Down to Earth, Garden Sulfer Soil Acidifier, 5 lb

Garden Sulfur is a valuable amendment that can lower soil pH, help improve soil characteristics, and enhance plant nutrient availability. When dealing with problem soils, such as alkaline or saline soil, it is important to address the conditions that are negatively affecting plant growth. If your hydrangeas, blueberries or evergreens aren’t performing up to expectations, unsuitable soil pH may be the root cause. Alkaline soils (pH > 7.5) can cause nutrient deficiencies which may appear as stunted growth, yellow leaves, or other physical symptoms. Garden Sulfur contains two essential plant nutrients: calcium & sulfur. These nutrients provide numerous benefits and are key to myriad natural chemical and biological processes in soil and plants.

Application Rates:

1 cup ≈ ½ lb; ½ cup ≈ 4 oz; 1 Tbsp ≈ .5 oz

Apply Garden Sulfur in the spring and summer to lower soil pH. Most acid loving plants prefer a soil pH between 4.5 and 6.5. Performing a complete soil analysis (with lab recommendations) or using a soil pH home test kit before application is encouraged. If you do not know your soil pH, use the recommended application rates below:

Berries and Hydrangeas:

To prepare new gardens, apply 5-10 lbs per 50 square feet of planting area depending on soil pH desired. Incorporate into soil or cover with fresh soil, compost or mulch and water in well.

To feed established plants, apply 1 cup per plant in early spring, mix into soil surface or cover with fresh soil, compost or mulch and water in well. To encourage blue flowers on hydrangeas, soil pH must be 5.5 or lower. Test and apply seasonally as needed.
