Hydroseeding was first used in the United States in the 1950’s and in the UK later in the sixties. Today, this method is still used to encourage grass growth in lawns, farming, and vegetation in wide deforested land areas. Compared to another planting method called broadcasting, hydroseeding covers a wide land area in a shorter period of time. The rate of germination is also faster due to the presence of mulch and fertilizers. Aside from providing constant ideal moisture to seeds, mulch and fertilizers prevents birds and insects from eating the seed. Thus, the seeds develop a healthy root system because it is undisturbed by animals and insects. In addition, less water is used, unlike broadcasting.
Hydroseeding is ideal for covering large surface areas within a short period of time. It is beneficial for reintroducing vegetation to sloping lawns and hillsides. It also involves less manual labor and thus, less employees, although set up costs can be more expensive the broadcasting because only professionals should spray the mixture of slurry, fertilizer, mulch and water over the land area. Nevertheless, this planting method yields a high germination rate. Grass grows uniformly within 7 days and completes growth within 4 weeks, provided that the land area will not be disturbed or stepped on. Compared to sod, this planting method is quicker and 3 to 5 times cheaper. If you have a large land area to cover, then this method may be suitable for your needs. Remember however, that this should only be done by professionals.
