Gardening for (Almost) Nothing
Whether you have a coffee can full of compost or a thousand acres of farmland to garden, you can grow at least some of your own food for much less than you'd pay for it. In some instances, you can for free.
Get a few plants, a little water and some gardening wisdom (the kind found at the local library or through a search engine on the Internet), and you can frugally grow everything from potatoes and carrots to artichokes and zucchini.
Be careful. It can be kind of scary to walk into a garden center and look at the price of bedding plants! Believe me, that's not a frugal plan. For the price of a few of those plants, it seems to be cheaper (and certainly easier) to just buy a few tomatoes and lettuce at the store.
