Welcome Micah! I have a small city yard and grow potatoes in the black nursery containers that trees come in. I admit they don't produce tons but they are mainly for my preschoolers to see where potatoes come from. They are easy to grow and harvest. The kids love digging gently in them to look for the treasure. I mulch mine with rice straw. I've never had a problem with watering or draining since they have holes at the bottom. I used to think that the black plastic would "cook" the roots but that doesn't happen. Could be that our weather is on the cool side.
