Planting rates vary between grasses depending on the size of the seed. Each grass seed we offer specifies the planting rate per 1,000 square feet at which the grass seed should be planted. For example, a larger seed such as turf type fescue will be seeded at 10 lbs per 1,000 square feet. A smaller seed such as Kentucky Bluegrass may be seeded as low a 2 lbs per 1,000 square feet. Both of these seeding rates will end up giving you approximately 16 seeds per square inch which is the rate at which lawn grasses should be planted. See each grass seed page of our web site for planting rates, see the bag label when your seed arives, or check this chart below for the planting rate, germination time, and typical mowing heights.
