How to Grow a Lawn in Sandy Soil


Grass thrives best in a soil that is loamy and rich in nutrients. Sandy soil doesn't retain moisture or nutrients well, which can lead to an unhealthy lawn. If you want to grow a lush, thick lawn in sandy soil, it must first be amended with organic material like compost and peat. These substances are tilled into the existing soil and help the soil retain the needed moisture and nutrients for your grass. This can be a labor intensive project but it is well worth the effort in the end.

Step 1

Mix 6 inches of equal parts peat and compost into your existing soil. Use a rototiller to mix it in well.

Step 2

Rake the loamy soil smooth with your garden rake and firm it up by rolling it with a water-filled lawn roller.

Step 3

Read the application instructions on the grass seed bag and set the broadcast spreader to the indicated setting. Fill it up and walk back and forth across the entire lawn to spread the seed.

Step 4

Ensure the grass seed makes great contact with the soil by raking the soil to bury the seeds to a depth of 1/4-inch.

Step 5

Water your lawn with sprinklers to keep the soil moist at all times. Your lawn probably will need two to three waterings per day at a duration of five to 15 minutes for each cycle.

Step 6

Reduce watering frequency once germination occurs, which is usually seven to 14 days after seeding. Water once per day for a duration of 15 to 20 minutes.

Step 7

Mow your grass to a height of 2 inches once it reaches 3 inches tall. Keep mowing every four to seven days and gradually raise the height to 2 1/2 to 3 inches. After the first mowing, resume your regular irrigation schedule.

Tips and Warnings

  • Don't let water pond on the surface of the soil when watering. If the soil is saturated, the seeds will likely rot. Adjust the irrigation schedule to prevent this.
