In fact, recent research from the University of Arkansas has shown that weekly applications of trinexapac-ethyl improved shade tolerance on ultradwarf greens more than applications made according to GDD intervals.

If a significant amount of material needs to be removed, verticutting is probably not being performed frequently enough. 8. require more fertility than a shorter one. B. Another of the Bermudagrass varieties, Tifeagle has also proven to be a premier putting surface. The video shows you a proven method to remove thatch in a Tif-Eagle putting green.

The data collected from these sites show that TifEagle is capable of producing a premium quality putting surface meeting the highest golfing standards. 2023 United States Golf Association. "Sunday also recovers better from verticutting and aerification, and requires less fungicide." Based on the test results, Easter chose Sunday for Broken Sound's Club Course greens renovation in 2018. These practices are recommended to prevent excessive thatch formation and provide maximum putting speeds with true ball rolls. 0.5 lb/1000sq ft (0.25 kgs N/100m2) 2 times per week
Additionally, these grasses are being used in colder climates as we learn more about how to reduce the likelihood of winter injury. However, one of the major weaknesses of the ultradwarf bermudagrasses is susceptibility to damage or death from cold temperature exposure. Backtrack verticut the green. Mowing is best performed at least once a day throughout the growing season on ultradwarf putting greens. vii ACKNOWLEDGEMENTS I would like to thank Dr. Elizabeth Guertal and the members of my graduate committee for their guidance, support, and cooperation throughout the course of my masters research project.

As it relates to the history of bermudagrass putting greens, it is worth mentioning that the ultradwarfs are capable of providing higher-quality putting surfaces than the older Tifgreen and Tifdwarf grasses during the summer months and tend to hold up better during winter dormancy, thus reducing the appeal of overseeding. Verticutting requirements depend to a large degree on
