Want to reduce your carbon footprint? Wondering if there’s a better use for your used grounds? Try adding them to the soil.
Fresh coffee grounds are a good fertilizer for acid-loving plants like hydrangeas, azaleas, carrots, and blueberries. In fact, used coffee grounds are safe for any plant, they are good soil additives, and they attract plant-friendly earthworms.
Ready to try it? Sprinkle used coffee grounds directly on the soil at the base of your plants, and then water the area to let the grounds settle into the soil. Or add used coffee grounds to a 5-gallon bucket of water and let it sit overnight before using it to water your plants. Used coffee grounds are also a great addition to a compost heap.
