Abstract/Contents:"The first of the new, ultra high-density, vertical-dwarf Cynodon dactylon x C. transvaalensis cultivars, became available for use in 1995. There was some concern about the ability to germinate and establish a winter overseeding of cool-season turfgrasses on these putting greens due to the very high shoot density. To address this issue, comparisons were made in three different warm-season environments. The turfs were maintained at a 3.2 mm cutting height, with three replications. Turfgrass assessments included: seedling emergence, surface coverage, and turf quality. Shoot densities of the overseeded turfgrasses were counted and the mat and root lengths of the C. dactylon x C. transvaalensis were measured. Results indicate: (a) winter overseeding can be successfully accomplished into the high-density Cynodon cultivars such as Champion, if appropriate procedures are followed that include the use of small seeded species such as Poa trivialis and Agrostis stolonifera, (b) the top ranked cool-season grass mixtures and seeding rates were: a mixture with 4 kg 100 m-2 of Poa trivialis and 1 kg 100 m-2 of Agrostis stolonifera, followed in 30 days by 1 kg 100 m-2 of P. trivialis; a mixture with 5 kg 100 m-2 of P. trivialis and 1 kg 100 m-2 of A. stolonifera; and P. trivialis at 4 kg 100 m-2; and (c) the higher seeding rates such as for monostands of P. trivialis at 8 kg 100 m-2 and A. stolonifera at 2 kg 100 m-2 resulted in a substantial reduction in rooting of the hybrid Cynodon, (d) the best timing for winter overseeding should be determined by soil temperature rather than a calendar date; (e) spring transition to C. dactylon x C. transvaalensis was successfully completed by cultural methods; and (f) it may not be necessary to winter overseed Champion in certain warmer U.S. locations."
