Worm castings, also known as vermicompost, are the nutrient-rich waste produced by earthworms. These castings are packed with essential nutrients like nitrogen, phosphorus, and potassium, as well as beneficial microbes that enhance soil health. Worm castings are known for their ability to improve soil structure, increase water retention, and boost plant growth.
To use worm castings, mix them into the soil at a rate of 10-20% by volume. They can also be used as a top dressing around plants or brewed into a ‘worm tea’ for a liquid fertilizer. This versatile organic fertilizer is gentle enough to use on seedlings and young plants, making it a favorite among gardeners.
