About Hydroseeding


Preparing and seeding a new lawn can seem overwhelming at times. After the manual labor of preparing the area, a homeowner wants to ensure the grass seed will grow properly. Hydroseeding is an application of grass seed that involves spraying a seed mixture directly onto the lawn. The application is easy and guarantees the lawn is covered with seed without the additional labor of applying straw or sheet coverings for protection.


Hydroseeding is a lawn seeding process that mixes grass seed, fiber mulch, fertilizer and water for application. The mixture is stored in a tank and sprayed directly onto the lawn. The fiber mulch looks like chopped up paper and adheres to the ground, giving the seeds protection, moisture and nutrients when it decomposes.

Soil Preparation

Soil preparation is important for hydroseeding to give the best results. The soil and lawn must be clear of debris and packed smooth. Plow or till the lawn to loosen soil which also allows for easy removal of debris. Fertilize the soil based on recommendations for the soil type. Smooth the ground and flatten with a lawn roller. Gently spray the soil with water to moisten prior to application.

Seeding and Maintenance

The type of seed used for hydroseeding will vary by region based on varieties that grow best in that area. The wet mixture has a green dye mixed in to mimic the color of grass. This dye will fade several days after application and has no effect on seed growth. Water is needed for seed germination and should be applied two to three times a day for the first week after hydroseeding. Do not saturate the lawn or create water puddles as this will prevent grass growth. Also, do not walk on a newly seeded lawn as this will cause indentations and uneven growth. Germination will occur five to seven days after application, with a strong grass growth after approximately eight weeks.


Hydroseeding is easy to apply and produces a fast grass growth compared to manual seeding. The application is less time consuming and costs less than applying sod. The mulch used does not contain weed seeds, which is common with straw placed over newly seeded lawns. The fiber mulch adds additional nutrients to the soil as it decomposes and helps maintain moisture levels during early germination. Hydroseeding works well on hillsides and sloping areas where erosion is a problem.


Hydroseeding is a more expensive than manually laying seed and requires special equipment for application. In most cases, hydroseeding cannot be done by the homeowner and requires contracting with a company. Many hydroseeding companies have a limit on the number of grass seed varieties available.
