The Magic Behind Coffee Grounds in Your Garden
Coffee grounds aren’t just waste; they’re a rich source of nitrogen, a key nutrient for lush, green foliage. More importantly, they are mildly acidic, making them perfect for plants that thrive in lower pH soil. Beyond nutrients, coffee grounds also improve soil structure, enhancing drainage and aeration, and can even deter some common garden pests. It’s a win-win-win!
