Learn About Composting Day, observed annually on May 29, encourages everyone to learn how organic waste can be turned into useful compost. Composting recycles materials such as kitchen vegetable scraps, yard vegetation, paper, untreated wood, and cardboard into a rich soil amendment. It can help reduce food waste and improve soil health, making it a practical activity for gardeners and non-gardeners alike. Composting can also lessen the amount of organic waste sent to landfills.
Bob Matthews of Rochester, New York, created the holiday in 2011. His interest in gardening and desire to help the environment inspired a day focused on making composting more accessible. Whether it becomes part of a garden or is shared with someone who has one, compost gives discarded plant matter another useful purpose.
How to Observe Learn About Composting Day
Celebrate by learning about composting and the different ways to do it, including compost piles, tumblers, and bins.

You can also share what you learn with family, friends, a school, or a local gardening group.
