Hydroseeding is the best way to get your  lawn growing fast. Hydroseed is a mix of paper mulch, 19,19,19 fertilizer, seed and water. Mixed up hydraulicly and sprayed out to get a well mixed even coat of grass bed. This mixture forms a perfect growing bed for grass. If the temp is over 50 degrees 24 hours a day grass will germinate 7 to 10 days. Once the little blades pop up it takes off like crazy. You do have to water. Every new lawn must be re-fertilized at the first sign of yellowing or red tint.
