How do I use this iron sulphate to kill moss?

If rain is forecast, we recommend sprinkling roughly 5g to 10g of iron sulphate per square metre of lawn.

If no rain is forecast, we recommend dissolving 10g of iron sulphate in one litre of water and then watering at a rate of one litre per square metre. 

For example, if no rain is forecast:
  • For a 10m2 lawn, use a maximum of 100g of iron sulphate in 10 litres of water 
  • For a 100m2 lawn, use a maximum of 1kg of iron sulphate in 100 litres of water
  • For a 1000m2 lawn, use a maximum of 10kg of iron sulphate in 1000 litres of water
