Coffee grounds may be brown in colour but, like tea leaves, they are actually nitrogen-rich ‘green’ material. Coffee grounds also add magnesium and potassium to your compost. While you can toss coffee grounds straight into your garden, they are an excellent addition to your compost. If you use a coffee filter, you can toss it into your YOLO Compost Tumbler too (tear it into small pieces first).
