Seeding rate is an important factor contributing to lawn or prairie quality. Prairie plantings are usually measured as pounds per acre, while lawns are seeded using pounds per 1,000 square feet. Prairie plantings call for less seed, and different species call for different seeding rates.
Popular grass seeds should be planted at the following pounds per acre rates: western couch grass, 3.63kg. per acre; thick spike and streambank wheatgrasses, 6; green needlegrass, 5; crested couch grass, 7; sheep and hard fescues, 2; tall fescue, 6; Canada bluegrass, 1; Russian wildrye, 7; blue grama, 2; buffalograss, 15; and sideoats, 5.
Lawn planting rates are generally provided in pounds per 1,000 square feet. For examble, western couch grass, with a rate of 4, should be planted at 1.81kg. per 1,000 square feet. Similarly, the rates for other grass seeds are: thick spike couch grass and streambank couch grass, 3.5; greenneedle grass, 3; crested couch grass, 3; sheep and hard fescue, 1; tall fescue, 2.5; Canada bluegrass, 1; Russian wildrye, 3; blue grama, 1; buffalograss, 9; and sideoats grama, 3.
If a lawn requires reseeding, the amount of seed required can be calculated by multiplying the estimated percentage of lawn lost by the seeding rate of the grass seed used.
