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).

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. Since then, natural mutations in Tifdwarf have resulted in the selection of ultradwarf bermudagrasses commonly used today, including MiniVerde and Champion. Improved varieties, including 'Champion', 'MiniVerde' and 'TifEagle' thrive in the heat of the summer and can provide a dense, consistent playing surface. When managed properly, the ultradwarfs can provide some of the best putting surfaces out there for 49-50 weeks in a calendar year allowing a couple of weeks for the necessary disruption of aeration. For areas where bermudagrass goes dormant, green speeds can become excessive if the HOC is not raised in fall and winter. Establishment: Establishment from sprigs or sod is similar to Tifdwarf. Walk behind mowers are preferred over triplex mowers.
