What is Hydroseeding?

“Hydroseeding is the hydraulic application of a mixture of seed, water and fertiliser to provide revegetation.”

Hydroseeding is the hydraulic application of a mixture of seed, water, fertiliser and tracking dye sprayed on topsoil to provide fast, economical and efficient revegetation.

Sprayed from a specially designed hydroseeding truck referred to as a hydroseeder, the truck keeps the mixture agitated during the application, ensuring even coverage.

Depending on the HydroTruck, the cannon, also referred to as a boom, is capable of spraying the mixture over 100 metres. This enables coverage in even the most difficult to reach areas.

Is hydroseeding the same as hydromulching?

Hydroseeding is distinguished from hydromulching by the fact that it doesn’t utilise a cellulosic fibre mulch in the mixture. Despite both words often being used synonymously, hydroseeding mixtures usually contain crop seeds of a single origin and a fertiliser mix that is based on an initial soil test of the site.

Benefits of hydroseeding

The complex mixture of minerals, fertiliser and seeds provide a number of benefits. These include:

Water repellent

The binder/tackifier essentially acts as a “glue” that holds the seeds to the soil so that the seeds remain in place long enough to germinate without being washed away in rainfall.

Wind resistant

Hydroseeding solutions are usually utilised where mulch is not needed as the soil is healthy and irrigation is adequate, with binders and tackifiers added to the mixture to reduce the erosive forces of wind and rain on the seeds.

Covers large areas

Hydroseeding is an effective and viable option for vegetating large expanses of land quickly and easily. This includes land that is flat, hard to access or significantly sloped.

Faster revegetation

Hydroseeding can revegetate an area much quicker than direct seeding methods such as broadcast or drill seeding.

Cheaper than turf

Hydroseeding is a far cheaper way to revegetate an area than rolled turf.

Difficult or dangerous areas

Hydroseeding can be used to revegetate areas that are difficult or dangerous to access as well as flat areas, batters and slopes, which makes the task of providing erosion control for verges and soil stockpiles much easier.

Native vegetation

Hydroseeding can also cater for sites that require native vegetation. We can provide custom seeds and fertiliser blends to produce as little impact on the environment as possible.

Attractive appearance

The tracking dye added to the hydroseed mix not only ensures you receive full revegetation coverage, but it also has an attractive appearance that looks far better than an area covered with straw or sod.

Reduction in labour costs

Other revegetation methods are generally a lot more expensive due to the additional labour resources needed to seed or turf a substantial area.

When was hydroseeding invented?

A Connecticut highway worker by the name of Maurice Mandell discovered hydroseeding while working on the steep embankments of the expressway in the 50s.

By mixing seed and keeping it suspended in water it could be sprayed directly onto the ground surface from tanks.

Charles Finn, having previously designed the first straw mulch blower, took this idea and developed it into what is now known as the ‘Hydroseeder.’

Since the technique of hydroseeding was discovered in the 1950s, it has been referred to as many things and has many common variants such as hydroseed, hydro seeding, spray grass and hydraulic seeding.
