Worm castings, also known as vermicompost, are nutrient-dense, dark, and crumbly substances produced by composting worms. These castings are rich in essential nutrients like nitrogen, phosphorus, and potassium, which are vital for plant health. They enhance soil structure by improving aeration, drainage, and moisture retention, leading to stronger, more resilient plants. Additionally, worm castings are teeming with beneficial microbes that further enrich the soil, promoting a thriving garden ecosystem. Their natural, slow-release properties provide a steady supply of nutrients without the risk of over-fertilization, making them an invaluable addition to any garden or composting system.
