Bruce,
I live in East TN, right next to the Smokey Mountains. I definitely grow for the food. Last summer I was just going to grow 2 tomaotes in pots and some squash in a small flower bed. Then...the gas prices went straight up and the cost of groceries went with them. I decided that I can grow the foods I really like and that are expensive. My great husband supported me in my venture, although he is NOT a gardener. I had a local farmer till a garden 30x30. I figure kids are a great source of a work supply

I had my 4 yr old out picking beans and ripe tomatoes. My 12yr old weeded and picked. EVERYBODY broke beans! My garden produced 12doz ears of corn, more than 3 bushels of green beans and more than 3 bushels of tomatoes, a dozen green and red peppers, and sweet potatoes (a huge amt.) I have quit the fast food track and giving quite so much to the stores.
I also planted 3 cherry trees, a plum, and a peach. I already have 6 blueberries that produced more than 10 gal. This winter I've planted 2 apple trees and will plant 2 more this spring. I want to plant 2 or3 grape vines and a strawberry bed. I am trying to decrease my dependence on the retailer.
Sorry for the long story. I don't know how to keep it short.
