Iron sulphate on lawn
Just wondered if you may be able to give me some advice on applying Iron sulphate to my lawn to give it a bit of a green up. My lawn is 85m2 so i was thinking of just using 85g of the iron sulphate. Im just not to sure how much water i would need to mix with the 85g to apply it. I have a 10l watering can that i plan on using. Do i simply just fill up the can with water do a test run with just water and see how far round the lawn i get then work out how many full cans of water it will take to finish and just devide the mixture evenly between them?
Hope you may be able to assist
