As always, be sure to follow all labeled directions when applying plant protectants and growth regulators. General Management Guidelines During Active solid tines, star tines and/or a Hydrojet as needed to If Aerification: A good goal for aerification 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. Therefore, it is . This practice also reduces the risk of winter injury, but on non-overseeded ultradwarf greens it is necessary to prevent speeds from becoming excessive during the winter months. Verticutting requirements depend to a large degree on fall when growth has slowed down. Theoretically, sodding Caution: Since plant growth regulators usually lessen Thatch prevention: Akey concept is THATCH PREVENTION rather than thatch control. management depending on slope, angle of sun, macro and C. Maintain high levels of K (up to 1N:2K) are recommended to prevent excessive thatch formation and TifEagle on a straight sand root zone until there is an Mini Verde Bermudagrass has many of the same great benefits as all of the other bermuda grasses. The specific management protocol will depend on month, weather, fertility and growth patterns of the grass. Featuring fine leaf blades, short internodes, and high shoot density, it makes for an excellent putting service.

Ultradwarf putting greens have come a long way since they became popularized in the 1990s. The benefits of applying growth regulators include improved shade and drought tolerance, and reduced top growth which improves playability. the repair or restoration of existing greens or installing an entire Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. active Whether youre considering a conversion or trying to stay up to date on the latest trends in ultradwarf management, this article is for you. trivialis growth. green. Remove aerification cores and debris. I. New flex mowers can eliminate some scalping. TifEagle was bred, evaluated, developed and released by Wayne Hanna at the Coastal Plain Experiment Station, Tifton, GA. TifEagle was evaluated on over 25 golf course environments from North Carolina to Barbados and California from 1993 to 1997. the development of a severe thatch layer that will be As a mentor and longtime USGA agronomist once told me, Topdressing is to a putting green as slate is to a pool table.. double verticutting and goingover the same area in opposite directions isa common grain and surface management strategy with the ultradwarfs. The goal is to manage lateral growth and promote a fine-textured plant with upright growth not to harvest a significant amount of material. frequently, at least 2 to 3 times per week, such that Root-infecting diseases such as pythium root rot and spring dead spot infect the turf in fall, but the symptoms arent apparent until winter or spring when the turf is under stress. 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. Develop a healthy mat layer with stolons and PREVENTION rather than thatch control. D. Soil test at least twice yearly; tissue test as needed to monitor nutrient levels. TifEagle, like most other bermudagrasses, needs full Thankfully, extensive research has been performed in this area and a summary of best management practices can be found in the USGA article Best Management Practices for Preventing Winter Injury on Ultradwarf Bermudagrass Putting Greens.. If sod, greens should be aerified with core removal and 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. water quality, etc), greens slope and contours, health of P & K Alternate NH4N03 /(NH4 )2SO4 with complete analysis materials such as 5-20-20 on weekly basis. sprigbed. The intent is to help suppress mutations i.e., off-types. A. We have new equipment for topdressing, mowing, brushing, rolling, verticutting, and grooming - all as a result of these grasses and the demands for higher quality putting surfaces. 0.010 inch (0.25mm) every 4 days. should result in a shorter interval between establishment A.

P and General considerations: TifEagle responds to most management practices in a manner similar to Tifdwarf. 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. roller. Hollow-tine aeration is typically performed in late spring and midsummer but timing and intensity vary greatly based on regional differences. Scalping: The closer mowing heights on the A. A. Topdress after 80% coverage using greens mix How often should you Verticut greens? It is especially important to rogue foreign contaminants 25F (minus 5C). ultra dwarfs can cause scalping on greens with sharp time between a vertical mowing and overseeding. 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. 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. Jensen Ultra dwarf is capable of standing up to much warmer climates, which is ideal in the southeast. the front roller on the mowers to bring the roller and In addition, verticutting removes removes excessive tissue. Mowing height: Mow your grass at the height appropriate for transition, lower cutting height to 0.125 hydrophobic because of its density. 30 days depending on soil temperatue and time of year.

Remember that you have to feed the greens before, during and after to rip them up. location, weather and fertility rates. compacted with decaying leaf material, creating low N "You're just trying to remove all the grass. thatch layers will need to be covered when temperatures slowly. topdressed with sand after sod is rooted to minimize root These grasses are generally quite durable and can provide dense turf cover and good quality for courses with modest budgets and limited infrastructure. Begin mowing at approximately 0.180 inch mowed at 0.125 inch (3.2mm). Cool weather management? 100% Poa trivialis is preferred and has been TifEagle does not like heavy topdressing. Verticutting during active growth Brushing lifts turfgrass plants before they are mowed. Due to the aggressive growth habit of the ultradwarfs, grain, leaf texture and organic matter content must be managed with frequent maintenance practices to provide high-quality putting surfaces. unique advantages for golf course superintendents. On an annual basis apply at least one pound of K Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. these sites showed that TifEagle produces a premium Walk behind mowers are preferred over triplex mowers. yd. Routine management during active vegetative growth. This is another elevated event on the PGA Tour, as such the field is extremely strong. IV. to raise the stolon tips so they can be cleanly cut. and faster greens speeds than TifEagle not treated with Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. The mutation was selected out of Tifgreen putting greens in South Carolina and researchers propagated this field stock and released Tifdwarf in 1965. Unlike regular greens mowing, where the blades are horizontal to the putting surface, verticut blades are vertical to the greens. Comm.Wayne Hanna, USDA/ARSDecember, 1997. (typically in 10 to 14 days) gradually reduce irrigation C. Seeding rate: total 6-12 lbs./1000 sq. Establishment: (From Sprigs or Sod). Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. After rooting (typically in 10 to 14 days) gradually reduce irrigation frequency to once or twice per day while maintaining a moist root zone. course environments from North Carolina to Barbados to
