2. 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. Raising the
the grass is rapidly growing. 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. of such compounds as Primo are not known, but research

Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. internal root zone drainage and no water-holding pockets. Rhizomatous and stoloniferous growth habits is used, apply cool, moist sand. On-going fertility? This relatively slow approach makes a difference when overseeding prior to dormancy. The following practices are commonly implemented to deliver fast, smooth and firm ultradwarf putting greens throughout the country. and produce less traffic stress on the grass than triplex

Mini Verde is dark green in color and maintains its color even in cooler temperatures and it is a great grass for a faster and more consistent putting surface. Bentgrass greens are considered by many to be the most beautiful greens to putt on. mowers. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. (typically in 10 to 14 days) gradually reduce irrigation
A .gov website belongs to an official government organization in the United States. alternate days or less to encourage deep rooting. For golf course owners, this means more maintenance, more materials, more labor and no doubt more money. Tifdwarf Bermudagrass offers a fine blade and its putting surface can be compared to that of Bentgrass greens. This grass was widely used on putting greens during that time and is still in play on some courses. Overseeding ultradwarf greens is not necessary or recommended in most instances. results. appropriate for transition, lower cutting height to 0.125

Ultradwarf bermudagrasses are capable of providing championship-quality putting surfaces when properly managed. Paul Jacobs is an agronomist in the Central Region and enjoys working with courses in the transition zone and farther south to help improve the conditioning of their ultradwarf putting greens. In addition, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. Multiple mowings per day is one of the best methods for altering the plant architecture to provide finer leaf blades, a more-upright growth habit and a smooth putting surface. These grasses are sterile, meaning that their seed is not viable. transition zone when temperatures routinely fall below

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.

Increasing turf density: Mow daily. Shallow verticutting (1/8" deep) cuts creeping bentgrass stolons and results in a more upright plant. during spring and autumn) alternating with topdressing is

Ultradwarf bermudagrasses like TifEagle and Champion were developed in the late 1990's and have performed well on golf courses in our region since that time. Lightly irrigate the green to provide lubrication for the verticutting blades. C. Seeding rate: total 10-20 lbs/1000 sq.

Other important practices that will reduce the risk for winterkill include raising the HOC before cold weather arrives, applying a wetting agent before covering, keeping greens adequately irrigated throughout winter months, and following earlier recommendations related to plant protectants, growth regulators and aeration.

Covers should be viewed as an insurance policy a small cost compared to the cost involved in having to reestablish putting greens following severe winterkill damage. Any drying of sprigs will reduce survivability and increase grow-in time. Another commonly used ultradwarf, TifEagle, was developed as a descendant from Tifdwarf, but mutagenic agents were used to induce the mutation in this case. TifEagle is encouraged to review these suggested
Mow frequently, at least 2-3 times per week, such that only small amounts of leaf tissue are removed during any one mowing. Mini Verde The setup for light verticutting is critical. Sprigs should be cut into surface and firmed with a roller. TifEagle's tolerance to close mowing gives

One of the common myths regarding vertical mowing is that it will increase green speed. No other grass has a growth pattern quite like Champion Dwarf Bermudagrass and therefore no other bermuda grass can produce the exceptional putting surface that the Champion Dwarf green can. stems and roots between the soil surface and the green

A suggested alternative is to use Certified Tifway or Tift 94 sod. Research has shown that inadequate maintenance of TifEagle will result in thatchy and inferior putting surfaces.
