What do you do with your orange peels and corn cobs after you are done eating? Most people throw them in the trash can. But most food leftovers do not have to go into the trash. They are biodegradable, which means that they can be broken down by bacteria into natural materials. People who like to garden often put their fruit and vegetable scraps in a special place known as a compost pile.

A compost pile is a spot outdoors where food waste can break down into compost, which gardeners use. This process takes several months. Once the compost is created, people spread this mixture in their gardens to add nutrients to the soil. The compost in the soil helps new plants grow in the garden.

How do you take care of a compost pile? It needs air, water, and heat. Bacteria and other microorganisms break down the food waste into more basic elements like water and carbon dioxide. This process requires oxygen, so people use a shovel to turn compost regularly and help air reach all parts of the pile. The pile cannot dry out, so it should be covered to keep moisture in. Finally, heat speeds up the process. This means a compost pile should be in the sun for at least part of the day.

Food leftovers are not the only things that turn into compost. You can also add yard waste like grass clippings, dried leaves, and straw. In fact, you should add these things to create a healthy balance in your compost. But do not add any weeds to your compost pile unless you want to grow weeds in your garden! Sometimes seeds are left behind in the compost. This can be a welcome surprise if you find a tomato plant sprouting where you had not planted one. The tomato seed was hiding in the compost, waiting to begin a new life in the garden.
