Says it can be grown outdoors up to latitude 43 if I remember. Nov. harvest, my location usually gets first frost late Sep. to early Oct.
Yes, square bales for years. I think my cuz bought the round baler around 82 while I was in service. We are still using it, but it's on it's last legs. Getting harder to find parts too.
Yes, we have deer everywhere now. Even if I could hide one somewhere, they would likely damage it, plus cattle is all around me. Neighbors close enough to see the fields. I miss how it was here when I grew up, much quieter, fewer people, and no deer to damage things. They destroy fences in the woods.
