Planting grass seeds in sand can be a real challenge because the only thing sand has going for it in terms of planting is good drainage. Sand is notoriously devoid of nutrients and also isn't firm enough to give grass roots a secure footing. Fortunately, a little preparation can make even the sandiest patch of ground into a lush, green lawn.
Rake the sandy patch of ground and get rid of all debris, such as rocks, roots and dead plants. Rake as deep as you can; the optimum depth for properly cultivating your growing area is 6 inches. If you run into clay, use the shovel to break it up so you can achieve your 6-inch depth.
Dump in peat moss and organic matter and blend thoroughly with the sand. The end result should be a layer of cultivated soil, 6 inches deep, that is no more than 50 percent sand.
Water thoroughly and let sit overnight.
Add fertlizer, but use it sparingly–no more than 2 or 3 pounds for every 100 square feet. Too much fertilizer can burn the grass seedlings.
Water again, and let sit overnight.
Rake the surface and plant the grass seed, using about 5 pounds of grass seed for every 1,000 square feet of ground. Use a seeder to ensure proper seed distribution.
Rake again to get the seeds settled into the soil and then roll with a weighted roller to secure the seeds.
Water lightly with a very gentle stream or even mist. You don't want to wash the newly planted grass seeds away.
