Hydroseeding is one of the most cost effective solutions to establish vegatation quickly and reliably. Whether your building a new home and installing a new lawn, repairing an existing lawn, or clearing off a wooded lot, soil erosion can quickly become a serious problem once the rain starts. During the growing season for grass, which typically runs from March to October in our region, hydroseeding is a very effective way to prevent the erosion problems that come with exposed topsoil.
Hydroseeding works by applying a slurry mixture of seed, water, lime, fertilizer, and mulch. This mixture provides optimal conditions for the grass seed to germinate, sprout, and grow quickly. You might be wondering how this mixture doesn't get washed away by heavy rain? We use an additional additive in the mixture called a tackifier, which is a binding agent that helps the seed and mulch adhere to the topsoil. This binding agent also acts like a protective film that will help shed away heavy rain and gives the seed time to establish roots.
New grass seed needs to be continously moist during the first several days in order to achieve the best germination rates. This generally requires the seeded area to be watered twice daily for the first week, and once daily during the second week. Areas where grass is slower to appear may need watered a little more depending on the slope, amount of sunlight, and soil conditions. Areas where grass has appeared should be watered regularly, about an inch per week. Water crystals can be added into the hydroseeding mixture to help retain more water in the mulch, and reduce the watering requirements. We typically recommend the water crystals during the summer months when the rain is less frequent and the temperatures are warmer, or when the homeowner doesn't have the resources to water the lawn as frequently as recommended.
For best results, the soil needs to be prepped prior to applying the hydoseeding mixture. Prepping soil typically involves loosening/tilling the top 6 inches of the soil so that the new grass roots can penetrate the soil easily. Sandy or clay soils should be mixed with a couple inches of soil amendments (decomposed organic matter) in order to change the soil texture to create a healthier lawn.
