Lawn Irrigation FAQs, answered by experts

Properly preparing the soil for planting grass seed may include applying fertilizer several weeks before spreading the seed if you plan to overseed the lawn. However, in most cases involving a brand-new lawn, spreading a starter fertilizer along with the grass seed will give it the best chance of taking root quickly and growing strong.

Yes, you can put topsoil over sand to encourage grass growth. The topsoil will help to improve water retention and promote grass roots’ development, making it a recommended step of the seeding process. Adding a layer of topsoil will provide additional nutrients to the sandy soil, helping the grass grow and remain healthy through many seasons.

Yes, but the best approach is to apply fertilizer well before you actually sprinkle the seeds. Apply fertilizer with an NPK ratio somewhere around 10-10-20, or 10-10-10, depending on soil test results and the type of grass you're planting, about six to eight weeks before planting grass seed. This mix added to loosened soil will give the grass seed its best chance of getting off to a solid start. 

There are several possible reasons why your Bermuda grass is not thick, with the biggest reasons being too little water, too much shade, compacted soil, drainage issues, and too few nutrients in the soil. Bermuda grass needs frequent and direct sunlight to stay thick, so thinning grass is likely the result of a lack of sun. 

Water your yard a little more deeply after a drought for about two weeks (while still avoiding overwatering). Continue to water in the early morning hours before 10 a.m. You'll also want to invest in some high-quality fertilizer to get more nutrients to your roots and help them grow back stronger and quicker. Look up your grass and soil type, or do a soil test, to see what type of fertilizer you need.
