I am applying this product to an established lawn based on a soil test. I can not til the sulfer granules into my soil as it will ruin my lawn. Should I apply before rain or use irrigation to help it penetrate the soil?
An elemental sulfur product such as Hi-Yield Soil Sulfur will work best when it's worked into the soil directly since the product creates the acidifying effect when soil microbes feed on it. So while you can potentially apply an elemental sulfur and water it in lightly, you would see faster results applying it after aeration or vericutting. Be sure that you do not flood or overwater the lawn after applying sulfur, and do not apply soil sulfur before the soil is about 55 degrees consistently in the spring.
A product with gypsum such as Hi-Yield Fast Acting Gypsum contains water-soluble sulfate for more immediate effects on the soil. Gypsum also aids in plant recovering, water and nutrient retention, and loosening compact soils.
