Hydroseeding blends can include any number of varieties of grasses including fescues, ryegrass, wheat grass, bluegrass, and others.
For acreages or commercial projects seed blends can be chosen to have lower maintenance requirements, high wearability, and better drought and heat tolerance. Municipal and industrial blends will often include native grasses and grasses and plants designed to grow in particular conditions such as wet areas, pasture lands, and for soil stabilization.
The average residential blend contains: fast-germinating ryegrass which acts as a nurse crop to protect the other grasses as they germinate; fescues which germinate more slowly than the ryegrass and give a lawn excellent wear and drought tolerance; and bluegrasses which give lawns the deep green color and the soft feel that most customers desire for their lawns.
