Certain applications require either sod installation or hydroseed. For example, the average homeowner wants instant gratification, so sod is the most common in residential applications. Sod also immediately helps with erosion control and allows the family to get on the lawn within two to three weeks. Hydroseed on the other hand takes up to a month to germinate at least 35% on average. That means that the lawn doesn't come in for quite some time. If you can stand to wait, hydroseed ultimately gives the best lawn in the long run due to it growing on the site where it was planted, deeper root development, and choice of seed for the specific environment.
Typically hydroseed is cheaper, but the ground preparation can be extensive.
Sod is usually available in mid-April. Hydroseed can be applied when the soil warms.
