The most recent Hort Science has an article “Jujube, an Alternative Fruit
crop for the Southwestern US”. The author is from New Mexico State. Evidently
they are trialing over 50 cultivars at the Sustainable Ag Science Center in
Alcalde. It is at least 5700 ft elevation. They referenced a hardiness to
-30C or -22F.
The authors name is Shengrui Yao.
Also, Gordon Tooley of Tooleys trees may have some insight into hardiness in
NM.

Has anyone successfully grown jujube in zone 5 or colder?
I'm in NM at 7000 feet. There are a number of trees that I've tried here that
ought to grow in even colder climates but which get their tops killed in the
winter. I think it's a combination of temperature (record lows have been
-25), wind, strong sun, dryness, thaw and freeze. The trees that have
topped-killed include Illinois Everbearing mulberry, American persimmon, and
walnuts. The American persimmons eventually get tough enough growth to
survive, but any grafted plants lose the grafted portion.
I'm concerned that the tops of jujubes would not make it. Any experience?

Jay
