Most of us have a can or 12 of Campbell's soup in our pantry. Now, if you have an aspiring green thumb, you can find a way to make it work for you.
Visit HelpGrowYourSoup.com to request a free tomato seed packet. You will need one can of Campbell's Condensed Soup to do this - but there's a catch. You'll need one that has a 5 alpha-numeric + 2 alpha-numeric code on the bottom of the can. (The two cans I'd bought yesterday at the store didn't have that, so you'll have to check yours.)
Even if you don't have cans on hand, you can still help donate seeds to FFA chapters. Just fill out your seed packet request form to donate 100 seeds and then click on the "Grow" button to donate 50 more seeds. You can click again tomorrow to donate another 50 seeds.
