Compost is a dark, crumbly mixture made from decomposed organic materials like food scraps, leaves, and grass clippings. When you toss apple cores, banana peels, and vegetable trimmings into a compost bin instead of the trash, microorganisms and worms break them down into nutrient-rich material that helps plants grow stronger and healthier.

Composting turns waste into something valuable. A compost pile or bin needs the right balance of “greens” (like fresh vegetable scraps) and “browns” (like dry leaves or cardboard) plus air and moisture. Over weeks or months, everything breaks down naturally into a substance that looks and smells like rich earth. Gardeners love mixing compost into their soil because it feeds plants and helps the soil hold water better.

Many families keep a small container on their kitchen counter for compostable scraps, then dump it into a larger outdoor bin. Some cities even collect compost from homes the same way they collect recycling. When you compost, you're doing what nature does in forests, where fallen leaves and plants decay and create new soil. It's a simple cycle: yesterday's lunch becomes tomorrow's tomatoes.
