Jujube seedling cold tolerance

[growinginphoenix]

Jujube are supposed to be hardy to zone 6 I think. I have a jujube (Chinese) seedling that is maybe 4 inches tall. I'm in zone 9b. It can potentially get down to 20F over night in my yard. Will this little seedling take that kind of cold if I plant it out in my yard now? Or should I keep it in a pot and protect it this winter and plant it in the spring?

I was considering the same thing. I have two small tissue cultured jujube in pots. I think they are supposed to be able to take the cold, but I am planning to wait until spring to play it safe.

If the stem is wood (lignified) it will be fine but at that size I wouldn't risk something happening to it animals, slugs, etc. So you will need to protect it. I've had woodchucks and deer chew up baby plants to the base of the stem, leaving no buds to sprout from
