Hydroseeding is the process of combining seed, mulch, healthy soil amendments and fertilizers, with water, to form a thick slurry. This slurry is sprayed over the ground surface in a uniform layer to establish vegetation for erosion control.
The hydroseeding slurry is designed to provide even ground coverage. As it forms a barrier to keep everything in place, it will stabilize the seed to allow it to uptake the moisture, fertilizer and amendments it needs to grow quickly. The mulch fiber will help reduce erosion from wind and water and it will insulate the soil from temperature fluctuation. Eventually the mulch will break down and provide the soil with extra nutrients and organic matter.
A major advantage of hydroseeding is its ability to cover large areas which would be a challenge to access by traditional means. A typical day can yield 10 acres (4 hectares) of ground cover. This seeding process has the ability to retain up to 10 times its weight in water making it ideal for areas where watering would be difficult.
Due to the effectiveness of hydroseeding, costs are typically reduced compared to the price of sod. The favourable growth results that are achieved, coupled with the extreme cost savings makes hydroseeding a process of choice for many contractors and homeowners.
