Composting has a reputation for being complicated, something reserved for serious gardeners with a lot of space and even more patience. In reality, composting is one of the simplest habits a household can pick up, and it works in a small apartment courtyard just as well as a sprawling backyard. If you’ve ever wondered what to do with all those vegetable peels and coffee grounds besides tossing them in the trash, composting is the answer, and it’s easier to start than you’d think.
