Grow your own?

How much does it really cost to grow your own food? Once you get good at it and have established gardens the costs are pretty low, but for the novice gardener the tools, fertilizers, plant sets and dodads can really add up! Becoming a gardener has many ups and downs, pests invade, rain falls, or doesn't fall, and harvests are gathered. Through it all the author perseveres, and learns, among other things, that itemizing the actual cost of homegrown produce doesn't begin to show its' true value!
