County Agent, Orleans Parish LSU AgCenter. South Louisiana continues under a severe to extreme drought situation. This method encourages a deep, extensive root system. Light, shallow watering results in very shallow root development that will quickly result in plant wilting under stress. Provide adequate potassium fertilization.
Potassium is the key fertilizer element involved in internal water movement.
Provide adequate, not excessive nitrogen fertilization. Don't be aggressive with nitrogen fertilization levels if you don't have good irrigation available. Too much nitrogen can accelerate the problems seen during dry conditions. Raise the mowing height of turfgrass to a maximum level that still allows for desirable appearance and performance. If possible, raise mowing levels prior to a predicted drought.
