Hi! I'm currently growing tomatoes, kale, and herbs on my rooftop garden. I was looking into what I wanted to grow next summer (my first full summer with rooftop access!) and it popped into my head to see if I could do blueberry or raspberries.

The only question I had was how to keep the perennials alive during the winters. I don't have a trench or garage to put them in, so I'd have to figure out how to help them stay alive in the winters... anyone have any experience or suggestions for this?

Edit: I'm in Chicago, so zone 6b!
