Granular Gypsum is useful for landscapers or homeowners preparing to plant seeds or lay sod. Before planting, use five pounds of Granular Gypsum for every fifty square feet. For best results, till into the top six inches of soil.
After a lawn has become established, reapply Granular Gypsum at 5 pounds for every 100 square feet. Trees and shrubs can also benefit from this product. Remember to give all plants adequate water so they can absorb the Granular Gypsum.
