HOW HYDRO SEEDING WORKS!

Hydroseeding is really a pretty simple process.   Water, seed, fertilizer and and a protective mulch is mixed in a tank and sprayed onto the ground.

The first known hydroseeding unit  was built by the state of Connecticut long ago.  It was a jet type system and  used peat moss as the mulch agent.    When the Interstate Highway System was started during the Eisenhower administration there was a change in how roads were built.   All of a sudden roads went through the hills instead of over them or around them.  Conventional seeding techniques could not seed the steep hillsides created by highway construction and hydro seeding was the answer.   Something else happened too!  People noticed the grass that was planted with hydroseeding grew  faster and better.

The early machines worked well, but were expensive enough that only big seeding jobs could be economically justified.  In the last decade much more affordable machines have come on the market, and the advantages of hydro seeding are affordable to most any seeding professional.

Well, lets look at what exactly is in the mix that is sprayed onto a hydro seeding job.

WATER

Water in the mix acts as a carrier, and the contact of the seed and the water will jump start the growth process.  When extra fast germination is desired, it is also possible to pre-germinate seed for even faster growth.

SEED

Seed used in a hydro seeder doesn't need to be anything special.  Nearly any seed can be used and at the same application rate as other seeding methods.  These can include grass or lawn seeds, wildflowers, pasture seed, seed for athletic fields and seeds for erosion control such as crown vetch.

FERTILIZER

Fertilizer is usually used in the mix.  A high phosphorus "starter"  fertilizer that will stimulate root growth is the most commonly used

MULCH

Hydro seeding mulch is what gives it the green color.  It does more than just make it pretty, it helps protect the seed, and to seal in moisture.  It may be made from a paper or wood product or a mix.  If any accidentally gets on your walkways, driveways or house, it will not stain and can be washed off, or will just disappear on it's own.

OTHER ADDITIVES

Other products that may be added to a hydroseeding mix are products called tackifers that help hold the materials on a hillside in rainy conditions.  They also help seal moisture in to the soil and lubricate the machine.    A lime based product is added if the pH needs correcting.  Other products such as co-polymers that hold 400 times their weight in water and slowly release it as the moisture is needed, or growth stimulants,  More information on products that can be added to a mix are available on our machine site at www.turboturf.com
