Hydroseeding is a hydraulic planting method that is the most up-to-date system known for planting lawns, ground covers and establishing plant material on slopes for erosion and dust control. All the materials (water, seed, fertilizer, and the fiber mulching material) are combined in a large tank. They are thoroughly mixed, then sprayed through a high-pressure nozzle onto the ground.

After the application process has been completed, the wet fiber molds and clings to the soil particles. Not only is this why it works so well for erosion prevention, but this action brings seed and fertilizer into closer contact with the nutrients in the soil, which speeds germination and growth. The mat of web-like fiber mulch also helps hold the seed in place during heavy rainfall or irrigation and conserves moisture during drought. The mulch protects the seeds during germination, then it breaks down over time and provides nutrients for the new grass. With proper conditions, lawns can be ready to mow within 30 days.

One of the advantages of establishing plant material from seed is the great variety of seeds available in any number of combinations. The technique makes planting possible as a one-step application, under nearly all weather, soil, and slope conditions for a very low cost.

Hydroseeding costs are comparable to hand seeding, taking into consideration the cost of seed, fertilizer, top dressing, and renting the equipment needed for hand seeding. Hydroseeding costs an average of 70% less than sod lawns, and there is a substantial savings of time. Soil preparation for hydroseeding is the same for hand seeding or laying of sod. The advantage over hand seeding or laying of sod is labor; you do not have to scratch the seed in, roll it, top dress it, or load and place heavy sections of sod.
