How do I use this iron sulphate to 'green up' my lawn?

To green up your lawn we'd recommend using a 1% solution, dissolving 1g of iron sulphate per litre of water. You should then distribute 1 litre of water per square metre of lawn.

If, over the first week, the grass doesn’t show much change, then increase the percentage and water the lawn again.
