"I often hear economists claim that growing a garden is too expensive, that land costs are prohibitive and that your economic return is very poor. I beg to differ.You have the land around your house. You can grow nothing, or you can grow a great garden. The land cost does not change. You also likely water the land, so watering a productive garden is no more expensive."
