Sulphate of iron is applied at 5 to 10 grams per square metre, which is not very much, and this can be mixed with sand 20:1 or dissolved in water.

Calibrate your watering can or sprayer by spraying water on a path of driveway and calculate the area that one fill will cover. Then mix the appropriate amount of sulphate of iron into the water.

But be sure to test spray an out of the way corner to test for results before treating the whole lawn … a mistake can cause severe damage, which will recover but look bad for a time, or else have no effect at all

Sulphate of iron is not a plant food as such … it is a source of sulphur which some soils benefit from. It is used because of its acidying effect on soil to help lime-hating plants to survive in limy soil. It is usually mixed mixed into soil before planting and left for a couple of months, applied at 100 g to 250 g per square metre depending on the liminess of the soil.
