Any tips on grafting Indian Jujube (Z. mauritiana)?

[pineislander]

I'm planning to graft a seedling Indian jujube with the thornless "Thai Giant" variety.
Can anyone offer a tip or tricks?
What season is best?
What to look for in the scion?
What type of graft to make?

Note, this is not about the Chinese Jujube (Ziziphus jujuba)
this is Indian Jujube (Z. mauritiana)

No specific tips, but I have a tree nearby with plenty of material if you need to figure it out by trial and error. I have seen the other species propagated by chip budding.

I recently did my first graft of this type with a whip and tongue graft in March and this is what it looks like today.  The rootstock was already pushing, but the scion was dormant with evident buds.  I don't think I'm out of the woods yet, but it looks promising.   Good luck.
