I think wild blackberries might be native to my region, and raspberries may be to you. I rarely see any wild raspberries here. We do have blueberries though. I have 5 little bushes that I planted about 3 years ago, and this is the first year they have a couple blueberries on them.
I have an acre field behind my house, that used to be a pasture. I usually bushhog it once or twice a year. A couple years ago, the tractor was tore up, so I had to let it grow up. It was then, I noticed wild blackberries growing out there, two great big patches. So now when I bushhog it, I just make squares around those blackberries and leave them growing.
