My lawn reads above seven PH ON THE SCALE I have an area approx 1000sq feet to treat how much aluminum sulfate
To create more acidic soil for acid-loving plants, you would use Hi-Yield Aluminum Sulfate for shrubs at a rate of 1 lb. per 3 feet of height per 5 gallons of water. For trees, use 1 lb per inch of trunk diameter per 5 gallons of water.
