Buffalograss, St. Augustine grass, centipedegrass and zoysiagrass are drought-resistant grass varieties. Bermuda grass and bahia grass can also grow with very little water. Additionally, mowing the grasses when at a certain height aids in improving their drought tolerance.
Bufalograss, which thrives in full sun, has a low degree of tolerance to traffic and needs very little water to grow. The grass is established using plugs and tolerates mowing only when at least 5 inches high. Legacy is a popular example of a bufalograss cultivar. St. Augustine grass can only put up with average traffic and may be vulnerable to diseases in winter if exposed to too much water. The best cultivar for drought resistance is floratam, and it can perform better under shade.
Zoysiagrass, such as empire grass, has good tolerance capacity against traffic, but unlike buffalo and St. Augustine grasses, it takes a long period to grow. Although centipedegrass takes a long time to grow, it is easy to maintain and persistent even under acidic conditions.
Bahia grass, which can grow in relatively infertile soil, has an extensive root system that makes it adaptable to drought, and it has a high degree of tolerance to diseases, insects and traffic. The grass does not grow well under shaded conditions. Some Bermuda grass cultivars, such as common Bermuda, have the ability to recover quickly after watering and require frequent mowing.
