Will copper sulphate kill moss and not harm couch?
I have peat moss growing in couch grass. Will copper sulphate kill the moss and not harm the couch?
To remove the moss in your couch grass you can use a product called sulphate of iron. It will kill off the moss without harming your lawn. The sulphate of iron is applied to a moist lawn, left for 2 days and then watered thoroughly after 2 days. In that 2 day period the sulphate of iron will kill the moss that is growing in the lawn area.
