One of the things I experimented with is the grafting of some tree and itoh peonies and I'm finding that there has clearly been bud swelling from these grafted plants which is a clear indication that the grafts have taken. I have taken them from scions and nurse roots of all sizes ranging from the 1/4 inch diameter stuff to 3 inch diameter/ 5lb nurse roots attached to a whole tree peony branch. The purpose of this is to see the results and learn from them so I can develop an understanding of the true requirements of getting successful grafts.
Here's one of the massive ones where I take the biggest herbaceous nurse roots I can find, and hook it up with a nice big branch and these seem to be taking very well as expected. The buds are fattening up on the scion meaning that energy from the nurse root is already getting pumped in there.
