I brought 2 Indian Jujubes from a private collector this year and they are fruiting right now.
From what I were told, Indian Jujube fruit is remain green, sweet, crunchy and crispy. The size is like an egg or bigger if fertilizer right. Required heavy pruning after harvest the fruits which around April because flowers come from new branches. Flowers season around Oct.
It is very hard to Air-Layer, best graft on a rootstock.
Here is a pic of my fruits as today. They are in a 7 gal now.
