Re: [nafex] jujube in "cold" climates

I'm in zone 5 (northern Utah/Idaho border, 4,900' elevation, 18" annual precip) and grow Li and Lang, now nearly 10 yrs old. They are planted on a south-facing slope, slightly warmer microclimate, very hot/dry summer location, high winter wind area. I get good crops and have not experienced winter injury. I watered them first 2 yrs to get them established, but they have no supplemental irrigation at this point, though are in a bed with deep mulch (permaculture system) and companion plantings w/sea buckthorn (N-fixer). Lang is 8' tall, Li stopped at 4'.

I'm in zone 6 and I've been growing jujube for years. I don't think they'll
do good in colder zones, specially areas with short seasons.

Yes, short seasons are the issue.

I am in zone 7 and had a short list of varieties that would bear early
enough in the season. I grow So, Sherwood and Shanxi Li.

They bloom late, so late frosts are not an issue.
