When choosing a grass seed, it is important to know the soil conditions of the growing site. Poor soil properties can lead to thin, patchy growth. Sandy soil can support some, but not all types of grasses.
Grass seed requires well-drained soils to grow, and the amount of sand in the soil is key for good drainage. Sandy loam soils are best, with 60- to 70-percent sand. Soils that have a higher percentage of sand may require amending or consideration of a grass species that does well in sandy soil.
Grasses that grow well in sandy soil tend to be drought tolerant and are used for lawn plantings in the Southern part of the United States. Some varieties that do well in sandy soil are Bermuda, St. Augustine and Smooth Bromegrass.
Have a soil test preformed to determine the soil conditions of the planting site. Soil testing kits can be obtained through state cooperative extension offices, agribusinesses and regional agronomists. Knowing the soil type will help to make better decisions in future lawn care.
