Grow your own fruits and vegetables from nothing but kitchen scraps 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.
