Since my tree, a Nikita's Gift, is small and does not have many branches. If these 2-3 grafts do not work, I feel that I've wasted not the scionwood but the perfectly good branches of NG.
If I failed again this year on persimmon grafting, I'll leave NG alone next year.
I have a donated persimmon seedling that I will put in ground soon. That will be my guinea pig of grafting next year.
When I grafted, I knew the long cold stretch was coming. I just decided to do it because the leaves were about 1/2" so I thought it's a very good sap flow time. Last year I waited until the leaves were more advanced than this year' but failed 2/3 grafts.
