Hydromulching is a planting process which utilizes a slurry of seed and mulch. The slurry is transported in our Finn trailer-mounted tank, and sprayed over prepared ground in a uniform layer. Hydromulching promotes quick germination and inhibits soil erosion. Hydromulching is used to seed grass on commercial sites (highways/motorways etc.), golf courses, lawns and areas too large, inaccessible or unsuitable for cost-effective conventional methods. Starting a lawn by hydroseeding is considerably cheaper than laying sod/turf and quicker than using seed. It is also used to spread mixtures of wildflower and tree/shrub 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.
