My 4yo son and I enjoy the book Two Little Gardeners* about a brother and sister who prepare ground, grow food, eat some and store the rest. They preserve/pickle a variety of things in jars, store pumpkins and potatoes, hang onions and garlic, and keep their carrots in a tub of slightly dampened sand (a technique I hadn't heard of previously). It's a great little book if you have children, they're interested in gardening as mine are, and you want to introduce them to the stages involved in the whole process.
