Why is my lawn black?
If you have recently applied a moss killing product this is a sign that the moss is dying which is great news. Wait two weeks for it to completely blacken and then rake (or scarify) the dead moss up. Make sure the dead moss is not put into your garden waste bins, it is important for the moss killing ingredients to degrade before they can be put into the bin. We recommend you leave them to one side for 6 months after that time it is fine to go in the bin.
