So... with all those raised beds, you are still growing potatoes in a trash can?
My Mom always used to accuse me of trying to grow potatoes in my ears, but I think growing them in a trash can is far more worthy of scorn.
Maybe you guys should get some of those upside tomato plants you see on TV all the time. You don't even need soil.
