Iron sulphate can be used in a variety of ways. Take a look at our recommended dosage below: Iron Sulphate for Moss If you’re using iron sulphate to control moss, we recommend applying it dry during rain or when it is forecast to rain. Simply sprinkle the powder at a rate of 5-10 grams per square metre of lawn. If no rain is forecast, just dissolve the 5-10 gms per litre of water and spray using a watering can or sprayer.

Iron Sulphate for Grass Greening If you are already moss free and just want to condition and "green up" your lawn, first do a sample patch with a 1% solution (1 gram per litre). If it doesn’t show much change then increase the percentage but be careful not to overdose the grass. Increase the percentage a little at a time, too strong will damage the lawn.

Iron Sulphate to Acidify Soil You can also use Iron Sulphate to acidify your soil for your ericaceous plants such as Azaleas, Camellias and Rhododendrons. This will help lower the PH of your soil and make it easier for plants to absorb nutrients. The dosage for this is 20-35 grams per litre of water.
