Hi-Yield Aluminum Sulfate - 4 lb


This sulfate is used primarily to acidify soil. This helps to create an acid soil condition which is desirable to the growth of certain plants, such as azaleas, rhododendrons, camellias, gardenias, blue hydrangeas, junipers, yew, cypress, magnolia, oak, pine, and others. This can change the color of white or pink hydrangeas to blue.
