Stone's Throw Farm is transforming the Twin Cities' urban landscape, one empty lot at a time. Using organic practices, Stone's Throw grows over 50 varieties of heirloom and hybrid vegetables, dozens of herbs, and an assortment of flowers. Since 2011 they've converted 14 vacant lots in south Minneapolis, Frogtown, and the North End neighborhood of St. Paul into productive mini-farms. Their mission is no small feat: to make urban farming economically viable, while engaging community members and improving the ecological health of the land they farm. They offer CSA subscriptions and sell to a number of excellent local restaurants, as well as directly to consumers. Yet the challenges they face are formidable. Even the most productive urban farm could never produce enough food to feed the entire city it serves. But helping us urbanites understand where our food comes from? That's invaluable.
