(use a blend of 50% native soil to 50% sphagnum peat)3) If your soil pH is greater than 5.5, incorporate elemental sulfur into the top 6 to 8 inches of soil at the following rates to reduce your soil pH by 1 unit:For sandy soils - 1.0 lb per 100 square feet (about 2 cups)For loamy soils - 2.5 lb per 100 square feet (about 5 cups) For example, if the pH of your loamy soil is 6.0, incorporate 5 cups of elemental sulfur per 100 square feet (or ½ cup per 10 square feet). After mixing in the elemental sulfur, mix in 1 to 2 cubic feet of sphagnum peat moss per plant.
