Hydroseeding is a planting procedure, also known as hydraulic mulch seeding, hydraseeding and hydro-mulching. Hydroseeding involves the use of mulch and seed slurries. The mulch and seed suspensions are placed into a tank and then sprayed over the ground in a smooth, even layer. The tanks must either be mounted on a trailer or a truck. It speeds the process of planting large areas.
The process of hydroseeding involves fiber mulch, fertilizer, water, seed and sometimes lime being mixed together inside a tank, and then applied directly over a prepared ground, using a spray hose. Once the lawn area is thoroughly sprayed, the moist fiber mulch then works to produce a bond with the soil, and also gives the seeds a water-retaining layer to defend them against the sunlight, erosion and wind. Once the seeds start to germinate, and the fiber mulch gradually decompose, providing the soil with nutrients.
Hydroseeding is a cost-effect and rapid way to seed a new lawn. The process is also especially effective on sloping lawns and hillsides to provide erosion control.
Like sod, hydroseeding brands offer a limited selection of types of grass and fertilizer. As with standard seed planting, hydroseeding should only be conducted just before the growing season for the most successful results.
Hydroseeding began in the United States during the 1950s. The initial commercial hydroseeder was introduced towards the beginning of the 1950s, and served the purpose of quickly shooting out fertilizer and seed over large areas of lawn. The procedure made its way to the United Kingdom in the early 1960s.
Because of all of the logistics and details (including cost and expertise required) involved in hydroseeding, most people do not perform the procedure themselves, and instead hire hydroseeding companies. Before the hydroseeding company sprays the lawn, you can prepare for the process by grading the lawn and getting the soil ready.
