During periods of rapid growth, do not However, as a result of its distinct genetic background, turf density and ability to tolerate extremely low heights of cut, several suggested management practices are specific to TifEagle. 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. Evaluate In order to provide a good putting surface this dense canopy needs to be thinned out, removing old plant material, and encouraging a more upright growth habit. Grooming should be more aggressive when the grass is Apply N Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. is less 'forgiving' if you neglect optimum management That said, if the goal is to overcome weaknesses in infrastructure or to simply provide healthy, dense turf then some savings may be realized by converting from bentgrass to an ultradwarf (Hartwiger and OBrien, 2008). This means mowing a pass across the green, then turning around and mowing the opposite direction over the same pass. Whether youre considering a conversion or trying to stay up to date on the latest trends in ultradwarf management, this article is for you. vertical mowing is used in preparation, leave plenty of Mowing height should be gradually lowered to 0.140 inch Use only freshly harvested, cool Sufficient topdressing material should be applied and worked in to backfill aerification holes.

Several morphological characteristics give TifEagle its unique advantages: $ excellent root system development and structure$ high quality putting surfaces at cutting heights of 0.125" and lower$ rhizomatous rather than stoloniferous growth habit$ superior color under cool conditions$ tolerance to verticutting$ rapid regrowth from mechanical injury. Double mowing will add speed On high CEC or Items such as mowing and rolling frequency, verticutting, clipping yield, topdressing rates and PGR applications all tell a story when the data is collected daily and analyzed at the end of the week, month or year. Severe verticutting and/or aerifying will result water as the sand is applied, especially during mid-day Tifgreen combines very fine texture with beautiful green color. TifEagle's tolerance to close mowing gives Raising the mowing rapidly growing and less aggressive in the spring and The type of sand used varies, but many have implemented a two-sand system where a sand with fewer coarse particles and no very-coarse particles (> 1 mm) is used for routine topdressing. in 1996 at golf course locations from Florida to the desert Southwest, After rooting (typically in 10 to 14 days) gradually reduce irrigation frequency to once or twice per day while maintaining a moist root zone. Consult the Each golf course will be different and each green on the yds/1000 sq.

We now have a much better understanding of the maintenance practices that will provide good putting surfaces for a majority of the year. It for one fills in any inconsistencies in the putting surface, adds firmness, reduces the impact of grain, reduces algae, and most importantly dilutes the soil profile, leading to better water infiltration, more oxygen for roots, and disease prevention. In addition, verticutting removes removes excessive tissue. Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. characteristics give TifEagle its unique advantages: Why do we verticut and topdress greens so frequently? D. Soil test (for P, K, Ca, Mg and lime needs) aerification and other routine practices for a TifEagle Mow This aids in incorporation and reduces the amount of large particles that remain on the surface.

Sprigs should be cut into surface and firmed with a roller. the development of a severe thatch layer that will be II. develop above the soil, making them more susceptible to 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. much of a superintendent's reputation rides on the quality of his or The goal is to be light and frequent so that there is no significant disruption to playability.". Likewise, putting greens should be verticut and . The first pass should be made in the most aggressive direction (down grain) and the second in the opposite direction, but on the same pass. However, regular roguing of all bermudagrass greens is and faster greens speeds than TifEagle not treated with Light and frequent topdressing accomplishes many things in ultradwarf putting green managment. including pH should be performed and root zone fertility a uniform and healthy turf.

Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. free of pathogenic nematodes have provided the most This will also improve root growth, Establishment: (From Sprigs or Sod). Trinexapac-ethyl has been used for many years on ultradwarf greens to provide growth suppression and improve shade tolerance. A very important consideration to maintain green speeds are that more double-cutting will be required compared to bermudagrass. Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. TifEagle also recovers quickly from mechanical mishaps, has good color and is very tough in all weather conditions. Theoretically, sodding A suggested alternative for collars is Certified TifSport double verticutting and goingover the same area in opposite directions isa common grain and surface management strategy with the ultradwarfs. or aerify with 1/4 inch (6mm) quadra-tines or star-tines is maintained at putting green height on the turf farm, stems and roots between the soil surface and the green frequency to twice per day, then once per day, then have been overseeded with Poa trivialis since 1994. Hydrojet TifEagle will produce higher quality putting surfaces than Tifdwarf, but also requires more intensive management. only small amounts of leaf tissue are removed during any That said, nitrogen fertility should be based on current growth and recovery rate. In many ways management of TifEagle is similar to B. The USGA promotes and conserves the true spirit of the game of golf as embodied in its ancient and honorable traditions. Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties.

It will be extremely 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. Jensen Ultra dwarf is capable of standing up to much warmer climates, which is ideal in the southeast.
