Before planting a lawn, it is important that the area has a adequate covering of topsoil. A minimum of 20cm (8 inches) is best. A good topsoil base will allow the lawn to establish a strong root system.
The topsoil should be leveled to minimize depressions or low areas in the lawn. This will prevent water from pooling on the lawn, which may lead to drowning out and winter kill.
Before seeding you may choose to apply a starter fertilizer at recommended rate and mix throughout the soil with a tiller.
The seed should be spread evenly at the recommended rate. To ensure that strips are not missed the seed should be spread in two different directions. This can be done by spreading on half the recommended rate in one direction, and the other half in the other direction.
Once the seed has been spread it should be shallowly mixed with the topsoil. Using the backside of a rake works well to mix the seed and the soil. It is important not to pant the seed too deep. Deep planting can lead to poor emergence. A planting depth of 1/2cmd (1/8th inch) is ideal.
After seeding, the area should be packed with a lght lawn roller.
The soil should be kept moist until the lawn is established. However, over-watering should be avoided. If the lawn is over-watered the emerging seedlings may become diseased and rot off. Intense over-watering may also lead to seed being washed away by irrigation run-off.
When the lawn is 4cm (1 1/2 inches) tall it should be cut. A home lawn should not be cut shorter than 2 1/2 cmd (1 inch) to maintain the best appearance.
If there are areas in the lawn which are bare or thing, overseeding will help improve the appearance.
A good method for overseeding is to mix the required amount of seed with four times that amount of topsoil and then spread this mixture over the thin area. This should be lightly rolled and kept moist until the grass has established.
After establishment, a recommended spring and fall fertility program should be followed.
The best time to seed a lawn is either in the spring (Mid-May to the end of June) or in the fall (Mid-August to Mid-September). Seeding during the mid-summer should be avoided due to lack of moisture.
