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.

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.
