In turf, daily watering or watering on alternate days can be one of the most harmful of garden practices. Root systems Light, frequent watering causes the turf to develop shallow root systems. Shallow roots have a limited area to obtain the nutrients they need and are more prone to drought stress. Deep, infrequent watering stimulate roots to grow deep in search of water as the soil dries out. Deep-rooted turf is stronger, healthier turf.
Timing is important The timing of watering is very important.
Water turf separately from shrubs, ground covers and other beds. Avoid watering in windy conditions which cause water to drift. A rainfall of 1 inch or greater will substitute for a watering. Do not water your turf again until it shows signs of stress. Signs may include curling of leaf blades, turf turning gray-green in color, or foot prints remaining on the turf after it has been walked on.
