We have a good size garden, but because we live in a short growing climate, we decided to try to maximize our yields. We do square foot gardening on a larger scale and it's incredible the amount of produce we get. We aren't using raised beds as instructed in the book. We have just mounded up the beds. Make sure that you add compost to your beds every year.
It's very easy and you will also have to weed less often. A real bonus.
