My lottie has ten raised beds in two rows of five. This gives a good rotation, the first crop not coming back to its first position for six years. Hungry crops like beans and cougettes need lots of humas to hold water in raised beds, but like PAULW says it depends of the soil. On mine raised beds work but as mentioned above, some crops would need help in keeping water there as raised beds help drainage.
