Hydroseeding is a method of planting a lawn that is economical and very effective. Hydroseeding (or hydraulic mulch seeding, hydro-mulching, hydraseeding) is a planting process that uses a slurry of grass seed, fertilizer, mulch, and water, that is sprayed onto the ground to establish vegetation and control erosion. You can hydroseed a lawn by spreading this mixture with a hydroseed machine. This method is effective on all kinds of terrain, especially uneven terrain. Here is the basic method to hydroseed your lawn: 

Test the Soil:  Purchase a soil tester kit from any hardware or garden store. Follow the directions to test if your soil is acidic or alkaline. If you have acidic soil spread limestone (available at a garden store) on your soil according to the directions on the soil test kit. If you have alkaline soil, spread soil conditioner with sulfur or gypsum to your soil. 

Grade the Area to Be Seeded:  Use a rototiller to thoroughly break up the soil and get rid of any compacted soil clods. Rake the area completely to create a finely graded soil that will readily accept the seed you are about to spread. 

Measure the Area to Be Seeded:  Take accurate measurements of the area you wish to seed. The proportion of seed, fertilizer, and mulch that you will need will depend on the size of the area that you wish to plant. 

Get a Hydroseed Machine:  Purchase or rent a hydroseed machine at any hardware or garden supply store. Follow the directions to prepare your machine by thoroughly cleaning it and connecting it to an outdoor water spigot that is near the area that you wish to plant. 

Mix the Hydroseed Mixture:  Purchase grass seed, fertilizer, and mulch, and mix it together in equal proportions. Pour this mixture into your hydroseed machine and turn on the water. 

Spray the Hydroseed Mixture:  Spray the seed mixture with the hydroseed machine on the area you wish to plant. Spray the mixture slowly and evenly to thoroughly cover the area. Hold the nozzle of your hydroseed machine close to the earth to avoid overspray. 

Maintain Your Seeded Area:  Keep your newly seeded area thoroughly moist with plain water for the next two weeks by watering it 2–3 times a day. You need to keep the area wet at all times without creating standing water puddles. Do not walk on or touch the newly seeded area as you can easily cause bald spots if you disturb the seed. Do not allow pets to urinate on the area as urine can interfere with new seed growth. 

After Seeds Begin to Sprout:  Reduce your waterings to 1–2 times a day for the third and fourth week after you have planted your lawn. If you notice any areas that have not sprouted grass, replant them with more hydroseed mixture. 

Maintain Your Lawn:  Once you have a growing lawn, maintain it by regularly watering it, fertilizing it with fertilizer, and mowing it to encourage more growth.

Hydroseeding your lawn is a simple and effective way to plant and maintain a new lawn. The most important thing that you can do for success, is to keep the area moist without standing water puddles. Within a month you will have a thriving lawn that will elicit many compliments from your neighbors and guests.
