Getting grass to grow in some areas is a difficult task, while other areas don't seem to have a problem at all. To ensure your grass gets off to good start, you may need to improve the soil, use additives and do some hard work. Once planted, proper care will help grass grow healthy blades and aid in its progress to becoming a lush lawn of which you can be proud.
Test the soil with a soil test kit. This will tell you the pH level of the soil and other nutrient levels. Soil needs to be just barely acidic to grow healthy grass. A pH between 6 and 7 is optimal.
Add fertilizer to the soil based on the results of the test to get it within the 6 to 7 range. Use a spreader to apply the fertilizer. Spread quantities based on the recommendations of the manufacturer.
Till the soil and fertilizer to mix them and infuse air into the soil. If it is poor-quality soil, mix in organic material, such as mulch. If you already have a lawn, use an aerator to loosen the soil without tearing up the entire lawn.
Rake the yard to smooth out or remove clumps. For yards with grass, this will also help dethatch the dead grass.
Spread the seed based on the instructions of the seed bag. Different seeds call for different densities. If you are overseeding, look at the overseeding quantities. There is no need to waste seed. Spread in a criss-cross pattern to ensure full coverage.
Cover the grass seed with straw. For overseeding only use a thin layer.
Water the lawn every day for about a month until the new grass grows. Then, taper back to watering 1 inch a week.
