Hydroseeding is becoming more and more popular as an effective means of establishing a new lawn. It is a process that utilizes a mixed media of cellulose fiber, seed, fertilizer and water. After being thoroughly mixed into a soupy consistency, this media is sprayed on the lawn by machine. Sprouts will appear in as little as three days and a fully established lawn will be
achieved in three weeks or less.

Hydroseeding provides a moisture retaining mulch that allows the undisturbed seed to germinate and root quickly.

advantages of hydroseeding

-Protection of seeds from heat and birds
during germination process.
-Soil temperature is maintained.
-More even application of seeds than is
possible with broadcast seeding.
-Especially effective in keeping seeds from
being washed away on slopes.
-Provides added organic components to
enrich the soil after the lawn is established.
-No need to remove straw as is the case with
broadcast seeding.
-Retention of moisture as seeds sprout.
-Allows for a better root formation as opposed
to sodding.

site preparation
Before hydroseeding, the site must be prepared to
rid it of all grasses and weeds. More than one application
of weed killer will do away with seeds as they
germinate. Multiple applications eliminate future problems
by ending the life cycle of the weeds. The time of
year and degree of weed infestation in your lawn will
dictate the needed course of action.

seed selection
The seed mixture used to hydroseed will depend
on the requirements of your lawn. The amount of sun
and shade is one factor. Special seed mixtures may be
needed for special requirements such as slopes.
  

after care
Be sure to water your hydroseeded lawn consistently
for the first two weeks. This is very important.
The amount of watering necessary will depend on the
weather in your area. Generally, during the first week,
water every day in the morning and again in the
evening. Then water every other day until there is
enough grass for a first mowing. The goal is to keep it
moist at all times. Your grass seedlings will die if they
are allowed to dry out. Be sure to consult with your
lawn care professional to determine the exact water
needs of your hydroseeded lawn.
Fertilizer is included in the hydroseeding mixture.
This ensures that the grass will have every thing it
needs for healthy growth. Additional fertilizings should
be done every other month during the growing season.
