Hydro-Seeding 101

 

Hydroseed is a mix of grass seeds, mulch, fertilizers, bonding agents and water. The mix is sprayed on to topsoil and transforms into a uniform lawn in a few weeks, depending on the season and climate where it is applied. Hydroseed typically germinates faster than seeds alone, because seeding requires several days of watering to reach the same level of moisture saturation the grass needs to grow.

In most areas, hydroseeding can be done in the spring, fall and early summer. Soil preparation is the same for all types of grass: remove all debris, till the soil adding necessary fertilizers for the site's condition, grade and level for smooth surface and then lightly pack and moisten the yard. After a lawn has been hydroseeded, water it lightly for three to four weeks, keeping the surface moist. In addition to preserving moisture, the mulch in the hydroseed mix will help prevent erosion and runoff In most cases the grass will be ready to mow in three to four weeks. Keep traffic low for two to four months after the lawn is established, and avoid normal to high use until the lawn has had a year to take root.

The advantages of hydroseeding are:

*       Reaching difficult areas.
Steep slopes along roadways and in new developments would be very difficult to seed using any other method, due to their size and poor accessibility.

*       Saving time.
One hydroseeding application replaces three separate applications of seed, fertilizer and mulch.

*       Jump start.
Soaking seed in water begins the germination process immediately. The term 'imbibition' refers to seed absorbing moisture and swelling, beginning the germination process.

*       Less weeds.
Hydroseeded areas have less weed seed introduced than ones mulched with straw.

*       Saves money.
Hydroseeding is usually less expensive than other seeding methods due to the streamlined process combining several separate steps into one process.
