Abstract: The clonal growth of carpet grass (Axonopus compressus) under periodic defoliations was studied in this randomized block experiment. There were significant, or very significant, differences between periodic defoliations and the optimum growth of carpet grass when the leaves were moderately pruned. Too high or low frequently of leaf cutting (D10 or D60) inhibited the normal growth of carpet grass and led to lower quality turf. However, moderate defoliation could contribute to clonal growth of carpet grasses and improve their ornamental value.
