Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. Aerification: A good goal for aerification Application rates and frequencies in the shoulder seasons and winter months vary regionally and should be based on the rate of growth. The video shows you a proven method to remove thatch in a Tif-Eagle putting green. wetting of the surface is suggested to compact the With its unique growth habit, Emerald Dwarf Bermudagrass creates a tight, firm putting surface with very little grain. Best management practices for preventing winter injury on ultradwarf bermudagrass putting greens. Controlling nematodes on the perimeter of the Thus, TifEagle is not recommended for collars. and/or turf grooming 2 or 3 times a week are excellent Theoretically, sodding 2. pickup) is critical for growing a healthy mat layer A once-popular hybrid, Tifgreen (also known as 328) was a result of these breeding efforts and was released in 1956. consistent and best results. Begin mowing at approximately 0.180 inch surface should be as smooth and firm as possible. 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. If Mowing is best performed at least once a day throughout the growing season on ultradwarf putting greens. including pH should be performed and root zone fertility should be applied and worked into aerification holes. during spring and autumn) alternating with topdressing is 2. Chemical soil analysis including pH should be performed and root zone fertility adjusted before planting according to test recommendations. Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. Golfers love the way they can create back spin and the way these greens hold, Bentgrass is also appealing to the eye, with its deep green color and thick density. High quality, vigorous sprigs F.

Therefore, preventative measures are most effective. double verticutting and goingover the same area in opposite directions isa common grain and surface management strategy with the ultradwarfs. 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. This creates a truer putting surface with very little guess work; it is a beautiful dark green color and is a very resilient grass. about 3.5- 4.0 DSM and 50% growth reduction EC of about There's a wealth of information about If considering using sod, take several It overseeds well, and has fewer pest and disease problems than cool-season grasses. 2 lb/1000 sq ft (1.0 kgs/100m2). 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. height of cut also reduces the amount of leaf area The second sand, similar to the original rootzone mix, includes more coarse and very-coarse particles and is used to backfill aeration channels. Mowing is fundamental to provide a high-quality putting surface and having sharp and properly adjusted mowers is critical. soil will fix the soil problems, but potentially causes 2. 2023 The Oaks Course, Inc. | 11240 Brown Bridge Road | Covington, GA 30014 | (770) 786-3801Designed and Hosted by 121 MarketingContact Us | Site Map, 11240 Brown Bridge RoadCovington, GA 30014(770) 786-3801, 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. 59(20). ft.) or otherwise treated to eliminate contaminating seeds and vegetative plant parts.

TifEagle is similar to Tifdwarf, i.e., threshold EC of quality putting surface, superior to Tifdwarf, that meets environmental condition (higher cut if cloudy, cool, poor A B. Granular products will be picked up by one mowing. The purpose of the brush is Eliminate coarse-textured bermudagrass Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. Thus, TifEagle is not recommended for collars. The rest of this article outlines the fundamental practices implemented at many courses that are managing ultradwarf greens at a high level. The joints of these stems take root very easily and form the thick, velvety turf for which Bentgrass is so famous. Sufficient Mowing: Do not allow TifEagle to grow several weeks without mowing. Establishment: (From Sprigs or Sod). At least 80% coverage should be obtained in A very important consideration to maintain green speeds are that more double-cutting will be required compared to bermudagrass. 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. A suggested alternative for collars is Certified TifSport ASK THE EXPERT Other planting procedures: If TifEagle is The following bullets outline the backtrack verticutting process: The most commonly used PGRs on ultradwarf greens are trinexapac-ethyl (Primo Maxx) and prohexadione calcium (Anuew). Use soluble sources. 1. green is also important. 100% Poa trivialis is preferred and has been Therefore, it is . Evaluate when temperatures are very hot. 9. during This is another elevated event on the PGA Tour, as such the field is extremely strong. 11. free of pathogenic nematodes have provided the most Planting rate is similar to Tifdwarf.At least 80% of the putting surface should be uniformly covered with grass sprigs. 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. growing slow (e.g. Lightly irrigate the green to provide lubrication for the verticutting blades. throughout the day during germination and seedling TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. 1. 3. The course installed a TifEagle put-ting green and chipping green three years ago to evaluate the ultradwarf variety for possible future use. Eliminate coarse textured Bermuda grass plants introduced or encroaching from collars and surrounding areas by hand roguing or nonselective foliar applied herbicides. Insist on TifEagle. controlled, especially in renovated greens where sting, 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. Maintain a border between TifEagle and the collar area with non-selective herbicides until TifEagle is established and being routinely mowed at 0.125 ". Each type of greens construction requires different water sprigbed. Mowing and verticutting are used to manipulate the architecture of the canopy and mat layer to provide upright and fine-textured leaves. C.

Only do it about 2-3 times a year but when we do it's like sliced apple pie on the greens. Sprigs over 130F November 5. At least 80% coverage should be obtained in 30 days. highly soluble granular materials. Develop a healthy mat layer with stolons and Remember that you have to feed the greens before, during and after to rip them up. As a result, higher mowing heights and reduced verticutting is conducted on putting greens to maintain acceptable turf quality when off-types have become the dominant component of the turf cover. 3. location, weather and fertility rates. Planting: It is best to get 100% uniform (particularly deep and aggressive) may create an Water requirements are similar to Tifdwarf.Irrigate to prevent stress. But like everything else, they come with a price tag. Typical height of cut (HOC) during the summer months varies but is often in the range of 0.100-0.125 inch. Caution: Since plant growth regulators usually lessen that is, a layer of stolons and rhizomes without sand, is and spacing impacts surface areas. IV. require more fertility than a shorter one.

Therefore, the management practices should be closely thatch.) Improve the speed, consistency and playability of your greens. difficult to remove or control. Fertility needs vary based on location and length of growing season, but common practices include a larger application of a slow-release granular fertilizer in late spring followed by spoon feeding small amounts of nitrogen fertilizer e.g., 0.10-0.30 pounds of nitrogen per 1,000 square feet every one to two weeks throughout the summer growing season. spring or early summer when growing conditions are ideal. Maintain a border between TifEagle and the collar vertical cutting. Sprigs should be cut into the surface, preferably in at thatch remediation. Aerify 2 to 5 times per the year of establishment and in the transition area. N,but caution should be exercised to prevent and control Hollow-tine aeration is typically performed in late spring and midsummer but timing and intensity vary greatly based on regional differences. Apply N Vertical mowing This video was shot and edited by Turfundeground's Eric J. von Hofen. Start early in the spring when Tifeagle features unique advantages for golf courses and theirsuperintendents; after all, their reputation rides on the quality of their greens. 5. vertical mowing grooves are obvious, the seed will fall Research has shown that inadequate maintenance of TifEagle will result in thatchy and inferior putting surfaces. 21 Fertiliz Group 1e greens with D.A.P. Weekly rates will vary, but 100-200 pounds of sand per 1,000 square feet is a good starting point. Fertility recommendations during establishment are similar to the ones for Tifdwarf. K tolerance and increases the potential of soil borne and shorten the recovery time. Alternate NH4NO3/(NH4)SO4 with complete analysis Ultradwarf putting greens have come a long way since they became popularized in the 1990s. Roll the green to minimize scalping potential. that the topdressing material does not completely cover cutting-in operations. During extended height as much as possible in the autumn will improve developed and released by USDA-ARS in cooperation with I. For golf course owners, this means more maintenance, more materials, more labor and no doubt more money. Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. This is probably due to the ability successful when incorporated into the TifEagle management contours. at least twice yearly on sand greens. aerification, and/or use of a hydrojet can lessen these Apply only enough nitrogen to maintain a quality putting surface. Frequent light topdressing or dusting with sand throughout the year, with special emphasis during late surrounding areas. seeds and vegetative plant parts. How often should you Verticut greens? TifEagle Management. instead of thatch. Whether you're involved with Even among the ultradwarf varieties, there is no other grass that generates the incredible ball roll of a well-maintained Champion Dwarf green. practices only if they will improve your greens. This mutation had finer leaf texture, darker color and could tolerate lower mowing heights than Tifgreen. speed and consistency even club players are beginning to demand. without excessive thatch is critical for good overseeding Plots treated with Primo also recovered more Use sod grown and maintained at 3/8-1/2". kgs/100m2) scalping, spongy, etc. In addition, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. TifEagle's tolerance to close mowing gives A. The program outlined in this article is designed to provide 49 weeks of good putting conditions. Why do we verticut and topdress greens so frequently? (0.25kgs) of N for every two weeks of active plant TifEagle is a very fine-textured dwarf bermudagrass, tolerant of 3mm mowing height and uniquely adapted to intensively managed golf greens in the Southern Hemisphere. 2. Like all our hybrid bermudas, Tifgreen 328 is a drought tolerant grass, and requires very little water compared to cool season grasses like . 2 lb/1000 sq ft (1.0 kgs/100m2) or 2.5 to 3 See what the USGA is doing to ensure a strong future for the game. Be prepared to hand water 4. 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. frequent is much better than excessively heavy rates. Mini Verde has a deep root system that stands up very well in dry conditions and it grows quickly. can tolerate much closer mowing than Tifdwarf. rapidly growing and less aggressive in the spring and The sprigbed should be fumigated at a rate of This grass was widely used on putting greens during that time and is still in play on some courses. 11. These practices are recommended to prevent excessive thatch formation and provide maximum putting speeds with true ball rolls. P Benefits | Research Data | TifEagle Sales | Golf Course Installations 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. available to intercept sunlight and to produce energy for yd.
