Many factors must be considered when deciding when the best time is to get water to your garden and lawn. The time of day is one important factor—the cooler temperature and lack of wind in the morning hours help the water to soak into the soil, and the grass roots can absorb it before it evaporates. The afternoon is not an ideal time to water, as the heat and wind can cause much of the water to evaporate before it has a chance to be absorbed. Therefore, the best time to water your lawn is early in the morning, 10 a.m. for example, or late in the evening, 6 p.m. for example, when the temperature is cooler and the wind has died down. In order for your lawn to stay healthy and green all season long, watering at these opportune times will extend the life of your grass.
