The water requirements for buffalograss are considerably less than other turfgrass species. Excessive irrigation creates weed pressure, increased mowing, and disease susceptibility. In most cases natural precipitation provides adequate moisture for growth, but timely supplemental irrigation will enhance the turf quality.
In periods of extended drought, deep soaking with no less than one inch of irrigation water once a month may become a necessity to prevent drough-induced dormancy. Soak soil before winter if soil is dry.
