Just wonder what are the five jujubes you grafted if you don’t mind.
I've just created a mutigrafted jujube this spring. It has sugar cane, honey jar, chio, shanxi li, ga-866.
My honey jar has the most fruits, but as oppose to people's oppinion, my honey jar fruit is extremely small and tatse like wild jujube, has less flesh as well as big seed, not extremely sweet. I bought mine from justfruitandexotics, and I guess it is not true honey jar jujube.
I grafted 2 scionwood pieces of Chico on an old wild jujube and both took, but I removed one because it was cover by other branches and lack of sunlight. The other grafted Chico branch has the most fruits and most of them held. Chico fruit shape is similar to an apple, and not ripe yet till this moment.
I think multigraft will help to i prove the taste of jujube. I also noticed that my Sugar Cane has bigger fruit.
