Grow your own food -- in a bag, in a truck, anywhere
Gardening isn't just for people with lots of land. You can raise your own tasty crops in the smallest and oddest of containers. If you have access to some sun, plus time to water and care for seedlings, every little spot in the world is your garden.
About.com has tips for growing a head of lettuce in a Whole Foods reusable grocery bag. Typically, these bags are reused when you buy salad fixings at the store, but why not use them to raise fresh salad at home? Doesn't look that hard.
In fact, an entire Flickr group is devoted to Grow Bag Gardening. People around the country are growing potatoes in potato sacks, fertilizing plants in bags of fertilizer, and even raising crops in tin cans.
The container gardening site at Texas A&M also suggests using a cake pan as the site to grow green onions, radishes, or beets. What a great way to use an old pan that's scratched or warped or to use something found at the thrift store.
