Species: Smaller seeded species are Mowing height should be lowered to 0.250" within this period. Increasing turf density: Mow daily. growth. Due to increased traffic, sprig Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. Severe verticutting and/or aerifying will result Begin mowing at approximately 0.180 inch 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. Other planting procedures.If TifEagle is planted as sod from plastic, sand based fields or washed sod, greens should be aerified with core removal after sod is rooted to minimize root zone layering. Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. 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. kgs./100m2)/growing month. of such compounds as Primo are not known, but research The goal is to manage lateral growth and promote a fine-textured plant with upright growth not to harvest a significant amount of material. Once per month has not been satisfactory. Released by internationally recognized USDA/ARS plant geneticist Dr. TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. Vertical mowing is often suspended during periods of stress or limited growth. year (during early and late summer months) using up to Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. Planting rate is similar to Tifdwarf.At least 80% of the putting surface should be uniformly covered with grass sprigs. A preventative fungicide application A. III. Controlling nematodes on the perimeter of the Sufficient topdressing material should be applied and worked in to backfill aerification holes. 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.. Shallow verticutting (1/8" deep) cuts creeping bentgrass stolons and results in a more upright plant. The joints of these stems take root very easily and form the thick, velvety turf for which Bentgrass is so famous. Vegetative Growth. 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. micro-environments, shade, wind movements, etc. November 5. 10.

Pest management requirements: Similar to managing this mat layer will depend on season, weather, Thatch prevention: A key concept is THATCH practices. Likewise, putting greens should be verticut and . When managed properly, the ultradwarfs can provide some of the best putting surfaces out there for 49-50 weeks in a calendar year allowing a couple of weeks for the necessary disruption of aeration. When double mowing, backtrack mowing is commonly used with great success. 9. 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. Fertility recommendations during establishment: grass (fertility, disease, nematodes, etc), A. TifEagle Once the greens are killed, they are scalped and verticut twice, removing the top two to four inches of the green. 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. is maintained at putting green height on the turf farm, Suggested alternatives are micro or mini particles or The last option would be to raise the height. General Management Guidelines During Active the grass is rapidly growing. TifEagle has proven to be a premier putting surface with a number of Keene says that the differences in manage-ment practices between Tifdwarf and TifEagle makes for extra work in having different mowing and verticutting heights and schedules. Periodic application alternate days or less to encourage deep rooting. The following bullets outline the backtrack verticutting process: Mow the putting green. "Sunday outperformed TifEagle in cool season color, height of cut, and green speeds and has two-thirds more root mass," said Easter. fall when growth has slowed down.
