Spring or fall is the best time for seeding turfgrass though grass can still be planted in the summer as long as there is sufficient water available for irrigation.

The first step in preparing the yard for seed is rough grading. This involves removing all debris, including large stones or wood left by construction work tilling the entire area to be planted and then raking and moving the soil to it get close to what the final grade will be. Where topsoil is to be replaced or brought in first spread it and letting it settle for a week or two. This is to make sure more soil is not needed in those same areas.

If the soil has a low organic matter content, work the recommended amounts of organic matter into the soil to a four-inch depth. Soil Pep, well-rotted manure, or Nutra-mulch may be used as sources of organic matter.

Till the seed bed to a four to six inch depth, making sure physical amendments if required are uniformly mixed throughout the soil profile. After this is completed, rake the soil as smooth as possible to complete the final grade.

Prior to seeding, broadcast starter fertilizer onto the soil. Sow a seed mixture that is adapted to use and climatic conditions of the site usually a Kentucky bluegrass mix for Utah. Dividing the total seed quantity into two equal parts, sow one half in one direction and the second half at right angles to the first with a mechanical seeder or spreader. Rake lightly or drag the area to cover seed no deeper than 1/3 inch. Roll lightly to firm soil around seed.

Immediately after seeding, irrigate enough to thoroughly wet the soil to a four to six inch depth. During the period of initial rooting, usually two to three weeks, irrigation should be applied to maintain adequate soil moisture. Do not allow the soil to dry during this period.

Peat moss may be used as a cover for the grass seed. It is beneficial to use during hot weather to help conserve water or on slopes to prevent the new seed from washing away. Consult nursery personnel with any questions.

Fertilize every six-weeks after the lawn is seeded, and wait at least four months before applying a lawn weed killer to the new grass.
