This I have not been doing with persimmon and really needs be checked out. I'd almost have to use past experience as a control group. Am still grafting and will try a few. Biggest problem will be remembering to pinch off the nurse limbs new sprouts. 
Persimmon likes to send out new growth. 

Now just thinking out loud:  Growing terminal tips generate an enzyme that is transmitted to the root system enhancing root growth. It is known that there are graft incompatibilities and rejections in chestnuts due to enzymic differences between graft and rootstock.  Is there any chance some tree species recognize it's own enzymes as opposed to that of a different variety grafted to it and direct nutrient flow based on the source direction of it's own enzymes?
