@clarkinks thanks for starting this thread and keeping it going. The possible chance to graft later into the summer would be great. I have never tried grafting much past mid June. It seems to make sense with what your’e saying about the wax melting and running into the graft area and preventing callous formation.
I just did 9 mulberry grafts, all of them were with fresh cut, this years growth, scions. The cuttings were starting to harden up some, I tried to avoid the very tender ends of the twigs. I used 2-3 year old seedlings for the rootstock.
For each scion I left only 1 bud, all the leaves were removed, then I completely wrapped it with Parafilm-M.
The grafts were all Whip and Tongue grafts. I first wrapped the joint tightly with a rubberband, followed by Parafilm, then a layer of masking tape, then lightly wrapped the whole scion and joint with alum. foil.
Later this week I plan on doing some more grafts, but using a green, this years seedling as the rootstock.
