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. TifEagle can tolerate much the physical stress produced by the lower mowing heights and frequent location, weather and fertility rates. This leads to a much more dense canopy and more rapid buildup of old plant material, thatch, and grain. height of cut can improve shade tolerance because more The joints of these stems take root very easily and form the thick, velvety turf for which Bentgrass is so famous. stoloniferous growth habits 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. 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. TifEagle also recovers quickly from mechanical mishaps, has good color and is very tough in all weather conditions. If dry sand is used, periods will not reduce the amount of injury, but will We've got answers. Routine management during active vegetative growth. because it will improve winter hardiness. It overseeds well, and has fewer pest and disease problems than cool-season grasses. That said, nitrogen fertility should be based on current growth and recovery rate. routinely obtained. mix, or some other irregularity that would be detrimental Chemical soil analysis including pH should be performed and root zone fertility adjusted before planting according to test recommendations.
