About 3 or 4 years ago, I bought and planted some blackberry bushes but they haven't produced a thing. How long does it take before they start blooming and bare fruit? I don't know what zone I am in. I live in Wisconsin. In Oregon, they grow huge wild one's, but because I couldn't find wild ones here, I decided to pant my own. I had also tried planting raspberries and blueberries, but they died. I later learned that blueberries prefer acid soil and I don't know what I would need to make the soil acidy. moderator's note: added a more descriptive title to topic
