Are coffee grounds carbon or nitrogen?

Used coffee grounds have about 2% nitrogen. Their C/N, carbon nitrogen ratio, is 20, or about 20 parts carbon to one part nitrogen. While coffee as a drink is acidic, the spent coffee grounds are not. The water leaches out the acidity leaving the grounds a neutral 6.5 to 6.8 pH.

Are leaves green?

What happens if plants have too much nitrogen?

Too much nitrogen causes plants to become spindly with frail stems. As the foliage continues to grow abundantly, the weak stems become less able to support the plant.
