Worm castings offer gardeners a natural, eco-friendly alternative to hazardous toxic chemical fertilizers. Worm castings enhance your soils with nutrients as well as microbes to improve your soils health. Simply sprinkle castings around the base of the plant and gently work castings into the soil. Water plants as normal and watch the results. Castings will not burn plants and can be reapplied every two months. Great for houseplants, annual flowers, berries, succulents, fruit and vegetables, perennials, trees and all plants you love! 4 oz. package.
