Proper water techniques are often misunderstood. As a general guideline, lawns only need 1″ to 1.5″ inches of water per week. It's best to water 1 to 2 times per week early in the morning to achieve this goal. Watering for a longer period of time less frequently soaking the soil to a 6″ to 8″ depth will promote a deeper root system and improve drought tolerance. Short frequent watering will cause shallow rooting. Shallow rooting will lead to poor drought tolerance and increase disease susceptibility. Its best to water your lawn and landscape plants early in the morning before the sun rises. This will allow time for the water to soak into the soil before evaporation can occur.
