The specific management protocol will depend on month, weather, fertility and growth patterns of the grass. aeration. before overseeding. While the ultradwarfs were first used as an alternative to bentgrass because of their reliability in summer, many courses have proven that these grasses can provide championship-quality conditions throughout the year when properly managed. There is no one-size-fits all program for ultradwarf management, but these practices are fundamental to produce high-quality surfaces for 49 weeks of the year allowing a few weeks for the necessary disruption of aeration. within the layer, and poor

Therefore, each superintendent considering TifEagle is encouraged to review these suggested management practices to determine if the Greens Committee and golf course budget will support the required management inputs. A. General Considerations:

Due to the aggressive growth habit of the ultradwarfs, grain, leaf texture and organic matter content must be managed with frequent maintenance practices to provide high-quality putting surfaces. C. Seeding rate: total 6-12 lbs./1000 sq. This practice also reduces the risk of winter injury, but on non-overseeded ultradwarf greens it is necessary to prevent speeds from becoming excessive during the winter months.

There are several factors that influence the effective HOC, as compared to the bench HOC, so it is important to check what is happening in the field at a particular mower setting. Ultradwarfs can also deliver championship-quality conditions throughout much of the year if the resources are available for consistent surface management throughout the growing season. However, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. In the past, a lot of golf coursesused Bentgrass. TifEagle putting greens have been overseeded with Poa trivialis since 1994. surfaces at cutting heights of 0.125 inch (3.2mm).

Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. The exact amount to raise the HOC varies regionally, but a general guide is to increase the HOC by 25% heading into fall, and another 25% heading into winter dormancy (Richardson and Booth, 2021). Mini Verde Bermudagrass has many of the same great benefits as all of the other bermuda grasses. Use
