Hydro Mulching 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 in a uniform layer; helicopters may be used in cases where larger areas must be covered.
Hydro Mulching is an alternative to the traditional process of broadcasting or sowing dry seed. It promotes quick germination and inhibits soil erosion.
The mulch in the Hydro Mulching mixture helps maintain the moisture level of the seed and seedlings. The slurry often has other ingredients including fertilizer, tackifying agents, green dye and other additives.
Hydro Mulching is used to seed grass on commercial sites (highways etc.), golf courses, lawns and areas too large, inaccessible or unsuitable for conventional methods. Starting a lawn by
Hydro Mulching is considerably cheaper than laying sod/turf and quicker than using seed. It is also used to spread mixtures of wildflower and tree seeds or turf grasses for erosion control. The process is called sprigging (or hydro-sprigging) when the slurry contains stolons or rhizomes instead of seed.
