QUESTION: Are coffee grounds green or brown for compost?
ANSWER: This is sort of a trick question! Coffee grounds, though brown in color, are considered a green material for composting. Be sure to add plenty of brown materials to balance out the green materials that you add to your compost.
In composting, a “green” material means that it is nitrogen rich, and a “brown” material means that it is carbon rich. You need both to compost effectively at a decent speed.
