Hydroseed is a mix of seed, hydromulch, fertilizers, bonding agents, copolymers and water.
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. Not all types of grass can be grown with hydroseeding, but most common varieties—including Wheatgrass, Ryes, Bermuda, Buffalo, Zoyzia, Fescue—can be hydroseeded.
In most areas, hydroseeding can be done in the spring, fall and summer. Soil preparation is the same for all types of grass: remove all debris, till the soil adding necessary fertilizers for the site’s condition, grade and levelsurface and moisten the yard. After a lawn has been hydroseeded, water it often for three to four weeks, keeping the surface moist. In addition to preserving moisture, the mulch in the hydroseed mix will help prevent erosion, and runoff. In most cases the grass will be ready to mow in three to four weeks.
