I have a very small backyard. I want to plant a bi-color hybrid dwarf corn. My raised bed is only 3ftx2ftx8in. I want to know that because it's so small am I wasting my time here. Thanks Garydavid.
Garydavid: Your raised bed is very different from a container, so you're unlikely to get useful tips here. You might find answers to your questions in the Squarefoot Gardening Forum or the Vegetable Forum.
