Abstract/Contents:"Concern has been expressed regarding the ability to establish a winter overseeding of cool-season turfgrasses into the new, very-high density, vertical-dwarf bermudagrass (Cynodon spp.) cultivars. Comparisons were made in three different warm-season environments includeing; hot-dry desert; hot-humid inland, and warm-humid coastal areas, using the cultivar Champion. The experimental sites were maintained at a 3.2 mm height of cut, with 3 replications for each of the 6 seed mixtures, 2 preplant methods, and 3 seeding rates. Monthly assessments made following winter overseeding included a visual estimate of percent seedling coverage, and a visual estimate of turfgrass quality. Shoot densities of the overseeded turfgrasses were counted, and the mat and root depths of the Cynodon were measured. Results indicate: (a) the best timing for overseeding should be determined by soil temperature rather than a calendar date; (b) the optimum cultivar mixtures and seeding rates were: 4 kg of Poa trivial and 1 kg of Agrostis stolonifera, followed in 30 days by 1 kg of P. trivialis; 5 kg of P. trivialis and 1 kg of A. stolonifera; and 4 kg of P. trivialis, and (d) spring transition was successful using timely cultural methods involving lowering the cutting height, increasing the nitrogen rate, and weekly vertical cutting."
