Grass not only serves as a typical lawn plant--it also provides erosion control in many areas. This common groundcover serves as vegetation in areas recently disturbed by construction and traffic. One method of grass planting involves spraying grass seed onto a prepared bed of soil. Many land developers incorporate this method into landscape establishment in business construction and personal yards. You can spray on grass seed and enjoy the speed and efficiency of this planting technique.
Test your soil. Regardless of application techniques, all lawns require sufficient soil nutrients and preparation for adequate germination and seed growth. Take a soil test to determine which nutrients your soil requires. Purchase a test kit from your local gardening department. Follow all the instructions included with the kit.
Prepare your soil for your new grass seed. Remove all existing vegetation, including weeds and brush. Toss out any rocks or debris. Ensure adequate top soil to areas disturbed by recent construction. Haul in topsoil to replace any depleted areas. Add any nutrients recommended by your soil test. Rake soil to provide a smooth surface for planting your new grass seeds. Water the area one day before spraying the grass seed.
Purchase grass seed formulated for use in hydro-planting. Mix the grass seed with the soil amendments, fertilizer and chemicals specified on the seed package. Follow all instructions included on seed package for mixing the slurry. Most mixes include a colored, cellulose fiber to show the area covered while spraying.
Rent a hydroseed sprayer from your local rental store or garden center. Following all instructions supplied for the hydroseed sprayer equipment, apply a uniform coat of slurry over the entire planting site. Avoid spraying the slurry on buildings, structures or nearby gardens and flowerbeds. Quickly remove any slurry that reaches beyond the desired planting site.
Water your sprayed grass seeds often while grass germinates. Keep the top 1/2 inch of soil slightly moist during the establishment period. Do not overwater. Avoid disturbing new grass during this period of initial growth.
