Directions for using Garden Sulfur
It is always recommended that you do a soil analysis to ensure the proper rate of application.
Plant Food Recommendation
Sprinkle 3 tbsp. Per 100 sq. ft. (1 tsp per plant) around the root zone. If possible, mix it in with your fertilizer and work it into the soil.
Soil Acidifier Recommendation
In the absence of a soil test, follow the rates below. Results can take up to several weeks depending on rate, soil temperature and timing of application. Reduce the rates by one-third for sandy soils and increase by one-half for clay soils. In general, the optimum range for blue hydrangeas is 5.5 – 6.0, and for blueberries it’s 4.5 – 5.0.
