What is that green stuff that is sprayed on areas that need new grass?
It is called hydromulch. Hydromulch consists of cellulose fiber (paper), green dye and a gum-based tactifier (sticker) to keep it from washing away when it rains. The hydromulch is mixed with grass seed, water and fertilizer in a hydro-mulcher machine. The machine consists of a tank, a pump and a spray gun. The mixture is applied to a prepared soil surface and aids in grass seed germination. It is also a good soil-erosion control measure until the turf is established.
