Objectives were to study effects of fertility level and cutting height on underground growth of various Kentucky bluegrasses during various seasons and develop a technique for measuring underground growth without disturbing the cultivars and genotypes. Most root growth occurred in late winter and spring, and cultivars and genotypes with high amounts of roots in late spring tend to have a better chance of survival with less maintenance during the summer. Fylking produced more roots in spring and survived under low cutting height better than other cultivars and genotypes. BA6124 produced more roots in summer than any other cultivar and genotype. No cultivar and genotype had the largest underground growth throughout all parameters studied; therefore, blending is recommended to create a desirable bluegrass turf.
