@usmccarterfamily0: Worm castings (earthworm manure) are a nutrient-dense, natural soil amendment that improves #plant health, boosts soil structure, and supplies beneficial microbes. They enhance water retention in sandy soils while improving aeration in clay soils, providing a slow-release source of nutrients without the risk of #fertilizer burn. They contain readily available #nitrogen phosphorus, and potassium (NPK), plus trace minerals like #calcium #magnesium and iron.
