diameter as the rootstock. I justified it because I had quite a few seedlings, and there is no time like the present! I almost cut off one side of the rootstock on one of the grafts because it was so thin, and it was hard to keep in place while I wrapped it. All in all, though, it was a good experience and I am so glad now that I did it.
