Rather than throwing away leftovers from food in your kitchen, you can use them to grow more. Learn how to turn a single sweet potato into a pot full of them. Grow a salad from the end bit of lettuce and a lemon tree from a single seed. Several of these projects require nothing more than a jar, a windowsill, and a few pieces of food that would otherwise end up in the trash or compost. Step-by-step drawings and photographs make it easy to follow along, and fun recipes will help you enjoy the fruits of your labor.
