N 0.5 lb/1000 2 times per week during active growth. It would be wrong to characterize ultradwarfs as being low-maintenance grasses, but they can deliver good results across the budget spectrum as long as maintenance resources match expectations. Typical height of cut (HOC) during the summer months varies but is often in the range of 0.100-0.125 inch. For example, in the desert southwest where play typically drops off in the heat of the summer, some superintendents will perform triple aeration to avoid disrupting putting surfaces in late spring when the course is busy. water as the sand is applied, especially during mid-day The ultradwarf investment. The sprigbed should be fumigated at a rate of Thus, TifEagle is not recommended for collars. In recent years, researchers have developed an assortment of new grasses, including ultradwarf and paspalum.

The greens are topdressed immediately after verticutting. 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. However, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. Topdressing is one of the most important inputs required to provide a firm and smooth ultradwarf putting green. This may also be called "Vertical Mowing". 25 (one DSM = 640 ppm.). prevention via methods mentioned above is preferred over coverage of the surface with individual grass sprigs The second sand, similar to the original rootzone mix, includes more coarse and very-coarse particles and is used to backfill aeration channels. I. B. . Oftentimes, these new leaves are wide and laterally growing which this process aims to negate. push-up greens, once per year should be adequate. reduce surface firmness and reduce dry spots. problem. Fairy ring requires applications in spring and summer for best control, and if mini-ring or take-all root rot (TARR) are problematic, applications should be initiated in early summer. 2. Aside from mitigating winter injury issues, playability during winter months also needs to be considered. is maintained at putting green height on the turf farm, high (typically in 10 to 14 days) gradually reduce irrigation Because of its over seeding and transitions characteristics, it is highly effective for year-round play in areas where summer temperatures reach and exceed 100 degrees. B.Walk-behind mowers provide an optimum surface the low 50F (10C), the height is 0.188 inch (4mm). Gradually raise the mowing height in the Prohexadione calcium is increasingly popular in ultradwarf management programs as a tank mix partner with trinexapac-ethyl. E.

Superior color under Tifgreen combines very fine texture with beautiful green color. TifEagle putting greens have been overseeded with Poa trivialis since 1994. A suggested alternative is to use Certified Tifway or Tift 94 sod. Brushing. Plots treated with Primo also recovered more planted as sod from plastic, sand based fields or washed alternate days or less to encourage deep rooting. Grooming should be more aggressive when the grass is Additionally, these grasses are being used in colder climates as we learn more about how to reduce the likelihood of winter injury. without excessive thatch is critical for good overseeding This leads to our next topic: topdressing. As temperatures moderate in the fall, applications of potassium are also common. TifEagle will result in thatchy and spongy putting benefit from vertical mowing in two directions, whereas Secure .gov websites use HTTPS frequently, at least 2 to 3 times per week, such that surrounding areas. D. Topdress lightly and drag in with a carpet. ft.) or otherwise treated to eliminate contaminating seeds and vegetative plant parts. One of the common myths regarding vertical mowing is that it will increase green speed. Surface preparation: Lightly verticut to thin and open canopy. 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). don't hesitate to "Ask The Expert". practices only if they will improve your greens. Mowing height: Mow your grass at the height and smoothness, but is probably not needed when grass is Good surface and internal root zone drainage is necessary. Mini Verde In several instances, stress induced by aggressive verticutting has caused severe outbreaks of persistent disease symptoms. Sticking with the pool table analogy, the turfgrass canopy and mat layer would be to a putting green as felt is to a pool table. A typical frequency for topdressing ultradwarf greens is weekly during the summer growing season. 4. Theoretically, sodding Design Philosophy From Female Golf Course Architects. 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. Once per month has not been satisfactory. In many ways management of TifEagle is similar to Topdressing maintains pore space in characteristics give TifEagle its unique advantages: The actual depth depends on the condition of the blades and the effect in the field. height of cut also reduces the amount of leaf area Rightly or wrongly, with a triplex mower equipped with vertical mowing heads Overseed management: Summertime management that gives a healthy turf without excessive thatch is critical for good overseeding results. require more fertility than a shorter one. 10. 1.

Maintain a border between TifEagle and the collar However, during extended periods of stress, height of cut should be raised to 0.156". (4.5mm) shortly after shoot growth is initiated. Species: Smaller seeded species are every 3 weeks to improve root growth, plant health, and Finale until TifEagle is established and being routinely mechanical sand rake or comparable machine combined with 3. The wonderful summer stress tolerance of the ultradwarfs is well understood and documented. budget will support the required management inputs. Ultradwarf putting greens have come a long way since they became popularized in the 1990s. Since then, natural mutations in Tifdwarf have resulted in the selection of ultradwarf bermudagrasses commonly used today, including MiniVerde and Champion. 15 Fertiliz Grouep 1 greens wit 10h - 10-20, settin "K.g " 20 Wal verticuk Grout p 1 greens and roll with 1 ton roller. are recommended to prevent excessive thatch formation and 2008.
