Pomegranates from gardeningblog.net
You never know what conversations will come up when you talk gardening. I just got new glasses and in the process of coming in a few times to get checked, then fittings, I usually talked. (I can see my wife's eyes rolling right now) I always find something to talk about. :-)
As you expect, gardening is one of my favorite topics and when I went back in yesterday for what we all hope is a final fitting my new gardening conversationalist mentioned that she talked to a local couple who grow pomegranates here in Middle Tennessee.
It never dawned on me that pomegranates could be grown here so I did some research and we are right on the edge of their zone. The more I read, the more I compared then to growing figs, but they have lower water requirements to produce.
Since we are on the edge of their climate range, some of us will succeed and some may failed based on our micro-climates but it sounds like an interesting challenge, One consideration though, they take 4-5 years to make meaningful fruit. So patience grasshopper.
