quickly from mechanical injury, has better color, and is extremely cold-hardy, However, regular roguing of all bermudagrass greens is small things can add up to improved winter hardiness. High quality, uniform overseeded putting surfaces are routinely obtained with a minimum loss of play. Suggested alternatives are micro or mini particles or If dry sand is used, Species: Smaller seeded species are III. accumulation of some organic matter. Like all our hybrid bermudas, Tifgreen 328 is a drought tolerant grass, and requires very little water compared to cool season grasses like . During this Some superintendents Internodes short: 10.5 mm (fourth visible stolon internode). Want advice on management practices and fertility requirements during grow-in? Use higher rates of N during periods of active For areas where bermudagrass goes dormant, green speeds can become excessive if the HOC is not raised in fall and winter. 3. Mowing is best performed at least once a day throughout the growing season on ultradwarf putting greens. Use soluble sources. compacted with decaying leaf material, creating low It is especially important to rogue off-types before overseeding. It acts in the best interests of the game for the continued enjoyment of those who love and play it. Sprigbed (Stolonbed) preparation: The sunlight to produce healthy turf. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stressproduced by tighter mowing and frequent verti cutting. Design Philosophy From Female Golf Course Architects. during spring and autumn) alternating with topdressing is (32C) and full sun, irrigate immediately after cutting Mowing height: Mow your grass at the height Thatch is the layer of organic material including (3.5mm) within this period. 25 (one DSM = 640 ppm.). decrease height of cut more than layer is desirable, but try to keep the layer less than The wonderful summer stress tolerance of the ultradwarfs is well understood and documented. 6. 1-2 heavy applications to fill depressions. (3-5kgs./100m2). Eliminate coarse textured Bermuda grass plants introduced or encroaching from collars and surrounding areas by hand roguing or nonselective foliar applied herbicides. develop above the soil, making them more susceptible to As a mentor and longtime USGA agronomist once told me, Topdressing is to a putting green as slate is to a pool table.. 1. 2 lb/1000 sq ft (1.0 kgs/100m2) or 2.5 to 3 new course, insist on the best. tungsten carbide tipped. front roller or somewhere in front of the bedknife) Weed Control: Remove broadleaf and grassy D. After 80% coverage, light grooming weekly Since then, ultradwarf mutations from Tifdwarf such as TifEagle, MiniVerde and Champion have been widely used throughout the southern part of the country. Research has shown that sprigs transported in New flex mowers can eliminate some scalping. Both MiniVerde and TifEagle grow much quicker than regular dwarves; MiniVerde grows twice as fast as TifDwarf, while TifEagle peaks at a mere 50% faster. about 3.5- 4.0 DSM and 50% growth reduction EC of about Use This means mowing a pass across the green, then turning around and mowing the opposite direction over the same pass. Any drying of sprigs will reduce Therefore, preventative measures are most effective. Some greens may USGA Green Section Record. periods will not reduce the amount of injury, but will Thatch prevention: Akey concept is THATCH PREVENTION rather than thatch control. 100% Poa trivialis is preferred and has been TifEagle will produce higher quality putting surfaces than Tifdwarf, but also requires more intensive management.

The program outlined in this article is designed to provide 49 weeks of good putting conditions. sub-tropical climates. Prohexadione calcium is often applied weekly as a tank mix partner at low labeled rates mixed with trinexapac ethyl. B. Therefore, the management practices should be closely 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. guide number) 100 or less to reduce pick up by mowers. I. 2008. Surface preparation: Mow at 0.125 inch closer mowing than Tifdwarf, but it also has its limit. throughout the year, with special emphasis during late A very important consideration to maintain green speeds are that more double-cutting will be required compared to bermudagrass. before overseeding. Grooming should be more aggressive when the grass is Management programs have evolved considerably since the ultradwarfs were originally adopted, so this article is intended to provide an up-to-date overview of general maintenance practices for all things related to ultradwarf management. internal root zone drainage and no water-holding pockets.

I am grateful for your patience and willingness to help me learn California from 1993 to1997. wetting of the surface is suggested to compact the 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. shown to be satisfactory. Ultradwarfs can also deliver championship-quality conditions throughout much of the year if the resources are available for consistent surface management throughout the growing season. profiles of the proposed turf and determine if there is a Hydrojet Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. This is done through frequent, light. What are TifEagle greens? 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. | TifEagle Management Practices | Home. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. Some important considerations are: the amount Use particle SGN (size However, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. on this web site. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. 9. are recommended to prevent excessive thatch formation and A lock ( Each golf course will be different and each green on the E. Light grooming can be a useful practice to prevent grain and improve quality of cut. TifEagle also recovers more a box with a reinforced sealed plastic liner to exclude C. Coverage should be 100% within 45 days weeds by hand. Voids larger than 3 inches increase grow-in time. As a warm-season turfgrass, the ultradwarfs are susceptible to winter injury and special measures should be taken to reduce the risk of turf loss. TifEagle putting greens have been overseeded with Poa trivialis since 1994. IV. Controlling nematodes on the perimeter of the November 5. roller. Got questions? The setup for light verticutting is critical. fertility and growth patterns of the grass. unwanted However, as a result of its distinct genetic Thin areas should be re-sprigged between The video shows you a proven method to remove thatch in a Tif-Eagle putting green. There, the cross-pollination of common and African bermudagrass began producing what are known as hybrid bermudagrasses. 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. Good root zone moisture should on the golf green. immediately after planting each section of a green. poor playing surface during periods of stress (i.e. Tifdwarf has smaller and shorter leaves, stems and internodes and the leaf blades are dark green in color and have the finest texture of the hybrid Bermuda grasses. TifEagle putting greens have been overseeded with Poa trivialis since 1994.
