I have been wondering about this as well. I have never grafted a tree yet, but I do have some supplies, (grafting knife, tape, etc) and have been trying to learn on the internet. I have tons of hickory on my farm but no pecan as far as I know. I would like to have some pecan. Maybe this would be a good way to get my feet wet and not ruin some of the native male persimmon that I had planned on grafting.
