This water soluble powder can be used any time to lower soil pH.  Ideal soil pH for shade-loving mosses is 4.5 - 5.5.  Anything under 6.0 should be fine.

To lower soil pH by application directly to bare soil:

The 5 lb bag of wettable sulphur can be used one of two ways: 1) Either dry in a drop spreader, or 2) "Wet" - diluted in water and sprayed from a pump sprayer.

  1. For use DRY in a drop spreader use 3 lbs of sulphur per 100 square feet of area. This will result in a lowering in pH of 1.0, or for example, from 7.0 to 6.0.
  2. For use WET in a pump sprayer use 1 lb. of sulphur to 2 gallons of water. Mix well in a 5 gallon bucket before pouring mixture into your pump sprayer. Apply all of the mixture over a 200 square foot area. Soak the bare soil thoroughly and use all the mixture to lower the pH 1.0 or (from 7.0 - 6.0 for example).

For use in helping to minimize grass, weeds, and or fungus in areas with pre-existing moss:

Always apply WET in a pump sprayer for this application. Dilute 1/4 cup of sulphur in 5 gallons of water. Mix well and pour into pump sprayer. This can be applied 2-3 times per year. If you are not seeing results within 2 months, up the concentration of sulphur until you see dieback of the grasses and weeds.


Avoid windy days for application. Best time of day for application is in early evening when temperatures are below 80 degrees.

When diluting the powder in water mix thoroughly in a 5 gallon bucket.

Always clean out pump sprayer with clean water after use.
