Persimmon grafts. How long?

I did some bark grafting on my persimmon trees about two weeks ago. I had good heathy scions and bark grafted them once the trees had put on new growth. After two weeks still no green buds. The sap was flowing well and the bark piled back easily. How long does it normally take to see bud break after grafting?
Persimmons here in VA are just now starting to coming out. Give it some time.
