Hydroseeding (also called hydraulic mulch seeding, hydro-mulching, or hydraseeding) is a planting process that uses a slurry of seed and mulch.After being transported in a truck or trailer mounted tank, the slurry is sprayed on the suitably prepared ground. Even if a large area is involved, hydroseeding can be completed in a very shorttime. It is an effective way to control erosion on hillsides and sloping lawns. Hydroseeding will typically cost less than planting with sod, but more than broadcast seeding. Fiber mulch accelerates the growing process by maintaining moisture around the seeds, increasing the rate of germination. The results are typically quick … grass growth occurs in about a week and mowing maintenance begins approximately 3 to 4 weeks after application.
