Hydroseeding

Hydroseeding is a way to plant grass and other groundcover by spraying a liquid mixture rather than scattering dry seed. The slurry combines seed, water, a wood or paper mulch, fertilizer, and often a tackifier that glues everything to the soil. A tank pumps it through a hose, coating bare ground in a single even pass that is usually tinted green so the operator can see what has been covered.

The method sits between hand-sowing and laying sod. Hand-sowing is cheaper but slower to fill in and prone to washing away, while sod gives an instant lawn at a much higher price. Hydroseeding lands in the middle: the mulch holds moisture and shields the seed, so germination tends to be quicker and more uniform than broadcasting seed by hand, and the cost stays well below rolled sod.

In a backyard project, hydroseeding is most common after grading on a new build, on a slope where loose seed would slide off, or when reseeding a large area that has gone bare. The contractor preps and levels the topsoil, sprays the slurry, and the homeowner keeps it consistently damp until the grass roots take hold, which often takes two to three weeks.

For a homeowner or contractor, the appeal is coverage speed and erosion control at a moderate price, especially on bare or sloped ground that bare seed would not hold. The trade-off is the watering discipline of the first few weeks; let it dry out once and patches can fail, so reliable irrigation matters as much as the spray itself.

It pairs naturally with other lawn and soil work, so it helps to understand topsoil, overseeding, lawn aeration, and how a swale directs runoff on a graded site.
