Timing of watering is crucial. Water early in the morning and complete before 9 AM.
Night watering is not recommended, as it can cause fungus to develop. More lawns are harmed by too much water than not enough. Over watering causes nutrients to be flushed away, resulting in higher fertilizer requirements. Over watering also displaces oxygen from the soil, which leads to shallow roots and a lawn that is disease prone and weed infested.
