I'm assuming your jujube is a Thai Giant, since that's the only variety I've seen for sale in my part of Florida. I don't know anything about other varieties. Those little buds you see will turn into tiny yellow flowers, which may, or may not, become fruit. My largest jujube has been flowering like crazy all summer, but isn't producing any fruit. Last January, this tree produced lots of fruit. What's happening now has me confused. I've never seen a fruit tree absolutely covered with blossoms fail to produce fruit!
If your tree is anything like mine, you'll be surprised at how quickly it will grow. I hope yours has plenty of room!

Mine is a Tigerclaw and it bloomed twice this year with no resulting fruit. It was just planted this spring though and yes they do grow fast.

thanks for the advice....there is room for it to grow up to 20' or so.
