Jujube graft, how long would it take to heal in general?

Grafted GA866 and Lang to my 4 year old Li and Sugarcane plant last week.
Used cleft and bug grafting.
Typically how long would it take for the graft to heal in Jujube?


I heard something like bud grafting did not work on jujubes. You would have to use a branch at least 1 inch long with a bud. Maybe someone with experiences can confirm if the statement is true?
