Hydroseeding (or hydraulic mulch seeding, hydro-mulching, hydraseeding) is a planting process which utilizes a slurry of seed and mulch. The slurry is transported in a tank, either truck- or trailer-mounted and sprayed over prepared ground. Hydroseeding is an alternative to the traditional process of broadcasting or sowing dry seed. The slurry often has other ingredients including fertilizer, tackifying agents, green dye and other additives.

[1] Usefulness of Hydroseeding The first commercial hydroseeder was invented in United States in the early 1950s and was used in the United Kingdom in the 1960s. Matthew (2011)a wetland in a riparian forest zone at the lower Colorado River was restored by a direct seeding method and suggested that hydroseeding which contained various riparian seeds, mulch, and tackifiers could increase the placement of seeding branches in cleared land. [2] Advantages of Hydroseeding

[1] If planting a relatively large area, hydroseeding can be completed in a very short period of time. Hydroseeding can be very effective for hillsides and sloping lawns to help with erosion control and quick planting. Hydroseeding will typically cost less than planting with sod, but more than regular seeding. Results are often quick with high germination rates producing grass growth in about a week and mowing maintenance beginning around 3-4 weeks from the date of application. Fiber mulch accelerates the growing process by maintaining moisture around the seeds thereby increasing the rate of germination.
