Planting grass seed at the proper time is crucial for your lawn's success. In northern Ohio, the best time to seed a lawn is between Aug. 15 and Sept. 15, but you can plant as late as Oct. 15. In central and southern Ohio, the optimal month is September, but you can plant as late as Oct. 30. If you miss those planting windows, it is best to wait and plant your grass seed in spring.
Choose a high-quality seed that contains a blend of grass types and little to no weed seed fillers. A good mix for Ohio includes tall fescue, Kentucky Bluegrass, fine fescue and rye grass.
Loosen clumps of soil and remove roots or rocks by raking the area where you plan to plant your grass seeds.
Use a seed spreader to evenly distribute the grass seed.
Spread straw mulch over the newly planted seeds. This is especially important because of Ohio's cold climate. The mulch insulates new seeds from harsh weather variances. Another benefit of applying straw mulch is protection from soil erosion during the state's wet fall and winter months.
Water the entire area thoroughly for first two weeks after you plant the seeds unless your area of Ohio is getting regular, soaking rain. Newly planted seeds need a lot of of water. It is crucial to the success of growing a new healthy lawn.
