Use our calculator to determine how much material you'll need
If you live in where rainfall is naturally low, or where limestone is abundant in your soil, you¿ll likely need to take steps to lower your soil's pH. Usually, the best product to use is 100 percent finely ground sulfur, a mined mineral. Sometimes called "flowers of sulfur," this is the same material that gardeners use as a fungicide and is the material this calculator is based upon.
