You bring up a good question. Since This last graft was over 2 months old and a head graft. I was a little worried that the diameter of the graft would surpass the diameter of the root stock but as you can see in the picture the graft was a little smaller than the root stock. Perfect. I believe I got it a little off center close to the edge. It seems to be taking so far. It's not shriveling and it's even reddening a bit. I believe that is a good sign.

As you can see the graft on the right has taken perfectly. It's already grown to the point to just cover the entire root stock, and is a healthy green. So far I've only had to cut 1 peresk offset from each side. I waited for both to grow about an inch or so. Then I cut with a razor blade and am rooting them for more peresk.

One of the things I love about Peresk is that you can cut just an inch and root it easilly. So you could create 6 Peresk cuttings from 1 6 inch specimen if you wanted. The weather has been really hot out here so the Peresks I've been rooting have begun to take off. I have about 15 so far and every graft I take. I also get an extra cutting.
