About this course
Learn to turn kitchen scraps and yard waste into dark, crumbly compost by mastering the four levers that decide success: carbon-to-nitrogen ratio, moisture, oxygen, and particle size. You will mix browns and greens to a roughly 25 to 30 to 1 ratio, build a hot pile that hits 55 to 65 degrees Celsius, run a low-effort cold pile, diagnose a stinking or slow heap in minutes, and set up a worm bin indoors. By the end you can build, feed, turn, troubleshoot, and harvest compost, and apply it to beds, containers, and lawns without burning your plants.
