When balancing the temperature of water flow, try turning the water flow down instead of up. If the water is too hot or too cold, turn the offender down rather than increasing water flow. Water lawns only when grass shows need for irrigation. Generally, lawns need watering only every five to seven days in summer and every 10 to 14 days in winter. When grass blades begin to fold in half lengthwise, or fail to spring back up when stepped upon, or turn a grayish color, it is time to water.
Water lawns deeply, but less frequently.
Put about one inch of water on the lawn each time you irrigate. More water is wasteful and less water does not promote deep root growth. Some types just keep the sprinklers from operating in the rain. Others actually monitor soil moisture content and allow the system to water only when needed. They include reducing grass areas, grouping plants by similar water needs, mulching, efficient irrigation, and using drought-resistant native plants.
