Turning Kitchen Scraps into Soil
Instead of throwing away apple cores and banana peels, a gardener can turn them into rich, dark soil. This is called composting. It works because tiny living things, along with worms and bugs, eat dead plant material and break it into crumbly food for new plants.
To start a compost pile, you need two kinds of material. The first kind is green material, which is wet and full of nutrients. Fruit and vegetable scraps, coffee grounds, and fresh grass clippings are examples. The second kind is brown material, which is dry and woody. Dead leaves, shredded paper, and small twigs belong here. A good pile has more brown material than green, and the layers should be mixed together.
The pile also needs air and water. Every week or so, an adult can help stir it with a fork so that air gets inside. The pile should feel as damp as a squeezed sponge. If it is too dry, add a little water. If it is too wet and smelly, add more dry leaves.
Leave out meat, fish, and dairy foods. They can attract rats and flies and make the pile smell bad.
After a few months, the bottom of the pile turns into dark compost that smells like a forest floor. Mix it into a garden bed, and the plants will thank you.
