Do different varieties of turfgrasses use different amounts of water?
Many studies have been conducted on water use of turfgrasses. Most of these studies are conducted under “well-watered” conditions (i.e., no stress due to lack of water) and should not be confused with drought studies where water is withheld and physiological responses of grasses are studied. All turfgrasses need water to sustain good quality (dense, uniform, green), whether it comes from rainfall or supplemental irrigation. Drought-tolerant grasses will go into dormancy during dry periods, growing more slowly or turning brown until conditions are favorable for growth. When enough soil moisture returns, these grasses can usually recover from drought-induced dormancy rather than dying. For example, bahiagrass is drought-tolerant, but if it is not supplied with adequate water, the drought response of this grass will result in dormancy and a “dead” appearance. Much of the literature seems to indicate that there may be differences in water use between different warm-season grasses.
