10 clever uses for coffee grounds
Fertilize your garden
Coffee grounds are rich in nitrogen and potassium, key minerals for plant growth, plus many other important nutrients that can help replenish the soil. Used grounds also attract earthworms, which boost soil health. To neutralize coffee’s acid, which can hinder certain plants, and create a more complete fertilizer, pair the grounds with carbon- and phosphorus-rich materials such as dead grass clippings or wood ash. Then just scatter your fertilizer around your plants and watch ’em grow.
