For good reason! Glad to hear it’s working. On a peach tree I cut down one scaffold to redo, and the grafts failed, and the scaffold died. I now have a small branch grafted right above where it’s at. Hoping it will survive and grow into a new scaffold. It’s so small though, I had to strip fruit off the new cultivar the branch is way too small for fruit this year. The new branch comes from one of the two remaining scaffolds, has room to develop into a full scaffold.
