Earthworm Castings

Dr. Earth Earthworm Castings are a rich, natural source of organic nutrients that improve soil structure, fertility, and improve microbial activity. Derived from high-quality earthworms, these castings are rich in beneficial microbes and organic material, fostering robust root development and enhancing nutrient uptake. Gentle enough for seedlings yet powerful enough for established plants, they’re ideal for all types of plants, including vegetables, flowers, lawns, and fruits. Earthworm castings improve water retention, reduce nutrient leaching, and help create a thriving, living soil. Use alone or mix with potting soil or your preferred soil mix for a nutrient, microbe-rich boost.
