Osmo Progreen Moss Remover for lawns is grass fertiliser that also kills moss. The fertilser is released slowly over a period of 3 months. It is made up of 6-2-20 (NPK) and contains added magnesium to give a rich green colour.
It Kills moss by dehydrating it, causing it to break down slowly into dust, which in turn acts as an organic matter feed for the lawn. It does not contain sulphate of iron and will not turn the moss black, will not stain driveways or patios, and does not need to be scarified.
