Which of the following is a major warm-season grass?

Zoysia grass is indeed classified as a major warm-season grass. This type of grass thrives in the warmer months, typically growing best when temperatures are between 80°F and 95°F. Its growth pattern aligns with the general characteristics of warm-season grasses, which are well-adapted to resist heat and drought conditions, making them particularly suitable for regions with warmer climates such as Oklahoma.

In contrast, the other options represent cool-season grasses, which have peak growth periods in the cooler temperatures of spring and fall. Tall fescue and Kentucky bluegrass are both popular cool-season grasses that prefer cooler, more temperate environments and do not perform as well in extreme heat. Creeping bentgrass, often used on golf courses for greens, also falls into the category of cool-season grasses, showing optimal growth in cooler weather. The choice of Zoysia grass reflects an understanding of grass types and their adaptability to climate, which is essential for effective turf management in warmer regions.
