Re: Grafting CHestnut or Centennial Crab?
Certainly worth a try, John. I have both grafted, they did not seem at all unusual in their behavior, but they are also not on standard rootstocks. One is grafted to perhaps a granny smith trunk and the other is grafted to a random seedling, FWIW.
I suspect there are clonal rootstocks that have difficult times with certain crabs.
