Doff’s Lawn Moss Killer Sand uses Iron Sulphate known to the ancients as copperas which doubles as a moss killer and a grass fertiliser at the same time! The granular sand formation is designed so that it can easily be sprinkled by hand or machine at a density of 80 grams per square metre meaning that a 3kg bag will treat 37.5 square metres of lawn.
