Zoysia

Zoysia is a warm-season grass like Bermuda but has greater shade tolerance, making it an option for shaded courses. It’s more resistant to disease than Bentgrass but does not handle drought, as well as Bermuda Grass. Zoysia requires less frequent mowing but benefits from consistent fertilization to maintain its thick and lush appearance. Bermuda Grass, on the other hand, has a firmer, faster surface and quicker recovery, making it a preferred choice in regions where it’s sunny and dry.

Kentucky Bluegrass

Kentucky Bluegrass is a cool-season grass famous in temperate climates due to its lush appearance and adaptability. However, it is prone to diseases like leaf spot and requires consistent irrigation and fertilization. Bermuda Grass thrives in high temperatures, offering resilience against pests and diseases. Its rapid growth provides a firm surface that supports faster play. Kentucky Bluegrass tends to be used more on fairways and roughs, while Bermuda Grass is commonly selected for all areas of the course due to its versatility and resistance to heat.

Environmental Benefits and Drawbacks of Bermuda Grass

Bermuda Grass provides many environmental benefits that make it an attractive choice for golf courses, particularly those in warmer climates. These advantages help create lush and resilient greens and fairways with minimal environmental impact.
