Can anyone tell me the best strength to dilute iron of suphate in water for killing moss in a lawn please? Is 30grms per litre or water too strong or too weak?


Are there no guidelines on the packaging? 

Not for using as a moss killer on a lawn.

It depends on how you wish yo apply it, in a watering can or in a calibrated knap sack sprayer.  If in the later i would recommend a rate of 2 to 8 kg per hec in 300 to 600 ltrs of water per hec.  Sulphate of iron will not completely  kill moss, it is not translocated to the roots, it will desiccate the plant and knock it back and will slow its invasion.  If i can be of any more help please mail me
