Hydroseeding is a proven technology that has met the needs of contractors and homeowners for over forty years. Hyrdoseeding, also known as Hydromulching, is applying a slurry of water, mulch, seed, fertilizer, and often a tackifier to prevent soil erosion and provide an environment conducive to plant growth. A tank mounted truck equipped with a special pump and continuous agitation system is used. The pump forces the slurry through a top mounted discharge nozzle or discharge can be through 100 to 200 feet of hose. Tank capacities range from 1000 to 3000 gallons.
Water is added first and then the mulch, tackifier
(if used), fertilizer (if used), and seeds. Any coated seed would be loaded last. The mix is sprayed onto topsoil and transforms into a uniform lawn in a few weeks, depending on the season and climate where it is applied. Hydroseed typically germinates faster than seeds alone, because seeding requires several days of watering to reach the same level of moisture saturation the grass needs to grow.
There are reasons hydro seeding works so well. The seed is suspended in the nutrient rich slurry. The contact of the seed with the water in the machine triggers the germination cycle. The mulch layer seals in the moisture, and holds the soil in place. The seed is at an ideal depth for good results. The conditions are right to produce a lush green lawn in very short time. Mulch, seed and fertilizer are evenly distributed in the sprayed material. It is fast and irregular areas are a breeze.
