Odorless and non-toxic Earthworm Castings are a natural organic fertilizer and outstanding soil amendment. Will not wash out with watering or burn delicate plants. Castings rival chemical fertilizers in their nutrient composition by providing a concentrated source of calcium, magnesium and nitrogen. Castings are safe to use on annuals, perennials, seedlings, even cacti and succulents.
