Generations of creating amazing lawns 

Our Work Speaks Volumes

We’ve collaborated with an array of wonderful clients on the most rewarding (and award-winning) projects.

SINCE 1975

Hydroseed Spokane

Hydroseeding is a process using a specialized machine to apply a mixture (slurry) of water, hydroseed, lawn fertilizer, mulch, and powdered glue (tackifier). We have a Finn Hydroseeder mounted on a 3-ton flatbed truck. The hydroseeding machine has an independent engine, paddles to mix the slurry, and a valve system to shoot the hydroseed through a fire hose out onto the proposed grass lawn or erosion area.

Why Hydroseed Works So Well
When the slurry is mixed it adds nutrients to the seed and begins the germination process. Then the hydroseed slurry is applied to the soils surface and it creates a protected environment for the seed to flourish.  The next step is for the seed to get the proper water, temperature, and sunlight.  This is where a sprinkler system is ideal to mimic spring showers bring April flowers.  (A brief rain shower followed by a period of sun and then another rain shower)

Hydroseeded Lawn Versus Sodded Lawn

 The cost of professionally hydroseeded lawn is approximately 85% less than the price of a professionally installed sodded lawn. A hydroseeded lawn is less susceptible to disease than a sodded lawn. Larger lawn areas is where the relatively low cost of hydroseeding becomes extremely practical compared to sod. Whether you decide to go with sod or hydroseed Landsite Development recommends our professional site and soil preparation.


The same hydroseeder process applies to both erosion control and lawn seeding. The only difference is the slurry mix in the hydroseeder machine.
