"Some kids have never seen what a real tomato looks like off the vine. They don't know where a cucumber comes from. And that really affects the way they view food. So a garden helps them really get their hands dirty, literally, and understand the whole process of where their food comes from. And I wanted them to see just how challenging and rewarding it is to grow your own food, so that they would better understand what our farmers are doing every single day across this country and have an appreciation for ... that American tradition of growing our own food and feeding ourselves."
