Will coffee grounds hurt your grass?Nope! Coffee grounds contain nitrogen, phosphorus, and trace minerals – all vital nutrients that promote lush green turf.
Coffee grounds are rich in nitrogen, which is a valuable component for composting, as it helps accelerate the decomposition process and provides essential nutrients for your plants and lawn.
Used coffee grounds should account for less than 20% of your total compost volume. Any more could mess up the pH levels in your soil and put a damper on stimulating healthier turf growth.
Composting these used coffee grounds not only reduces landfill waste but also creates a beneficial environment for nutrient-poor lawns by improving soil moisture retention.
