Cambridgeshire, United Kingdom
Hi. My lawn is full of worm casts and I am about to use, amongst other remedies, Ferrous Sulphate via a watering can to help 'keep their heads down' for a while. Also to help 'green up' the grass. My problem is I am unsure of the dosage in grammes per watering can as i do not want to blacken the grass. I have no moss on the lawn . How much should I add to a gallon watering can to cover a square metre. This will then give me an idea for the dose for the rest of the lawn which is approx 10 metres by15 metres. Hope this makes sense! Thanks, United.
